Abstract
Oxylipins are one of the most important classes of bioregulators, biosynthesized through the oxidative metabolism of unsaturated fatty acids in various aerobic organisms. Oxylipins are bioregulators that maintain homeostasis at the cellular and organismal levels. The most important oxylipins are mammalian eicosanoids and plant octadecanoids. In plants, the main source of oxylipins is the lipoxygenase cascade, the key enzymes of which are nonclassical cytochromes P450 of the CYP74 family, namely allene oxide synthases (AOSs), hydroperoxide lyases (HPLs), and divinyl ether synthases (DESs). The most well-studied plant oxylipins are jasmonates (AOS products) and traumatin and green leaf volatiles (HPL products), whereas other oxylipins remain outside of the focus of researchers' attention. Among them, there is a large group of epoxy hydroxy fatty acids (epoxyalcohols), whose biosynthesis has remained unclear for a long time. In 2008, the first epoxyalcohol synthase of lancelet Branchiostoma floridae, BfEAS (CYP440A1), was discovered. The present review collects data on EASs discovered after BfEAS and enzymes exhibiting EAS activity along with other catalytic activities. This review also presents the results of a study on the evolutionary processes possibly occurring within the P450 superfamily as a whole.

Abstract
Divinyl ether synthases (DESs) are the enzymes occurring in numerous plant species and catalysing the dehydration of fatty acid hydroperoxides to divinyl ether oxylipins, playing self-defensive and antipathogenic roles in plants. Previously, the DES activities and divinyl ethers were detected in some monocotyledonous plants, including the asparagus (Asparagus officinalis L.). The cloning of the open reading frame of the CYP74H2 gene of asparagus and catalytic properties of the recombinant CYP74H2 protein are described in the present work. The CYP74H2 utilized the 13(S)-hydroperoxide of linoleic acid (13(S)-HPOD) as a preferred substrate and specifically converted it to the divinyl ether, (9Z,11Z)-12-[(1'E)-hexenyloxy]-9,11-dodecadienoic acid, (11Z)-etheroleic acid. The second most efficient substrate after the 13(S)-HPOD was the 9(S)-hydroperoxide of α-linolenic acid (9(S)-HPOT), which was converted to the previously undescribed product, (1'Z)-colnelenic acid. The 13(S)-hydroperoxide of α-linolenic acid (13(S)-HPOT) and 9(S)-hydroperoxide of linoleic acid (9(S)-HPOD) were less efficient substrates for CYP74H2. Both 13(S)-HPOT and 9(S)-HPOD were transformed to divinyl ethers, (11Z)-etherolenic and (1'Z)-colneleic acids, respectively. The CYP74H2 is a second cloned monocotyledonous DES after the garlic CYP74H1 and the first DES biosynthesizing the (1'Z)-colneleic and (1'Z)-colnelenic acids.

Abstract
Oxylipins constitute a family of oxidized fatty acids, that are well known as tissue hormones in mammals. They contribute to inflammation and its resolution. The major classes of these lipid mediators are inflammatory prostaglandins (PGs) and leukotrienes (LTs) as well as pro-resolving resolvins (Rvs). Understanding their biosynthetic pathways and modes of action is important for anti-inflammatory interventions. Besides mammals, marine algae also biosynthesize mammalian-like oxylipins and thus offer new opportunities for oxylipin research. They provide prolific sources for these compounds and offer unique opportunities to study alternative biosynthetic pathways to the well-known lipid mediators. Herein, we discuss recent findings on the biosynthesis of oxylipins in mammals and algae including an alternative pathway to prostaglandin E2 , a novel pathway to a precursor of leukotriene B4 , and the production of resolvins in algae. We evaluate the pharmacological potential of the algal metabolites with implications in health and disease.

