Metabolite Identification
Common NameN-Acetyl-b-D-galactosamine
DescriptionN-Acetyl-b-D-galactosamine, also known as beta-galnac or β-galnac, belongs to the class of organic compounds known as n-acyl-alpha-hexosamines. These are carbohydrate derivatives containing a hexose moiety in which the oxygen atom is replaced by an n-acyl group. N-Acetyl-b-D-galactosamine is an extremely weak basic (essentially neutral) compound (based on its pKa). N-Acetyl-b-D-galactosamine exists in all living organisms, ranging from bacteria to humans.
