Vedclass · Answer

(B) Peptidoglycan, also known as murein, is a polymer consisting of sugars and amino acids that forms a mesh-like layer outside the plasma membrane of most bacteria, forming the cell wall.It is a heteropolymer (specifically a heteropolysaccharide) because it is composed of two alternating amino sugar molecules, $N$-acetylglucosamine $(NAG)$ and $N$-acetylmuramic acid $(NAM)$, which are linked by $\beta-(1,4)$ glycosidic bonds and cross-linked by short peptide chains.
