Problem 14

Background and context

Peptidoglycan is the polymer of sugar and amino acids which are arranged in a mesh-like fashion and make an important structural supportive structure outside the cell membrane called the cell wall. It is made up of sugars: N- acetylglucosamine and N-acetylmuramic acid, which are cross-linked with peptide chains and form the mesh of 3D form. In the case of pseudopeptidoglycan or false peptidoglycan layer, the mesh is made up of N-acetylglucosamine and N-acetyltalosaminuronic acid sugar moiety.
