Explanation:
Detailed explanation-1: -Peptidoglycan (murein) is an essential and specific component of the bacterial cell wall found on the outside of the cytoplasmic membrane of almost all bacteria (Rogers et al., 1980; Park, 1996; Nanninga, 1998; Mengin-Lecreulx & Lemaitre, 2005).
Detailed explanation-2: -The cell wall of bacteria containspeptidoglycan, a substance that does not occur in eukaryotes and which contains D-amino acids and unusual sugars.
Detailed explanation-3: -The peptidoglycan wall (PG) is a unique structure which confers physical strength and defined shape to bacteria. It consists of a net-like macromolecule of peptide interlinked glycan chains overlying the cell membrane.
