Fatty acids are the simplest of the lipids, and are a constituent of many more complex lipids. Fatty acids can be oxidatively decomposed to CO with sufficient oxygen supply2And H2O, releases a large amount of energy, and thus fatty acids are one of the main energy sources of the body. It is mainly used for preparing daily cosmetics, detergents, industrial fatty acid salts, coatings, paints, rubbers, soaps, etc.
