Glucosamine 6-phosphate

Phosphoric acid mono-((2R,3S,4R,5R)-5-amino-2,3,4-trihydroxy-6-oxo-hexyl) ester

C6H14NO8P (259.0457)

Glucosamine 6-phosphate (CAS: 3616-42-0) is normally produced in endothelial cells via de novo glucosamine synthesis by the enzyme fructose-6-phosphate amidotransferase and the modulation of this pathway by hyperglycemia and glutamine. Glutamine-fructose-6-phosphate amidotransferase (GFAT) catalyzes the first committed step in the pathway for biosynthesis of hexosamines in mammals.It is a member of the N-terminal nucleophile class of amidotransferases, GFAT transfers the amino group from the L-glutamine amide to D-fructose 6-phosphate, producing glutamic acid and glucosamine 6-phosphate. As glucosamine inhibits endothelial nitric oxide synthesis it has important implications for impaired endothelium-dependent relaxation and vascular dysfunction in diabetes mellitus (PMID:11270676, 11842094).

Glucosamine 6-sulfate

{[(2R,3S,4R,5R,6R)-5-amino-3,4,6-trihydroxyoxan-2-yl]methoxy}sulfonic acid

C6H13NO8S (259.0362)

Glucosamine 6-sulfate is a naturally occurring compound present in many of the bodys tissues, and belongs to a class of compounds known as glycosaminoglycans (GAGs). Glucosamine 6-sulfate is being used in the treatment of arthritis. Glucosamine for arthritis products is usually formulated as the hydrochloride salt or glucosamine sulfate and often combined with chondroitin sulphate. It is notable that while both the hydrochloride salt and glucosamine sulfate are used in pharmaceutical preparations, glucosamine sulfate is thought to have a higher biological activity due to the presence of the sulfate. It should also be noted that there is a large cost difference between the two salts, with the hydrochloride salt being significantly less expensive.
