Uridine diphosphate glucuronic acid

UDP-glucuronic acid is a sugar used in the creation of polysaccharides and is an intermediate in the biosynthesis of ascorbic acid (except in primates and guinea pigs). It is central to the glucuronidation reaction, in which waste molecules in the body, such as heme, are made more hydrophilic to facilitate their excretion.

It is made from UDP-glucose by UDP-glucose 6-dehydrogenase (EC 1.1.1.22) using NAD+ as a cofactor. It is the source of the glucuronosyl group in glucuronosyltransferase reactions.^[1][2]
