any member of a large and diverse group of oils, fats, and fatlike substances that occur in living organisms and that characteristically are soluble in lipid solvents but only sparingly soluble in aqueous solvents
Lipids constitute one of the four major classes of compounds found in living tissues (the others being carbohydrates, proteins, and nucleic acids) and they include: (1) fatty acids; (2) neutral fats (i.e. triacylglycerols), other fatty‐acid esters, and soaps; (3) long‐chain (or fatty) alcohols and waxes; (4) sphingoids and other long‐chain bases; (5) glycolipids, phospholipids, and sphingolipids; and (6) carotenes, polyprenols, sterols (and related compounds), terpenes, and other isoprenoids.
