Quizplus · Accepted Answer

Peptidoglycan is a component of bacterial cell walls and is made up of parallel strands of alternating N-acetylglucosamine and N-acetylmuramic acid molecules, joined together by peptide bonds. Cellulose is made up of parallel strands of glucose molecules linked by beta-1,4 glycosidic bonds, but not peptide bonds. Starch and glycogen are both composed of glucose molecules linked by alpha-1,4 glycosidic bonds, but do not contain peptide bonds.
