Lipid macromolecules primarily consist of long hydrocarbon chains or rings, making them hydrophobic and nonpolar. Common types include triglycerides, which are formed from glycerol and three fatty acids; phospholipids, consisting of glycerol, two fatty acids, and a phosphate group; and sterols, characterized by a multi-ring structure. These structural variations contribute to their diverse functions in biological membranes, energy storage, and signaling.
