 (pĕp′tĭ-dō-glī′kən, -kăn′)
A polymer found in the cell walls of prokaryotes that consists of polysaccharide and peptide chains in a strong molecular network. Also called mucopeptide, murein.

[peptide + glycan, a polysaccharide.]

Cephalosporins cause the breakage of cell wall of bacteria by interacting synthesis of peptidoglycan layer of bacterial cell wall.
The cell wall of Gram-positive cell consists of 90-95% of peptidoglycan. Hydrophobic compounds can penetrate through the cell wall of the Gram-positive bacteria and can act on the cell wall and deeper inside of the cytoplasm while the PVA hydrogel was hydrophilic, the bacterial structures may disrupt and results in the degradation of the cell wall by the actions of the membranes.
The bacterial cell wall consists of peptidoglycan macromolecules, a disaccharide of N-acetylglucosamine and N-acetylmuramic acid, which is present as a linear chair or linked to other substances.
The mechanism is alleged by way of disrupting the Peptidoglycan constituent components on a bacterial cell, so that the layer of the cell wall is not perfectly formed.
In a study, radiation-related harmful effects of 2- (3-aminopropylamino) ethylsulphonyl phosphonic acid (WR-2721) and peptidoglycan (PGN) on the intestines and bone marrow peptidoglycan both as a single agent or a combination therapies.
flexneri changed to squeezed, collapsed, polygon-shaped cocci and varied elongations observed in other bacterial strains, the inhibition of a significant step in peptidoglycan assembly could be connoted as a possible effect of the extract.
The collective action of these three enzymes incorporate DAlanyl-D-Lactate instead of D-Alanyl-D-Alanine into peptidoglycan which prevents the attachment of vancomycin9.
D-alanyl-D-alanine of the elongating peptidoglycan, thereby obstructing the polymerase extending the peptidoglycan backbone and also impedes the cross linking of the growing chain by transpeptidase.
The peptidoglycan-stimulated PBMCs from patients with Behcet's disease who carried rs3804099 TT genotype expressed higher amounts of TLR2 mRNA than those who carried the CC or CT genotypes after stimulation with peptidoglycan (28).
Commercial peptidoglycan preparations are contaminated with superantigen-like activity that stimulates IL-17 production.
rubrum possibly because they were able to penetrate the thin peptidoglycan layer of the fungus with the outer membrane composed of phospholipids and lipopolysaccharides (LPS) of the E.