Abstract
Screening of linolipins, i.e. galactolipids containing esterified residues of divinyl ether oxylipins, in the leaves of several higher plants revealed the presence of these complex oxylipins in the meadow buttercup leaves. The rapid accumulation of linolipins occurred in the injured leaves of meadow buttercup, while intact leaves possessed no linolipins. These oxylipins were isolated from the injured leaves, separated and purified by HPLC. The structural analyses of linolipins by UV, mass-spectroscopy and NMR spectroscopy resulted in the identification of eight molecular species. Three of them were identical to linolipins B-D found earlier in the leaves of flax (Linum usitatissimum L.). Other molecular species were identified as 1-O-(ω5Z)-etherolenoyl-2-O-dinor-(ω5Z)-etherolenoyl-3-O-β-D-galactopyranosyl-sn-glycerol, 1-O-(ω5Z)-etherolenoyl-2-O-(7Z,10Z,13Z)-hexadecatrienoyl-3-O-β-D-galactopyranosyl-sn-glycerol, 1-O-(ω5Z)-etherolenoyl-2-O-(7Z,10Z)-hexadecadienoyl-3-O-β-D-galactopyranosyl-sn-glycerol, 1-O-(ω5Z)-etherolenoyl-2-O-α-linolenoyl-3-O-β-D-galactopyranosyl-sn-glycerol, and 1-O-(ω5Z)-etherolenoyl-2-O-palmitoyl-3-O-(α-galactopyranosyl-1-6-β-D-galactopyranosyl)-sn-glycerol. The trivial names "linolipins E, F, G, H and I," respectively, have been ascribed to these novel complex oxylipins.

Abstract
Enzymes of CYP74 family play the central role in the biosynthesis of physiologically important oxylipins in land plants. Although a broad diversity of oxylipins is known in the algae, no CYP74s or related enzymes have been detected in brown algae yet. Cloning of the first CYP74-related gene CYP5164B1 of brown alga Ectocarpus siliculosus is reported in present work. The recombinant protein was incubated with several fatty acid hydroperoxides. Linoleic acid 9-hydroperoxide (9-HPOD) was the preferred substrate, while linoleate 13-hydroperoxide (13-HPOD) was less efficient. α-Linolenic acid 9- and 13-hydroperoxides, as well as eicosapentaenoic acid 15-hydroperoxide were inefficient substrates. Both 9-HPOD and 13-HPOD were converted into epoxyalcohols. For instance, 9-HPOD was turned primarily into (9S,10S,11S,12Z)-9,10-epoxy-11-hydroxy-12-octadecenoic acid. Both epoxide and hydroxyl oxygen atoms of the epoxyalcohol were incorporated mostly from [18O2]9-HPOD. Thus, the enzyme exhibits the activity of epoxyalcohol synthase (EsEAS). The results show that the EsEAS isomerizes the hydroperoxides into epoxyalcohols via epoxyallylic radical, a common intermediate of different CYP74s and related enzymes. EsEAS can be considered as an archaic prototype of CYP74 family enzymes.

Abstract
Marine algae are rich and heterogeneous sources of great chemical diversity, among which oxylipins are a well-recognized class of natural products. Algal oxylipins comprise an assortment of oxygenated, halogenated, and unsaturated functional groups and also several carbocycles, varying in ring size and position in lipid chain. Besides the discovery of structurally diverse oxylipins in macroalgae, research has recently deciphered the role of some of these metabolites in the defense and innate immunity of photosynthetic marine organisms. This review is an attempt to comprehensively cover the available literature on the chemistry, biosynthesis, ecology, and potential bioactivity of oxylipins from marine macroalgae. For a better understanding, enzymatic and nonenzymatic routes were separated; however, both processes often occur concomitantly and may influence each other, even producing structurally related molecules.

