The chemical reactions and pathways involving lipids, compounds soluble in an organic solvent but not, or sparingly, in an aqueous solvent. Includes fatty acids; neutral fats, other fatty-acid esters, and soaps; long-chain (fatty) alcohols and waxes; sphingoids and other long-chain bases; glycolipids, phospholipids and sphingolipids; and carotenes, polyprenols, sterols, terpenes and other isoprenoids. The addition of an acetyl group to a sterol molecule. An acetyl group is CH3CO-, derived from acetic [ethanoic] acid. The chemical reactions and pathways involving alcohols, any of a class of compounds containing one or more hydroxyl groups attached to a saturated carbon atom. The removal of an acetyl group from a sterol molecule. An acetyl group is CH3CO-, derived from acetic [ethanoic] acid. The chemical reactions and pathways resulting in the formation of sterols, steroids with one or more hydroxyl groups and a hydrocarbon side-chain in the molecule. The chemical reactions and pathways involving ergosterol, (22E)-ergosta-5,7,22-trien-3-beta-ol, a sterol found in ergot, yeast and moulds. It is the most important of the D provitamins and is converted to vitamin D2 on irradiation with UV light. The chemical reactions and pathways resulting in the breakdown of sterols, steroids with one or more hydroxyl groups and a hydrocarbon side-chain in the molecule. The chemical reactions and pathways involving ecdysone, (22R)-2-beta,3-beta,14,22,25-pentahydroxycholest-7-en-6-one, an ecdysteroid found in insects. It is the inactive prohormone of the moulting hormone ecdysterone and may have intrinsic hormonal activity at other stages of insect development. The chemical reactions and pathways involving small molecules, any monomeric molecule of small relative molecular mass. The chemical reactions and pathways involving sterols, steroids with one or more hydroxyl groups and a hydrocarbon side-chain in the molecule. The chemical reactions and pathways involving steroids, compounds with a 1,2,cyclopentanoperhydrophenanthrene nucleus. The chemical reactions and pathways involving cholesterol, cholest-5-en-3 beta-ol, the principal sterol of vertebrates and the precursor of many steroids, including bile acids and steroid hormones. It is a component of the plasma membrane lipid bilayer and of plasma lipoproteins and can be found in all animal tissues.
