N-Acetylgalactosamine (GalNAc), is an amino sugar derivative of galactose.
In humans it is the terminal carbohydrate forming the antigen of blood group A.[1]
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.
