Glycerol and Fatty Acids. One major class of lipids is called glycerolipids. Glycerolipids are composed of glycerol and fatty acids. Glycerol, whose structural formula is shown at right, has three carbon atoms, each of which has a hydroxyl (-OH) group bound to it.Fatty acids are fairly long linear hydrocarbon chains with a carboxylic acid group at one end.lycerol, whose structural formula is shown at right, has three carbon atoms, each of which has a hydroxyl (-OH) group bound to it.
