Diversity of membrane lipids. Modern biological membranes are made of different types of lipids including phospholipids, sphingomyelin, and cholesterol. Changes in local concentration of these lipids can lead to microdomains in the membrane and potentially lipid rafts. This complexity and diversity is a large evolutionary advance over early membranes that were thought to self-assemble from monocarboxylate- and alcohol-derived 1-chained amphiphilic molecules.