Abstract
Green tissues of spikemoss Selaginella martensii Spring possessed the complex oxylipins patterns. Major oxylipins were the products of linoleic and α-linolenic acids metabolism via the sequential action of 13-lipoxygenase and divinyl ether synthase (DES) or allene oxide synthase (AOS). AOS products were represented by 12-oxophytodienoic acid (12-oxo-PDA) isomers. Exceptionally, S. martensii possesses high level of 12-oxo-9(13),15-PDA, which is very uncommon in flowering plants. Separate divinyl ethers were purified after micro-preparative incubations of linoleic or α-linolenic acids with homogenate of S. martensii aerial parts. The NMR data allowed us to identify all geometric isomers of divinyl ethers. Linoleic acid was converted to divinyl ethers etheroleic acid, (11Z)-etheroleic acid and a minority of (ω5Z)-etheroleic acid. With α-linolenate precursor, the specificity of divinyl ether biosynthesis was distinct. Etherolenic and (ω5Z)-etherolenic acids were the prevailing products while (11Z)-etherolenic acid was a minor one. Divinyl ethers are detected first time in non-flowering land plant. These are the first observations of fatty acid metabolism through the lipoxygenase pathway in spikemosses (Lycopodiophyta).

Abstract
Phytoprostanes, autoxidation products of α-linolenic acid, have been studied in several plant species, but information regarding the natural occurrence of this large family of biologically active oxidized lipids in macroalgae is still scarce. In this work, the free phytoprostane composition of 24 macroalgae species belonging to Chlorophyta, Phaeophyta, and Rhodophyta was determined through a recently validated UHPLC-QqQ-MS/MS method. The phytoprostane profiles varied greatly among all samples, F1t-phytoprostanes and L1-phytoprostanes being the predominant and minor classes, respectively. No correlation between the amounts of α-linolenic acid in alga material and phytoprostane content was found. Therefore, it was hypothesized that the observed variability could be species-specific or result from interspecific interactions. This study provides new insight about the occurrence of phytoprostanes in macroalgae and opens doors for future exploitation of these marine photosynthetic organisms as sources of potentially bioactive oxylipins, encouraging their incorporation in food products and nutraceutical and pharmaceutical preparations for human health.

Abstract
Enzymes of the CYP74 family, including the divinyl ether synthase (DES), play important roles in plant cell signalling and defence. The potent DES activities have been detected before in the leaves of the meadow buttercup (Ranunculus acris L.) and few other Ranunculaceae species. The nature of these DESs and their genes remained unrevealed. The PCR with degenerate primers enabled to detect the transcript of unknown P450 gene assigned as CYP74Q1. Besides, two more CYP74Q1 isoforms with minimal sequence variations have been found. The full length recombinant CYP74Q1 protein was expressed in Escherichia coli. The preferred substrates of this enzyme are the 13-hydroperoxides of α-linolenic and linoleic acids, which are converted to the divinyl ether oxylipins (ω5Z)-etherolenic acid, (9Z,11E)-12-[(1'Z,3'Z)-hexadienyloxy]-9,11-dodecadienoic acid, and (ω5Z)-etheroleic acid, (9Z,11E)-12-[(1'Z)-hexenyloxy]-9,11-dodecadienoic acid, respectively, as revealed by the data of mass spectrometry, NMR and UV spectroscopy. Thus, CYP74Q1 protein was identified as the R. acris DES (RaDES), a novel DES type and the opening member of new CYP74Q subfamily.

