Identification
Name:D-Galactosamine 6-phosphate
DescriptionD-galactosamine 6-phosphate is a member of the chemical class known as Hexoses. These are monosaccharides in which the sugar unit is a hexose. D-Galactosamine 6-phosphate is a metabolite in amino sugar catabolism. The GlcNAc6P deacetylase is an enzyme of the amino sugar catabolic pathway that catalyzes the conversion of the GlcNAc6P into glucosamine 6-phosphate (GlcN6P). (PMID 16630633) Glucosamine 6-phosphate (GlcN-6-P) synthase is an ubiquitous enzyme that catalyses the first committed step in the reaction pathway that leads to formation of uridine 5'-diphospho-N-acetyl-D-glucosamine (UDP-GlcNAc), a precursor of macromolecules that contain amino sugars.
