Abstract
Lipid mediators participate in signal transduction pathways, proliferation, apoptosis, and membrane trafficking in the cell. Lipids are highly complex and diverse owing to the various combinations of polar headgroups, fatty acyl chains, and backbone structures. This structural diversity continues to pose a challenge for lipid analysis. Here we review the current state of the art in lipidomics research and discuss the challenges facing this field. The latest technological developments in mass spectrometry, the role of bioinformatics, and the applications of lipidomics in lipid metabolism and cellular physiology and pathology are also discussed.

Abstract
Analytical conditions for underivatized glycosphingolipids by using high-performance liquid chromatography atmospheric pressure ionization mass spectrometry (HPLC/API-MS) were investigated. The analysis was performed by using an ordinary reversed-phase column (4.6 X 150 or 4.6 X 250 mm) at a flow rate of 1 ml/min. The glycosphingolipids could be characterized from the HPLC/API-MS in terms of molecular weight, ceramide composition, and partial oligosaccharide sequence. In order to obtain an adequate spectrum the amount of material needed is in the range of a few micrograms of lipid. By selected ion monitoring the sensitivity of the method allowed characterization of only 60 ng of glycosphingolipid. The method will be very useful in the characterization of small quantities of glycosphingolipids from biological samples.

Abstract
The lipids accumulated in organs of patients with Gaucher's, Tay-Sachs, and Fabry's disease were identified by means of the combination of thin-layer chromatography and matrix-assisted secondary ion mass spectrometry. The total lipid extract of each lipidosis tissue was chromatographed on a TLC plate and then analyzed directly by mass spectrometry without elution of the sample from the TLC plate. The amount of material needed to obtain an adequate spectrum is in the order of a few micrograms of lipids per band for both positive and negative ion detection. By scanning the plates, mass spectral and chromatographic information can be obtained simultaneously, which was shown to be useful for the qualitative identification of the components on the plates.

Abstract
Conditions for normal phase high performance liquid chromatography-chemical ionization mass spectrometry of underivatized glycosphingolipids with the use of a moving belt transport interface were investigated. Chromatography was performed on a 2 mm ID X 3 cm column packed with 5 micron spherical silica. A gradient of increasing methanol and water in methylene chloride was used to resolve mono-, di-, tri-, and tetraglycosylceramides and sulfatides in less than 15 min. A polyimide belt was used to transport the sample residues to the mass spectrometer where ammonia chemical ionization mass spectrometry was used to obtain spectra. One to 5 micrograms of each component was sufficient to obtain full spectral scans. Mono- and dihexosylceramide spectra showed [M + H]+ ions of good abundance, while the higher glycosphingolipids have molecular weights that exceed the range of the mass spectrometer utilized. All glycosphingolipids gave ions characteristic of their ceramide, fatty acid, long chain base and carbohydrate components. Sequence information which reflected the relative position of hexose and N-acetylhexosamine residues was also obtained.

Abstract
We report herein the results of f.a.b.-m.s. experiments conducted on synthetic fragments of glycosaminoglycans, one of them representing the pentasaccharidic sequence present in heparin and responsible for the binding to antithrombin III, and the others being related to this sequence. The results indicate that f.a.b.-m.s. can be very useful for the structural analysis of sulfated glycosaminoglycans. The relatively small amounts of sample required enable molecular characterization at physiologically significant levels. In contrast to the chondroitin sulfates, the heparin saccharides analyzed and reported here do not provide sequence information. The data indicate that glycosidic rupture is not a process competing with the much more facile loss of N-sulfite residues. Dominating the spectra are a series of molecular-weight-related ions (distributed to indicate the associated countercation composition), and fragments related directly to sulfite elimination. This f.a.b.-induced, facile loss of sulfite may impose limitations in molecular-weight analysis for the larger oligomers.

