Biological process

N-acetylglucosamine breakdown, N-acetylglucosamine catabolism, N-acetylglucosamine degradation

The chemical reactions and pathways resulting in the breakdown of N-acetylglucosamine. The D isomer is a common structural unit of glycoproteins in plants, bacteria and animals; it is often the terminal sugar of an oligosaccharide group of a glycoprotein.
