The β-D-methyl glycoside of glucuronic acid in the low energy 4 C 1 conformation of D-glucose. Glucuronic acid is a sugar acid derived from glucose, [2] with its sixth carbon atom oxidized to a carboxylic acid.
Hyaluronic acid is a polymer of disaccharides, which are composed of D-glucuronic acid and N-acetyl-D-glucosamine, linked via alternating β-(1→4) and β-(1→3) glycosidic bonds. Hyaluronic acid can be 25,000 disaccharide repeats in length. Polymers of hyaluronic acid can range in size from 5,000 to 20,000,000 Da in vivo.
Glucose (before oxidization) The Fischer projections of D-glucose (left) and D-glucuronic acid (right). Glucose's terminal carbon's primary alcohol group has been oxidized to a carboxylic acid. Uronic acids (/ ʊ ˈ r ɒ n ɪ k /) or alduronic acids are a class of sugar acids with both carbonyl and carboxylic acid functional groups. [1]
Other oxidized forms of d-galactose are d-galactonic acid (carboxylic group at C1) and meso-galactaric acid (carboxylic groups at C1 and C6). It is also a uronic acid or hexuronic acid. Naturally occurring uronic acids are d - glucuronic acid , d -galacturonic acid, l - iduronic acid and d - mannuronic 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 also participates in the heme degradation process of human. It is made from UDP-glucose by UDP-glucose 6-dehydrogenase (EC 1.1.1.22) using NAD+ as a cofactor.
Chondroitin sulfate is a sulfated glycosaminoglycan (GAG) [1] composed of a chain of alternating sugars (N-acetylgalactosamine and glucuronic acid). It is usually found attached to proteins as part of a proteoglycan. [1] A chondroitin chain can have over 100 individual sugars, each of which can be sulfated in variable positions and quantities.
Glucuronidation consists of transfer of the glucuronic acid component of uridine diphosphate glucuronic acid to a substrate by any of several types of UDP-glucuronosyltransferase. UDP-glucuronic acid (glucuronic acid linked via a glycosidic bond to uridine diphosphate) is an intermediate in the process and is formed in the liver.
There is no internationally accepted molecular standard for the composition of heparin, as it is a complex polymer of GAG units and uronic acids (including D-glucuronic acid, L-iduronic acid, and D-glucosamine). Position of N-acetyl, N-sulfate, and O-sulfate groups in these uronic acids can vary, as can the branching patterns of the chain.
