beta-D-Glucuronic acid
IUPAC 名称
(2S,3S,4S,5R,6S)-3,4,5,6-tetrahydroxyoxane-2-carboxylic acid
描述
Glucuronic acid is a carboxylic acid that has the structure of a glucose molecule that has had its sixth carbon atom (of six total) oxidized. The salts of glucuronic acid are known as glucuronates. Glucuronic acid is highly soluble in water. In the animal body, glucuronic acid is often linked to poisonous substances to allow for subsequent elimination, and to hormones to allow for easier transport. These linkages involve O-glycosidic bonds. The process is known as glucuronidation, and the resulting substances are known as glucuronides (or glucuronosides). Glucuronidation uses UDP-glucuronic acid (glucuronic acid linked via a glycosidic bond to uridine diphosphate) as an intermediate. UDP-glucuronic acid is formed in the liver of all animals. [HMDB]
Widely distributed in plants, where it occurs in gums, mucilages, saponins and flavone glycosides and in animals as a constituent of mucopolysaccharides. Glycosides are formed in the liver to detoxify poisonous hydroxyl-containing substances. Phenyl, cresyl and indoxyl glycosides are present in normal urine. [CCD]. beta-D-Glucuronic acid is found in many foods, some of which are cashew nut, american cranberry, sour cherry, and soy bean.
