In structural tissues of the fiber and matrix type, proteoglycans frequently occur in the matrix. Peptidoglycan is also involved in binary fission during bacterial cell reproduction. Figure: Peptidoglycan structure: The peptidoglycan layer in the bacterial cell wall is a crystal lattice structure formed from linear chains of two alternating amino sugars, namely N-acetylglucosamine (GlcNAc or NAG) and N-acetylmuramic acid (MurNAc or NAM). Peptidoglycan (PG) is a ubiquitous structural polysaccharide of the bacterial cell wall, essential in preserving cell integrity by withstanding turgor pressure.

• The alternating sugars are connected by a β- (1,4)-glycosidic bond. Peptidoglycan pentapeptide | C20H36N6O8 | CID 4294676 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological Published on Jan 27, 2020. An overview of the components and organization of bacterial peptidoglycan. peptidoglycan structure was proposed by Tipper (21). This structure features a hydrogen bond between the C-6 hydroxyl of NAG and the carbonyl oxygen of the lactyl group in NAM. The separation between these atoms in the 20 conformers of com-pound 1 is 8.2 Å, precluding the presence of this hydrogen bond.
