描述
N-acetylgalactosamine, also known as alpha-galnac or tn, is a member of the class of compounds known as N-acyl-alpha-hexosamines. N-acyl-alpha-hexosamines are carbohydrate derivatives containing a hexose moiety in which the oxygen atom is replaced by an n-acyl group. N-acetylgalactosamine is soluble (in water) and a very weakly acidic compound (based on its pKa). N-acetylgalactosamine can be found in a number of food items such as colorado pinyon, common bean, mulberry, and jostaberry, which makes N-acetylgalactosamine a potential biomarker for the consumption of these food products. N-acetylgalactosamine can be found primarily in feces and saliva, as well as throughout most human tissues. N-Acetylgalactosamine (GalNAc), is an amino sugar derivative of galactose .
