Abstract
In vivo or whole-cell solid-state NMR is an emerging field which faces tremendous challenges. In most cases, cell biochemistry does not allow the labelling of specific molecules and an in vivo study is thus hindered by the inherent difficulty of identifying, among a formidable number of resonances, those arising from a given molecule. In this work we examined the possibility of studying, by solid-state NMR, the model organism Chlamydomonas reinhardtii fully and non-specifically 13C labelled. The extension of NMR-based dynamic filtering from one-dimensional to two-dimensional experiments enabled an enhanced selectivity which facilitated the assignment of cell constituents. The number of resonances detected with these robust and broadly applicable experiments appears to be surprisingly sparse. Various constituents, notably galactolipids abundant in organelle membranes, carbohydrates from the cell wall, and starch from storage grains could be unambiguously assigned. Moreover, the dominant crystal form of starch could be determined in situ. This work illustrates the feasibility and caveats of using solid-state NMR to study intact non-specifically 13C labelled micro-organisms.

Abstract
Lipid membranes composed of monogalactosyldiacylglycerol (MGDG) and dimyristoylphosphatidylcholine (DMPC) were studied by means of NMR spectroscopy. The macroscopic phase behaviour was investigated by (31)P NMR under stationary conditions, whereas microscopic properties such as segmental ordering were probed by two-dimensional (1)H-(13)C separated local field experiments under magic-angle spinning conditions. Our results clearly show that ordering/disordering effects occur for the headgroups as well as for the acyl chains when the sample composition is varied. In particular, the (1)H-(13)C dipolar couplings within the galactose headgroup of MGDG exhibited significant concentration dependence.

Abstract
The structures of two phosphoglucolipids from the membrane of Acholeplasma laidlawii, strain A-EF22 were determined by high resolution 13C-, 31P- and 1H-NMR. The lipids in question are 1,2-diacyl-3-O-[glycerophosphoryl-6-O-(alpha-D-glucopyranosyl- (1-->2)-O-alpha-D-glucopyranosyl)]-sn-glycerol (1) and 1,2-diacyl-3-O-[glycerophosphoryl-6-O-(alpha-D-glucopyranosyl-(1-- >2)- monoacyl-glycerophosphoryl-6-O-alpha-D-glucopyranosyl)]-sn-glycero l (2). Both lipids are thus derivatives of diglucosyldiacylglycerol. Previous reports on these lipids, based on insufficient chemical analyses, showed contradictory structures. A phosphoglycolipid having the structure of 2 has not been described previously.

Abstract
Model bilayer systems from individual purified chloroplast thylakoid membrane lipids, from reconstituted mixtures of these purified lipids, and from leaf total polar lipid extracts have been prepared in water, and the longitudinal relaxation times (T1's) of the individual carbon atoms of the fatty acyl chains measured by 13C-NMR spectroscopy. The T1's increase with increasing distance of the carbon atoms from the polar headgroups in all cases, and as the results from each of the preparations are similar, all can be used as models of chloroplast membrane bilayers. Relaxation time measurements on intact chloroplast thylakoid membranes indicate the presence of chlorophyll resonances in the 13C-NMR spectrum of the membrane.

Abstract
The 13C-NMR spectrum at 90.5 MHz has been obtained for the photosynthetic thylakoid membrane of spinach. Specific lipid and chlorophyll resonances can be assigned in the high resolution spectrum, although protein resonances are not observed. It can be estimated from resonance intensities that at least 30% of the plant chlorophyll contributes to the high resolution 13C spectrum with the remainder broadened by incomplete motional averaging. The resonance linewidths of the observed chlorophyll phytol chains are approximately the same as those of the lipid hydrocarbon chains, indicating a similar motional state and suggesting that this particular pool of chlorophyll is lipid-bound or at most only loosely associated with proteins.

Abstract
The motional properties of four monogalactosyldiacylglycerols isolated from photosynthetic membranes, and containing different fatty acid chain lengths and degrees of unsaturation, have been determined using 13C nuclear magnetic resonance. These properties have been compared with those of a lipid containing only saturated fatty acids. The 13C longitudinal relaxation times (T1) of the carbon atoms of the acyl chains in [2H4] methanol were measured as an index of the rates of motion of the lipid molecules and used to compare the relative fluidity of the acyl chains. The T1 values of the glyceryl and galactosyl carbon atoms in each monogalactosyldiacylglycerol are essentially constant, when allowance is made for concentration differences and the presence of two hydrogens on a methylene carbon versus one on a methine carbon. These results indicate similar rates of motion for the headgroup carbons in each lipid. However, for the acyl chains, the T1 values increase with the introduction of a double bond and increase further with additional unsaturation. This increase in the rate of motion only occurs at carbon atoms beyond the first double bond in an acyl chain. These results differ to those reported for monolayer experiments where changes in packing characteristics are predominantly dependent on the introduction of the first double bond and then vary little between species.

Abstract
The nuclear Overhauser effect (NOE) leads to changes in the intensity of signal(s) of a set of nuclei as a function of their respective distances. The use of NOE allows to obtain structural informations on peptides and proteins in solution as well as the study of interactions between small ligands and biomolecules. In this review, aspects of the basic theory of the NOE will be presented and the more recent applications of homonuclear and heteronuclear NOE's in biomolecules will be surveyed. Typical examples will be illustrated and limitations of the method will be discussed.

Abstract
The properties of seven monogalactosyldiacylglycerols and six digalactosyldiacylglycerols, isolated from photosynthetic membranes and possessing different levels of fatty acid unsaturation, have been studied by the monolayer technique and compared with those of the fully saturated compounds. In addition, the monolayer properties of sulphoquinovosyldiacylglycerols and phosphatidylglycerols from higher plant chloroplasts, and several hexadecenoic acids have been measured. Monogalactosyldiacylglycerols containing saturated fatty acids form a condensed monolayer similar to that of saturated phosphatidylcholines. The naturally occurring monogalactosyldiacylglycerols, of which the double bond index ranged from 0.6 to 3.9, possessed comparable force-area curves suggesting that headgroup interactions play a more important role in packing behaviour than in phosphatidylcholines. Although digalactosyldiacylglycerols containing fully saturated fatty acids form a more expanded monolayer than the corresponding monogalactosyldiacylglycerols, the degree of expansion of the monolayer due to the presence of unsaturated fatty acids in the naturally occurring digalactosyldiacylglycerols is much less than in monogalactosyldiacylglycerols. Monogalactosyldiacylglycerols and digalactosyldiacylglycerols from a single species have very similar monolayer properties, and the presence of sulphoquinovosyldiacylglycerols and phosphatidylglycerols in the proportions in which they occur in higher plant chloroplasts does not have any condensing effect on a monolayer of galactolipids.