Kumari P, Reddy R, Jha B. Quantification of selected endogenous hydroxy-oxylipins from tropical marine macroalgae. MARINE BIOTECHNOLOGY (NEW YORK, N.Y.) 2014; 16:74-87. [PMID: 24052492 DOI: 10.1007/s10126-013-9533-0] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/18/2012] [Accepted: 07/08/2013] [Indexed: 05/23/2023]
Abstract
The present study investigated the contents of hydroxy-oxylipins hydroxyoctadecadienoic acids (HODEs), hydroxyoctadecatrienoic acids (HOTrEs), and hydroxyeicosatetraenoic acids (HETEs) in 40 macroalgae belonging to the Chlorophyceae, Rhodophyceae and, Phaeophyceae. The hydroxy-oxylipin content was low and ranged from 0.14 ± 0.012 ng/g (Codium dwarkense) to 8,161.9 ± 253 ng/g (Chaetomorpha linum) among the Chlorophyceae, 345.4 ± 56.8 ng/g (Scytosiphon lomentaria) to 2,574.5 ± 155.5 ng/g (Stoechospermum marginatum) among the Phaeophyceae, and 19.4 ± 2.2 ng/g (Laurencia cruciata) to 1,753.1 ± 268.2 ng/g in Gracilaria corticata v. folifera) among the Rhodophyceae on fresh weight basis (p ≤ 0.01). The concentrations of C18-oxylipins were greater than C20-oxylipins in all the investigated macroalgae, except forUlva linza, Codium sursum, Dictyopteris deliculata, S. marginatum, Sargassum tenerrimum, Gracilaria spp. (except G. textorii), Rhodymenia sonderi, and Odonthalia veravalensis.The macroalgal species rich in HODEs, HOTrEs, and HETEs were segregated using principal component analysis. The red macroalgae showed the highest contents of HETEs, followed by brown and green macroalgae in consistent with their PUFA profiles. The relative contents of isomeric forms of oxylipins displayed the species-specific positional selectivity of lipoxygenase (LOX) enzyme in macroalgae. All the species exhibited 13-LOX specificity for linoleic acid analogous of higher plants, while 21 out of 40 species showed 9-LOX selectivity for the oxygenation of α-linolenic acid. No trend was observed for the oxygenation of arachidonic acid in macroalgae, except for in the Halymeniales, Ceramiales (except L. cruciata), and Corallinales. This study infers that LOX products, octadecanoids and eicosanoids, described in macroalgal taxa were similar to those of higher plants and mammals, respectively, and thus can be utilized as an alternative source of chemically synthesized oxylipin analogues in therapeutics, cosmetics, and nutritional oil supplements.

Abstract
Two complex oxylipins (linolipins C and D) were isolated from the leaves of flax plants inoculated with phytopathogenic bacteria Pectobacterium atrosepticum. Their structures were elucidated based on UV, MS and NMR spectroscopic data. Both oxylipins were identified as digalactosyldiacylglycerol (DGDG) molecular species. Linolipin C contains one residue of divinyl ether (ω5Z)-etherolenic acid and one α-linolenate residue at sn-1 and sn-2 positions, respectively. Linolipin D possesses two (ω5Z)-etherolenic acid residues at both sn-1 and sn-2 positions. The rapid formation (2-30min) of linolipins C and D alongside with linolipins A and B occurred in the flax leaves upon their damage by freezing-thawing.

Abstract
Non-classical P450s of CYP74 family control several enzymatic conversions of fatty acid hydroperoxides to bioactive oxylipins in plants, some invertebrates and bacteria. The family includes two dehydrases, namely allene oxide synthase (AOS) and divinyl ether synthase (DES), and two isomerases, hydroperoxide lyase (HPL) and epoxyalcohol synthase. To study the interconversion of different CYP74 enzymes, we prepared the mutant forms V379F and E292G of tobacco (CYP74D3) and flax (CYP74B16) divinyl ether synthases (DESs), respectively. In contrast to the wild type (WT) enzymes, both mutant forms lacked DES activity. Instead, they produced the typical AOS products, α-ketols and (in the case of the flax DES mutant) 12-oxo-10,15-phytodienoic acid. This is the first demonstration of DES into AOS conversions caused by single point mutations.

Abstract
Enzymes of the CYP74 family (P450 superfamily) play a key role in the plant lipoxygenase signalling cascade. Recently we detected a pathogen inducible divinyl ether synthase (DES) in flax leaves [Chechetkin, Blufard, Hamberg, Grechkin, 2008]. This prompted us to examine the CYP74 genes in the flax leaf transcriptome. Since the flax genome is not sequenced, we used the PCR approach with degenerate primers related to the conserved domains of selected CYP74 genes; this revealed several CYP74 transcripts in flax leaves. One transcript belongs to the previously described allene oxide synthase (LuAOS, CYP74A, GenBank ID: U00428.1). Another one contains the ORF (1473 bp) of an unknown CYP74B16 gene. Three more nearly identical sequences, including one expressed pseudogene, were also identified. The recombinant CYP74B16 protein expressed in Escherichia coli had 491 amino acid residues and MW of 56 kDa. The preferred substrate of this enzyme is the 13-hydroperoxide of α-linolenic acid, and the reaction product was identified by mass spectrometry, NMR and UV spectroscopy as the divinyl ether (9Z,11E)-12-[(1'Z,3'Z)-hexadienyloxy]-9,11-dodecadienoic acid, (ω5Z)-etherolenic acid. All previously known CYP74B subfamily enzymes are hydroperoxide lyases. The novel flax enzyme CYP74B16 (LuDES) is an unprecedented DES member of the CYP74B subfamily.

