Glucosamine 6-phosphate

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

C6H14NO8P (259.04570140000004)

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).
