Journal ArticleDOI
TL;DR: It could be tentatively concluded that the susceptibility of the 1-acyl ester bond to lipase is influenced by the type of bond present at the 2-position, similar to that of phosphatidylcholine.

Journal ArticleDOI
TL;DR: The co-presence of both Lea- and Leb-glycolipids in the tissue of some individuals were noticed in glandular tissue and in adenocarcinoma tissue, and the patterns of blood-group glycolipid in adanocarc inoma tissue was distinguishable from that of normal glandularilage tissue by the absence ofBlood-group A- or B-glyColipid.

Journal ArticleDOI
W. Shankland1
TL;DR: It is shown that the proposed model satisfactorily accounted for the variation in size of the mixed micelles with the micellar Lecithin/Cholate ratio.

83 citations


Journal ArticleDOI
TL;DR: In this paper, the free lipids of Nocardia asteroides contain a series of corynomycolic acids ranging from C28H54O3 to C36H68O3.

78 citations


Journal ArticleDOI
TL;DR: In this paper, the preparation of crystalline L-α-GPC/CdCl2 complex from an average sample of commercial egg lecithin containing phosphatidylethanolamine (P.E.), sphingomyelin and other lipids is described.

64 citations


Journal ArticleDOI
TL;DR: When heated with toluene-p -sulphonic acid in the presence of methanol or dioxan, methyl linoleate gives mainly isomeric methyl octadecadienoates (∼ 22%) and 1,4-epoxides (tetrahydrofurans, ∼ 44%).

Journal ArticleDOI
TL;DR: The biosynthetic and degradation pathway taken together represent an additional route of serine transformation for the synthesis of the hydrophilic part of phospholipids.

56 citations



Journal ArticleDOI
TL;DR: Long-chain alcohols have been detected in lipid extracts of bovine and porcine brain and heart muscle and identified as major constituents in Hexadecanol, octade canol, Octadecenol and docosanol.

Journal ArticleDOI
TL;DR: The desaturation reaction involved in sphingosine biosynthesis thus appears to occur at the fatty acyl CoA level, although the possibility that it occurs at the ketonic level remains open.

Journal ArticleDOI
TL;DR: The following C 18 diynoic, cis,cis-dienoic and trans, trans -dienois acids have been prepared: 5,12, 6,12; 7,12 and 8,12.

Journal ArticleDOI
TL;DR: In addition to restricting the motions of phospholipids, cholesterol may alter the environment of the nitroxide residue of a spin-labelled lipid intercalated in lecithin liposomes to suggest that in natural membranes cholesterol may play a role in controlling the position of some membrane components.

Journal ArticleDOI
TL;DR: Starting from 3-sn-phosphatidylcholines carrying a 14C-labeled unsaturated fatty acid ester at the 2-position this method turned out to be very suitable for the preparation of unsaturated 14C -labeled 2-monoacyl choline phosphoglycerides.

Journal ArticleDOI
TL;DR: Recombinations with individual phospholipids confirm that opposite charges of lipids and proteins are essential for the initial interaction and are considered to be likely that in addition hydrophobic associations between proteins and lipids are formed.

Journal ArticleDOI
TL;DR: During enzymatic digestion, the original distribution ofospholipids in the cell envelopes remained almost unchanged, which indicates that the phospholipid composition of the plasma membrane corresponds in the main to that of the isolated cell envelope.

Journal ArticleDOI
TL;DR: Comparisons of the NMR spectra of trimethylsilyl derivatives of the lipids and several degradation products with those of reference compounds allowed the assignment of configurations of glycosidic linkages in the trihexosylceramide.

Journal ArticleDOI
TL;DR: In this article, Liver lecithins were isolated from normal or essential fatty acid-deficient rats, and these were separated into fractions containing mainly 1, 2, 3, 4 or 6 double bonds.



Journal ArticleDOI
TL;DR: The new spin label, 3-hydroxymethyl-2,2,5,5-tetramethylpyrrolidine-1-oxyl was prepared and phosphorylated with 1,2-distearoyl-sn-glycero-3-phosphoric acid, using tri-isopropylbenzenesulphonyl chloride as the condensing agent.

Journal ArticleDOI
TL;DR: In this article, the authors examined 12 species of Palmae seeds for the following parameters: fat content, fatty acid composition, and positional distribution of the fatty acids within the triglycerides.



Journal ArticleDOI
TL;DR: In this paper, a mixture of cyanogenetic, nonglycerol diesters (35%) and ordinary triglycerides was used as a seed oil for Cordia verbenacea DC.

Journal ArticleDOI
TL;DR: Several constituents of the cuticular leaf waxes of C. perenne L and L. album L have been examined by gas chromatography and mass spectrometry as mentioned in this paper.


Journal ArticleDOI
TL;DR: Intensity and wavelength studies indicate that the lipid in HDL2 affords the protein some protection from thermal and urea denaturation, suggesting that the organization of the lipids and proteins is much looser than occurs in erythrocyte membranes.
