Common NameN-Acetylgalactosamine
DescriptionN-Acetylgalactosamine, also known as Tn or alpha-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-Acetylgalactosamine is an extremely weak basic (essentially neutral) compound (based on its pKa). ganglioside GM3 (D18:1/24:1(15Z)) and N-acetylgalactosamine can be biosynthesized from ganglioside GM2 (D18:1/24:0) through the action of the enzyme hexosaminidase a. An N-acetyl-D-galactosamine having alpha-configuration at the anomeric centre. In humans, N-acetylgalactosamine is involved in the metabolic disorder called the g(m2)-gangliosidosis: variant b, tay-sachs disease pathway. Outside of the human body, N-Acetylgalactosamine has been detected, but not quantified in, several different foods, such as common sages, new zealand spinachs, garden onions, malabar plums, and wild rices. This could make N-acetylgalactosamine a potential biomarker for the consumption of these foods.
