Peptidoglycan is a polymer of millions of n-acetylglucosamine (nag) and n-acetylmuramic acid (nam) sugars based on glucose molecules 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? pick the answer that lists the composition of the bacterial cell wall. view available hint(s) pick the answer that lists the
a. composition of the bacterial cell wall.
b. short amino acid chains, nag, nam, and some lipid proteins
c. proteins and sugars
d. nag and nam
e. amino acids, nag, and nam
