Lipids. Lipids are very diverse hydrophobic macromolecules that fall under three main classes: fats, phospholipids, and steroids. Fats are not polymers because they are made of two types of molecules, glycerol and fatty acids, which are bound by ester linkages. Glycerol is an alcohol with 3 hydroxyl-group-bearing carbon atoms.
