PLAKOSIDES These unusual glycolipids were found in marine sponges. Various forms were described but they have in common a ceramide-like structure with […]
MONOGLYCOSYLCERAMIDES An amide bound between a fatty acid and the amine group of sphingosine or other related amino alcohols gives rise to […]
Ethanolamine glycerophospholipids Analogous structures to those described for choline phospholipids exist for the ethanolamine phospholipids. The pattern of fatty acid distribution generally shows […]
GLYCOLIPIDS BASED ON GLYCEROL These lipids consist of a mono- or oligosaccharide moiety linked glycosidically to the hydroxyl group of glycerol which may […]
DERIVATIVES OF NEUTRAL GLYCOSPHINGOLIPIDS A deacylated product of galactosylceramide (O-sphingosylgalactoside) is found in cerebral tissues and known as psychosine. Psychosine, although absent from […]
VITAMIN E The most active form of vitamin E, a-tocopherol, is a 6-hydroxychroman derivative (chromene) with methyl groups in position 2,5,7, and […]
PLASTOQUINONES A substituted quinone was isolated in a lipid extract of lucerne by Kofler in 1946. The discovery of ubiquinone and of its […]
Ethanolamine glycerophospholipids Analogous structures to those described for choline phospholipids exist for the ethanolamine phospholipids. The pattern of fatty acid distribution generally shows […]
FATTY ALCOHOLS Aliphatic alcohols occur naturally in free form (component of the cuticular lipids) but more usually in esterified (wax esters) or […]
MONOENOIC FATTY ACIDS In his classic studies on fatty acids from pork fat, Chevreul (1823) recognized the nature of oleic acid but it […]
