Simple lipids known as triglycerides which are eaters of fatty acids and glycerol. Waxes (or wax like substances) are also esters of fatty acids and long-chain or cyclic alcohols. This group includes the esters of cholesterol, Vitamin A and Vitamin D.
Compound lipids including phospholipids such as lecithin, cephalins and sphingomyelin.
Derived lipids including phospholipids such as glycerols, sterols, carotenoids and the fat-soluble vitamins A, D, E and K.
