N -acetylmuramic acid (NAM) is a monosaccharide and is therefore a carbohydrate . Its basic structure is an N -acetylglucosamine , i.e. a glucose molecule with an amide residue acetylated at the C2 atom, whichis etherified with lactic acid via its C3 atom.

NAM is important for the structure of murein , an important substance in bacterial cell walls, where it is glycosidically linked to N- acetylglucosamine.
