Figure 21 Common steroid structures. Sterol esters exist commonly and are named using standard rules for esters. For example, the ester of cholesterol with palmitic acid would be named cholesterol palmitate. The standard nomenclature would also allow this molecule to be named 3-O-palmitoyl-3�-cholest-5-en-3-ol or 3-palmitoyl-3�-cholest-5-en-3-ol. D. Waxes Waxes (commonly called wax esters) are esters of fatty acids and long chain alcohols. Simple waxes are esters of medium chain fatty acids (16:0, 18:0, 18:1�9) and long chain aliphatic alcohols. The alcohols range in size from C8 to C18. Simple waxes are found on the surface of animals, plants, and insects and play a role in prevention Copyright 2002 by Marcel Dekker, Inc.
