Glucuronic acid and gluconic acid are fermentation products in Kombucha tea. [9] Glucuronic acid is a precursor of ascorbic acid (vitamin C, formerly called L-hexuronic acid). Ascorbate can be biosynthesized by higher plants, algae, yeast and most animals. An adult goat produces ~13 g of vitamin C per day.
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.

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] They are sugars in which the hydroxyl group furthest from the carbonyl group has been oxidized to a carboxylic acid. Usually the sugar is an aldose, but fructuronic acid also occurs.
Gluconic acid is an organic compound with molecular formula C 6 H 12 O 7 and condensed structural formula HOCH 2 (CHOH) 4 CO 2 H. A white solid, it forms the gluconate anion in neutral aqueous solution. The salts of gluconic acid are known as "gluconates".
They are hemicellulosic plant cell wall polysaccharides, containing glucuronic acid and xylose as its main constituents. They are linear polymers of β-D-xylopyranosyl units linked by (1→4) glycosidic bonds, with many of the xylose units substituted with 2, 3 or 2,3-linked glucuronate residue, which are often methylated at position 4.
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.
The reaction is a transfer of two glucuronic acid groups including UDP glucuronic acid sequentially to the propionic acid groups of the bilirubin, primarily catalyzed by UGT1A1. [ 23 ] [ 24 ] [ 5 ] In greater detail about this reaction, a glucuronosyl moiety is conjugated to one of the propionic acid side chains, located on the C8 and C12 ...
