which two of the following are the sugar monomers found in peptidoglycan?
□ glucose
□ n - acetylgalactose
□ n - acetylmuramic acid
□ n - acetylglucosamine
□ n - acetylmannose
□ sucrose

Explanation:

Peptidoglycan is a polymer in bacterial cell walls. Its sugar monomers are N - acetylmuramic acid and N - acetylglucosamine. Glucose is a general monosaccharide but not a monomer of peptidoglycan. N - acetylgalactose and N - acetylmannose are not monomers of peptidoglycan. Sucrose is a disaccharide, not a monomer of peptidoglycan.

Answer:

C. N - acetylmuramic acid, D. N - acetylglucosamine
