Detailed explanation-1: -Murein and pseudomurein are the major cell wall material of bacteria and some methanogenic archaea, respectively. Murein, also called peptidoglycan, is composed of N-acetylmuramic acid and N-acetyl-d-glucosamine (NAG) linked by (1→4) glycosidic bonds.

Detailed explanation-2: -Murein is composed of glycan strands of alternating -1, 4-linked GlcNAc--1, 4-MurNAc disaccharides that are cross-linked by short peptides (72). In E. coli and other gram-negative bacteria, the MurNAc residue at the end of the strand has a 1, 6-anhydro modification (34, 69).

Detailed explanation-3: -The cell wall of most bacteria is made of a polymer called peptidoglycan, which is made of sugars and amino acids.
