Metabolite Identification
Common NameN-Acetyl-D-Glucosamine 6-Phosphate
DescriptionN-Acetyl-D-Glucosamine 6-Phosphate, also known as N-acetyl-D-glucosamine-6-p or GLCNAC6P, belongs to the class of organic compounds known as acylaminosugars. These are organic compounds containing a sugar linked to a chain through N-acyl group. N-Acetyl-D-Glucosamine 6-Phosphate is an extremely weak basic (essentially neutral) compound (based on its pKa). N-Acetyl-D-Glucosamine 6-Phosphate exists in all living species, ranging from bacteria to humans. Within humans, N-acetyl-D-glucosamine 6-phosphate participates in a number of enzymatic reactions. In particular, N-acetyl-D-glucosamine 6-phosphate can be biosynthesized from N-acetyl-D-glucosamine; which is mediated by the enzyme N-acetyl-D-glucosamine kinase. In addition, N-acetyl-D-glucosamine 6-phosphate can be converted into glucosamine 6-phosphate and acetic acid through its interaction with the enzyme putative N-acetylglucosamine-6-phosphate deacetylase. In humans, N-acetyl-D-glucosamine 6-phosphate is involved in the metabolic disorder called the salla disease/infantile sialic acid storage disease pathway.
