The essential feature of a glycolipid is the presence of a monosaccharide or oligosaccharide bound to a lipid moiety. The most common lipids in cellular membranes are glycerolipids and sphingolipids, which have glycerol or a sphingosine backbones, respectively. Fatty acids are connected to this backbone, so that the lipid as a whole has a polar head and a non-polar tail.

Introduction. In chemical terms, triacylglycerols consist of the trihydric alcohol glycerol esterified, almost invariably, with long-chain fatty acids (C 14 to C 22).When the two primary hydroxyl groups are esterified with different fatty acids, the resulting triacylglycerol can display chiral asymmetry and thus be optically active, although this is usually too low to …
