The important class of lipids called steroids are actually metabolic derivatives of terpenes, but they are customarily treated as a separate group. Steroids may be recognized by their tetracyclic skeleton, consisting of three fused six-membered and one five-membered ring, as shown in the diagram to the right.
Thus, unlike the other major groups of biological molecules--proteins, carbohydrates, and nucleic acids--lipids are categorized by a physical property rather than by structural features. CLASSIFICATION. Lipids can be classified in three subgroups based on chemical composition: hydrocarbons, simple lipids, and complex lipids. Hydrocarbons contain carbon and hydrogen only. Simple lipids contain C, H, and O, and complex lipids contain one or more additional elements, such as phosphorus, nitrogen, or sulfur. Simple Lipids Simple lipids can be segregated into structural types, which are fatty acids (FA), waxes, triglycerides
