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.
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".
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.
Enterohepatic circulation of drugs describes the process by which drugs are conjugated to glucuronic acid in the liver, excreted into bile, metabolized back into the free drug by intestinal bacteria, and the drug is then reabsorbed into plasma.
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.
The skeletal structure of an aldonic acid, gluconic acid (top), and its aldose, glucose (bottom). Aldonic acids are sugar acids with the general chemical formula, HO 2 C(CHOH) n CH 2 OH. They are obtained by oxidizing the aldehyde (-CHO group) of an aldose to form a carboxylic acid (-COOH group). [1] Aldonic acids are generally found in their ...
The most common disaccharide unit within heparan sulfate is composed of a glucuronic acid (GlcA) linked to N-acetylglucosamine (GlcNAc), typically making up around 50% of the total disaccharide units. Compare this to heparin, where IdoA(2S)-GlcNS(6S) makes up 85% of heparins from beef lung and about 75% of those from porcine intestinal mucosa.
It is also known as ascorbic acid water (Vitamin C dissolved in water) The molecular formula C 6 H 10 O 7 (molar mass: 194.14 g/mol, exact mass: 194.0427 u) may refer to: D-Galacturonic acid; Mannuronic acid; Glucuronic acid; Iduronic acid (IdoA)
