Explanation:
Detailed explanation-1: -GlcNac is part of the bacterial cell wall, a peptidoglycan, together with units of N-acetylmuramic acid, cross-linked with oligopeptides.
Detailed explanation-2: -N-acetylmuramic acid is a sugar that is present in the bacterial cell wall.
Detailed explanation-3: -N-Acetylmuramic acid (MurNAc) is part of the peptidoglycan polymer of bacterial cell walls.
Detailed explanation-4: -The NAM carries a tetrapeptide of alternating D and L amino acids, including amino acids unique to bacteria, such as diaminopimelic acid.
Detailed explanation-5: -Bacterial cell wall is made up of peptidiglycan which is made of sugar derivatives-N-acetyl glucosamine (NAG) and N-acetyl muramic acid (NAM).
