Hexadecanoic acid,10,16-dihydroxy- dideu

Omega hydroxy acids (ω-hydroxyacids) are naturally occurring linear aliphatic organics n carbon atoms in length, with a carboxyl group at position 1 (the beginning of the carboxylic acid family) and a hydroxyl group at the terminal position. A kind of acid. n (n > 3). These are subclasses of hydroxycarboxylic acids. The C16 and C18 omega hydroxy acids 16-hydroxypalmitic acid and 18-hydroxystearic acid are important monomers of cutin in plant cuticles. Polymeric cutin is formed through the transesterification of omega hydroxy acids and their intermediate chain-substituted derivatives such as 10,16-dihydroxypalmitic acid. Only plant epidermal cells synthesize cutin. Omega hydroxy fatty acids are also found in animals. Cytochrome P450 (CYP450) Microsomal omega-hydroxylases, such as human CYP4A11, CYP4A22, CYP4F2, and CYP4F3, mouse Cyp4a10 and Cyp4a12, rat Cyp4a1, Cyp4a2, Cyp4a3, and Cyp4a8, regulate arachidonic acid and many arachidonic acids Acid metabolism. metabolism. Corresponding light omega hydroxy products. This metabolism of arachidonic acid produces 20-hydroxyarachidonic acid (i.e., 20-hydroxyeicosatetraate or 20-HETE), a bioactive substance involved in a variety of physiological and pathological processes. Metabolism of certain bioactive arachidonic acid metabolites, such as leukotriene B4 and 5-hydroxyeicosatetraenoic acid, produces 20-hydroxylated products that are 100 to 1,000 times weaker than their respective precursors, resulting in The respective precursors are inactivated.
