BOTANY

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: -Peptidoglycan (referred to also as murein) is the common cell wall component of most Gram-positive bacteria (about 30%–70% of the cell walls) and Gram-negative (only a minor component of the cell wall <10%) bacteria.

Detailed explanation-3: -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.
