Peptidoglycan is a structural component of the cell wall and membrane. It is a polysaccharide found only in bacterial species. Thus, the statement is true.
Peptidoglycan, also called murein, is an example of a polysaccharide that is a hard and rigid coating that surrounds the cell wall and plasma membrane. It provides structural support and protection from osmotic and turgor pressure in a bacterial cell.
It is a characteristic of the bacterial cell and consists of N-acetylglucosamine (NAG) and N-acetylmuramic acid (NAM). It plays an important role in the protection of bacterial cells and aids in their survival in environmental stress.