Abstract
Incubations of linoleic acid with cell-free preparations from Lily-of-the-Valley (Convallaria majalis L., Ruscaceae) roots revealed the presence of 13-lipoxygenase and divinyl ether synthase (DES) activities. Exogenous linoleic acid was metabolized predominantly into (9Z,11E,1'E)-12-(1'-hexenyloxy)-9,11-dodecadienoic (etheroleic) acid. Its identification was confirmed by the data of ultraviolet spectroscopy, mass spectra, (1)H NMR, COSY, catalytic hydrogenation. The isomeric divinyl ether (8E,1'E,3'Z)-12-(1',3'-nonadienyloxy)-8-nonenoic (colneleic) acid was detected as a minor product. Incubations with linoleic acid hydroperoxides revealed that 13-hydroperoxide was a preferential substrate, while the 9-hydroperoxide was utilized with lesser efficiency.

Abstract
Incubation of linoleic acid with an enzyme preparation from leaves of flax (Linum usitatissimum L.) led to the formation of a divinyl ether fatty acid, i.e. (9Z,11E,1'Z)-12-(1'-hexenyloxy)-9,11-dodecadienoic [(omega5Z)-etheroleic] acid, as well as smaller amounts of 13-hydroxy-9(Z),11(E)-octadecadienoic acid. The 13-hydroperoxide of linoleic acid afforded the same set of products, whereas incubations of alpha-linolenic acid and its 13-hydroperoxide afforded the divinyl ether (9Z,11E,1'Z,3'Z)-12-(1',3'-hexadienyloxy)-9,11-dodecadienoic [(omega5Z)-etherolenic] as the main product. Identification of both divinyl ethers was substantiated by their UV, mass-, (1)H NMR and COSY spectral data. In addition to the 13-lipoxygenase and divinyl ether synthase activities demonstrated by these results, flax leaves also contained allene oxide synthase activity as judged by the presence of endogenously formed (15Z)-cis-12-oxo-10,15-phytodienoic acid in all incubations.

Abstract
Hydroxy fatty acids from Euglena gracilis were identified by reverse-phase high performance liquid chromatography coupled to a mass spectrometer run in atmospheric pressure chemical ionization positive ion mode. These metabolites were converted to methyl esters to improve stability and chromatographic properties. A detection limit of 20 pg/microl per injection was determined for 5-HETE methyl ester based on the signal to noise ratio of the m/z 317 ion which corresponds to the loss of a hydroxyl group (M-17) and the major fragment in all HETE methyl esters studied. This is the first report for these metabolites in E. gracilis.

Abstract
Nine novel oxylipin metabolites together with several known ones were isolated from the brown alga Eisenia bicyclis. Five (1-5) of them are ecklonialactone derivatives containing a chlorine or an iodine atom, and two (6 and 7) are cymathere type oxylipins with a lactone ring or a chlorine atom. The structures of these oxylipin metabolites were confirmed by NMR and mass spectroscopy and compared with spectral data in the literature. The postulated biosynthetic pathway of these metabolites is discussed.

Abstract
"Heterolytic" hydroperoxide lyase (HPL) and divinyl ether synthase (DES) are important enzymes of the plant lipoxygenase pathway. HPL cleaves fatty acid hydroperoxides into the aldehyde fragments. DES converts hydroperoxides into the divinyl ethers. The present paper is concerned with recent studies on HPL and DES including their occurrence, properties, mechanisms of action, the cloning of their cDNAs and physiological importance of the enzymes and their products.

