Peptidoglycan is a polymer of millions of N-acetylglucosamine (NAG) and N-acetylmuramic acid (NAM) sugars based on glucose molec

ules linked together in long chains cross-braced with four amino acids that link individual polymer chains together in a chain-link fence pattern. Layers of cross-braced NAG and NAM sheets are stacked vertically and held together by proteins with lipid anchors attached to the cell’s cytoplasmic membrane to form a scaffold of sugars and proteins that is able to hold the bacterial cell’s shape, even in response to extreme osmotic pressures. How would you expect a microbiology student to be able to describe the composition of peptidoglycan? What is the composition of the peptidoglycan layers found in the cell wall of bacteria?

Answer:

NAG, short amino acid chains,NAM, lipid and proteins.

Explanation:

The cell wall is the outer covering of the cell lies on the adjacent of the plasma membrane. The cell wall is present in the archaea, bacteria, plants, fungi and absent in the animal cells.

As the inofrmation given in the question, the cellwall consists N-acetylmuramic acid (NAM) and N-acetylglucosamine (NAG). These sugar residues helps n the cross linking with the proteins. The lipids and proteins are the important component of the cell membrane that maintains the shape and function of the cellwall.

Thus, the answer is NAG, short amino acid chains,NAM, lipid and proteins.
