Detailed explanation-1: -The bacterial cell wall consists of peptidoglycan, an essential protective barrier for bacterial cells that encapsulates the cytoplasmic membrane of both Gram-positive and Gram-negative bacterial cells. Peptidoglycan is a rigid, highly conserved, complex structure of polymeric carbohydrates and amino acids.
Detailed explanation-2: -Abstract. The peptidoglycan (murein) sacculus is a unique and essential structural element in the cell wall of most bacteria. Made of glycan strands cross-linked by short peptides, the sacculus forms a closed, bag-shaped structure surrounding the cytoplasmic membrane.
Detailed explanation-3: -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-4: -Peptidoglycan is responsible for the osmotic stability by encasing the cytoplasmic membrane of most bacteria. It is a unique, net-like polymer made of glycan strands which are cross-linked by unusual peptides.
Detailed explanation-5: -The basic structure of peptidoglycan (PGN) contains a carbohydrate backbone of alternating units of N-acetylglucosamine (GlcNAc) and N-acetylmuramic acid, with the N-acetylmuramic acid residues cross-linked to peptides.