Abstract
[1-14C]Linolenic acid was incubated with homogenates of leaves from the aquatic plants Ranunculus lingua (greater spearwort) or R. peltatus (pond water-crowfoot). Analysis by reversed-phase high-performance liquid radiochromatography demonstrated the formation of a new divinyl ether FA, i.e., 12-[1'(E),3'(Z)-hexadienyloxyl-9(Z), 11 (Z)-dodecadienoic acid [11 (Z)-etherolenic acid] as well as a smaller proportion of omega5(Z)-etherolenic acid previously identified in terrestrial Ranunculus plants. The same divinyl ethers were formed upon incubation of 13(S)-hydroperoxy-9(Z),11 (E),15(Z)-octadecatrienoic acid, a lipoxygenase metabolite of linolenic acid, whereas the isomeric hydroperoxide, 9(S)-hydroperoxy-10(E),12(Z),15(Z)-octadecatrienoic acid, was not converted into divinyl ethers in R. lingua or R. peltatus. Incubation of [1-14C]linoleic acid or 13(S)-hydroperoxy-9(Z), 11 (E)-octadecadienoic acid produced the divinyl ether 12-[1'(E)-hexenyloxyl-9(Z),11(Z)-dodecadienoic acid [11(Z)-etheroleic acid] and a smaller amount of omega5(Z)-etheroleic acid. The experiments demonstrated the existence in R. lingua and R. peltatus of a divinyl ether synthase distinct from those previously encountered in higher plants and algae.

Abstract
Lipoxygenase-derived fatty acid hydroperoxides are metabolized by CYP74 cytochrome P-450s to various oxylipins that play important roles in plant growth and development. Here, we report the characterization of a Lycopersicon esculentum (tomato) cDNA whose predicted amino acid sequence defines a previously unidentified P-450 subfamily (CYP74D). The recombinant protein, expressed in Escherichia coli, displayed spectral properties of a P-450. The enzyme efficiently metabolized 9-hydroperoxy linoleic acid and 9-hydroperoxy linolenic acid but was poorly active against the corresponding 13-hydroperoxides. Incubation of recombinant CYP74D with 9-hydroperoxy linoleic acid and 9-hydroperoxy linolenic acid yielded divinyl ether fatty acids (colneleic acid and colnelenic acid, respectively), which have been implicated as plant anti-fungal toxins. This represents the first identification of a cDNA encoding a divinyl ether synthase and establishment of the enzyme as a CYP74 P-450. Genomic DNA blot analysis revealed the existence of a single divinyl ether synthase gene located on chromosome one of tomato. In tomato seedlings, root tissue was the major site of both divinyl ether synthase mRNA accumulation and enzyme activity. These results indicate that developmental expression of the divinyl ether synthase gene is an important determinant of the tissue specific synthesis of divinyl ether oxylipins.

