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 (TG), and sterols. A fatty acid is a long-chain monocarboxylic acid, and a wax is the ester of a long-chain alcohol and a fatty acid. A triglyceride is the ester of a glycerol that contains three FA molecules. sterols are a special class of alcohols, containing a fused four-ring structure, or steroid nucleus. Sterols may combine with a fatty acid to form sterol esters.
