Meaning of peptidoglycan
WebJan 22, 2024 · Peptidoglycan is a large polymer made up of sugars and amino acids and is unique to bacteria. The cell walls of gram-positive bacteria are made up of a thick, mesh-like layer of peptidoglycan. Gram-negative bacteria have only a thin layer of peptidoglycan in their cell walls, but they also have an outer membrane containing lipopolysaccharides.
