Muramic acid is an amino sugar acid. In terms of chemical composition, it is the ether of lactic acid and glucosamine. It occurs naturally as N-acetylmuramic acid in peptidoglycan, whose primary function is a structural component of many typical bacterial cell walls.[1]


Chlamydia bacterial species notably lack muramic acid in their cell wall, thus do not gram stain.
