The rigid layer of bacterial cell walls, composed of alternating sugar units, N-acetyl glucosamine and muramic acid, cross-linked by short peptides.
(= murein) Cross-linked polysaccharide-peptide complex of indefinite size found in the inner cell wall of all bacteria (50% of the wall in Gram negative, 10% in Gram positive). Consists of chains of approximately 20 residues of b (1-4)-linked N-acetyl glucosamine and N-acetyl muramic acid cross-linked by small peptides (4-10 residues).
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 all bacteria (except Mycoplasma), forming the cell wall. The sugar component consists of alternating residues of β-(1,4) linked N-acetylglucosamine and N-acetylmuramic acid. Attached to the N-acetylmur...Found on http://en.wikipedia.org/wiki/Peptidoglycan

A cross-linked complex of polysaccharides and peptides found in the cell walls of bacteria. Gram-positive bacteria (so-called because they color violet when treated appropriately with Gram stain) have a thick layer of a peptidoglycan (or murein), the form of which determines the organism's shape ...Found on http://www.daviddarling.info/encyclopedia/P/peptidoglycan.html