Abstract
The native gangliosides GM3, GM1, Fuc-GM1, GD1a, GD1b, Fuc-GD1b, GT1b and GQ1b were analysed by fast atom bombardment mass spectrometry (FAB-MS) in the negative ion mode in a matrix of thioglycerol. After permethylation the same gangliosides were analysed by electron impact (EI) and FAB-MS in the positive ion mode. The negative ion mass spectra furnished information on the molecular weight, the ceramide moiety and the sequence of carbohydrate residues. The sites of attachment and the number of sialic acids present could be deduced directly from the pattern of sequence ions. After addition of sodium acetate positive ion FAB-spectra of the permethylated samples show intense pseudomolecular ions M + Na, that provide evidence on the homogeneity of the samples. In addition, the ceramide part, the oligosaccharide moiety obtained after cleavage of the glycosidic bond of the hexosamine residue, the whole carbohydrate chain and the sialic acids are represented by specific fragment ions. With EI-MS further information can be obtained on the sphingosine and fatty acid components of the ceramide residue. The data show, that the combination of soft ionization mass spectrometry with classical EI-MS gives valuable information on the structure and homogeneity of gangliosides. The method is also applicable to the structural elucidation or quantitation of more complex gangliosides or glycolipid mixtures using only micrograms of material.

Abstract
The fluffy layer fraction prepared from Bacterionema matruchotii was found to possess high activity for the biosynthesis of mycolic acids which were bound to an unknown compound by an alkali-labile linkage [T. Shimakata, M. Iwaki, and T. Kusaka (1984) Arch. Biochem. Biophys. 229, 329-339]. To determine the structure of the mycolate-containing compound, it was purified and analyzed by field desorption (FD) and secondary ion mass spectrometry (SI-MS). When non-labelled palmitic acid was used as a precursor in the in vitro biosynthetic system, the underivatized product had a cationized molecular ion, [M + Na]+, at m/z 843 in FD-MS and a protonated ion, [M + H]+, at m/z 821 in SI-MS, corresponding to the quasimolecular ion of trehalose monomycolate (C32:0). In SI-MS, characteristic fragment ions due to cleavage of glycosidic linkages were clearly detected in addition to the molecular ion. If [1-13C]palmitic acid was the precursor, 2 mass unit increases in both the quasimolecular and fragment ions were observed, indicating that two molecules of palmitate were incorporated into the product. alpha-Trehalose was found in the aqueous phase after saponification of the product. By the electron impact mass spectrometry of the trimethylsilylated product, the mycolate was found to be esterified with an hydroxyl group at position 6 of the trehalose molecule. These results clearly demonstrated that the predominant product synthesized by the fluffy layer fraction with palmitate as substrate was 6-monomycolate (C32:0) of alpha-D-trehalose. Because newly synthesized mycolic acid was mainly in the form of trehalose monomycolate instead of free mycolate or trehalose dimycolate, the role of trehalose in the biosynthesis of mycolic acid is discussed.

Abstract
This report describes the use of direct chemical ionization mass spectrometry with ammonia as the reagent gas (NH3-DCI) for structure analysis of underivatized, permethylated and permethylated and reduced glycosphingolipids. In contrast to ionization by electron impact, the NH3-DCI mass spectra exhibit intense molecular and carbohydrate sequence-related ions using microgram amounts of sample. Underivatized glycosphingolipids with up to two sugar residues yield abundant protonated and ammonia-cationized molecular ions and structurally significant fragments. Permethylation in conjunction with NH3-DCI can be used to obtain molecular weight as well as oligosaccharide sequence and branching information on neutral, acidic and complex-type glycosphingolipids with up to five sugar residues. Reduction of the permethylated derivatives gives rise to several new, structurally significant fragments in the corresponding NH3-DCI mass spectra which enable fatty acid and base compositions to be determined. Isotopically labeled reagent gases have been used to confirm the assignment of fragment structures and to demonstrate that the ions observed are unique to the NH3-DCI mass spectra.

Abstract
Field desorption (FD) and secondary ion mass spectrometry (SI-MS) mass spectra of several glycolipids are presented to demonstrate their potential for the analysis of glycolipids. FD and SI-MS give useful information on molecular weight, ceramide structure and sugar sequence. In general, FD provides clearer fragment ion peaks for the analysis of sugar sequence than SI-MS. For underivatized acidic glycolipids such as gangliosides, sulfatide and seminolipid, SI-MS provides quasimolecular ions which are hardly produced by FD. In contrast to underivatized gangliosides, permethylated samples give molecular ion species of high intensity in both FD and SI-MS, but no fragment ions pertinent to carbohydrate sequence could be observed in FD spectra. SI-MS spectra of permethylated samples provide good information on sugar chain structure. Thus FD and SI-MS mass spectra complement each other, and the combination of these ionization methods will provide powerful tools for glycolipid analysis.
