N -acetylgalactosamine is the common name for 2-acetylamino-2-deoxy- D -galactose, a derivative of galactose or galactosamine .
It serves as a building block for the construction of glycolipids (e.g. gangliosides ) and glycoproteins of the cell membrane as well as for hyaluronic acid and other mucopolysaccharide proteins .
Blood group antigen A contains N- acetylgalactosamine, blood group antigen B contains galactose instead and blood group 0 lacks this sugar residue.
