peptidoglycan

[pep″tĭ-do-gli´kan] a glycan (polysaccharide) attached to short cross-linked peptides; found in bacterial cell walls.

pep·ti·do·gly·can

(pep'ti-dō-glī'kan), A compound containing amino acids (or peptides) linked to sugars, with the latter preponderant. Compare: glycopeptide. Synonym(s): mucopeptide (2)

peptidoglycan

(pĕp′tĭ-dō-glī′kən, -kăn′)n. 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.

Compare: glycopeptide

peptidoglycan

a main component of bacterial CELL WALLS. Peptidoglycan consists of molecules of SUGARS: N-acetylglucosamine and N-acetylmuramic acid, linked together in rows (forming the glycan portion of peptidoglycan), and adjacent rows are cross-linked by PEPTIDES (forming the peptide portion of peptidoglycan). Peptidoglycan forms a lattice that surrounds and protects the whole cell. Generally, Gram-positive BACTERIA (see GRAM'S STAIN have many layers of peptidoglycan, forming a thick and rigid layer, while gram-negative bacteria have a thin layer of peptidoglycan.
