N-Acetylgalactosamine

Wednesday 30 July 2008

N-Acetylgalactosamine is a monosaccharide derivative of galactose.

Function

In humans it is the terminal carbohydrate forming the antigen of blood group A.

It is typically the first monosaccharide that connects serine or threonine in particular forms of protein O-glycosylation.

N-Acetylgalactosamine is necessary for intercellular communication, and is concentrated in sensory nerve structures of both humans and animals.