Abstract
A pathogen-inducible oxygenase in tobacco leaves and a homologous enzyme from Arabidopsis were recently characterized (Sanz, A., Moreno, J. I., and Castresana, C. (1998) Plant Cell 10, 1523-1537). Linolenic acid incubated at 23 degrees C with preparations containing the recombinant enzymes underwent alpha-oxidation with the formation of a chain-shortened aldehyde, i.e., 8(Z),11(Z), 14(Z)-heptadecatrienal (83%), an alpha-hydroxy acid, 2(R)-hydroxy-9(Z),12(Z),15(Z)-octadecatrienoic acid (15%), and a chain-shortened fatty acid, 8(Z),11(Z),14(Z)-heptadecatrienoic acid (2%). When incubations were performed at 0 degrees C, 2(R)-hydroperoxy-9(Z),12(Z),15(Z)-octadecatrienoic acid was obtained as the main product. An intermediary role of 2(R)-hydroperoxy-9(Z), 12(Z),15(Z)-octadecatrienoic acid in alpha-oxidation was demonstrated by re-incubation experiments, in which the hydroperoxide was converted into the same alpha-oxidation products as those formed from linolenic acid. 2(R)-Hydroperoxy-9(Z),12(Z), 15(Z)-octadecatrienoic acid was chemically unstable and had a half-life time in buffer of about 30 min at 23 degrees C. Extracts of cells expressing the recombinant oxygenases accelerated breakdown of the hydroperoxide (half-life time, about 3 min at 23 degrees C), however, this was not attributable to the recombinant enzymes since the same rate of hydroperoxide degradation was observed in the presence of control cells not expressing the enzymes. No significant discrimination between enantiomers was observed in the degradation of 2(R,S)-hydroperoxy-9(Z)-octadecenoic acid in the presence of recombinant oxygenases. A previously studied system for alpha-oxidation in cucumber was re-examined using the newly developed techniques and was found to catalyze the same conversions as those observed with the recombinant enzymes, i.e. enzymatic alpha-dioxygenation of fatty acids into 2(R)-hydroperoxides and a first order, non-stereoselective degradation of hydroperoxides into alpha-oxidation products. It was concluded that the recombinant enzymes from tobacco and Arabidopsis were both alpha-dioxygenases, and that members of this new class of enzymes catalyze the first step of alpha-oxidation in plant tissue.

Abstract
[1-14C]alpha-Linolenic acid was incubated with a particulate fraction of homogenate of leaves of the meadow buttercup (Ranunculus acris L.). The main product was a divinyl ether fatty acid, which was identified as 12-[1'(Z),3'(Z)-hexadienyloxy]-9(Z),11(E)-dodecadienoic acid. Addition of glutathione peroxidase and reduced glutathione to incubations of alpha-linolenic acid almost completely suppressed formation of the divinyl ether acid and resulted in the appearance of 13(S)-hydroxy-9(Z), 11(E),15(Z)-octadecatrienoic acid as the main product. This result, together with the finding that 13(S)-hydroperoxy-9(Z), 11(E),15(Z)-octadecatrienoic acid served as an efficient precursor of the divinyl ether fatty acid, indicated that divinyl ether biosynthesis in leaves of R. acris occurred by a two-step pathway involving an omega6-lipoxygenase and a divinyl ether synthase. Incubations of isomeric hydroperoxides derived from alpha-linolenic and linoleic acids with the enzyme preparation from R. acris showed that 13(S)-hydroperoxy-9(Z),11(E)-octadecadienoic acid was transformed into the divinyl ether 12-[1'(Z)-hexenyloxy]-9(Z), 11(E)-dodecadienoic acid. In contrast, neither the 9(S)-hydroperoxides of linoleic or alpha-linolenic acids nor the 13(R)-hydroperoxide of alpha-linolenic acid served as precursors of divinyl ethers.

Abstract
Marine organisms, especially marine algae, are extremely rich in a diversity of novel oxylipin structures. Many of these oxylipins contain functionalities and rings of a type and location unknown in mammalian systems. In this perspective reviewing marine oxylipins, a proposal is formulated for the central intermediacy of an epoxy allylic carbocation in the biogenesis of these diverse structures. This proposal is strengthened by the relatively large number of examples which are consistent with this type of mechanistic transformation.

Abstract
Diverse marine life, including algae, sponges, molluscs, corals, tunicates, and bacteria, have been found to possess a variety of structurally unique oxylipins. The algae are the best characterized of these organisms for their oxylipins, which have now been described from more than 30 species representing the three major groups of macrophytic algae (Rhodophyta = reds, Chlorophyta = greens, and Phaeophyceae = browns). A number of recent studies have sought to understand the biosynthetic origin and mechanistic chemistry which leads to the formation of these unique marine substances. In general, the red algae metabolize C20 acids via 12-lipoxygenase-initiated pathways, green algae metabolize C18 acids at C-9 and C-13, and brown algae metabolize both C18 and C20 acids, principally by lipoxygenases with n-6 specificity. This review updates the records of new oxylipins from marine algae and describes thoughts on their biogenesis as well as specific experiments aimed at probing these hypotheses.
