in general, peptidoglycan is composed of ______.
□ amino acids
□ lipids
□ sugars
□ nucleotides

Explanation:

Peptidoglycan is a polymer. Its structure consists of glycan chains (made of sugars, specifically N - acetylglucosamine and N - acetylmuramic acid) cross - linked by peptide bridges. These peptide bridges are made up of amino acids. Lipids are not a component of peptidoglycan, and nucleotides are the building blocks of nucleic acids, not peptidoglycan. So the components of peptidoglycan are amino acids and sugars.

Answer:

A. amino acids, C. sugars
