Peptidoglycan forms sheets that stiffen the cell walls of bacteria. how is the formation of sheets possible?

Formation of peptide bonds

Explanation:

The structure of peptidoglycan layer found in the cell wall of bacteria consists of linear polymer chains of two alternating amino sugars that are crossed linked by peptide bond. .

The sheet is formed from the cross linkages of the alternating amino-glycan chains by peptide linkages. Hence the word peptidoglycan.

The two amino sugars are N-acetylglucosamine and N-acetylmuramic acid and are linked covalently by β-1,4-glycosidic bond.

Answer is a each strands are joined by peptide bonds.
