Identify the bonds that connect the protein structures in a pleated sheet.

a. sulfide linkages.

b. glycosidic linkages.

c. hydrogen bonds ester.

d. linkages peptide bonds

The correct answer will be option-C

Explanation:

The beta-pleated sheet is the secondary structure formed by multiple strands of polypeptide in antiparallel, parallel or mixed direction.

The antiparallel strands of the polypeptides are connected to each other through hydrogen bonding between the CO group of one strand to the NH group of another strand.

Since hydrogen bonds stabilize the two strands of polypeptides in beta-pleated sheet, therefore, the hydrogen bond is the correct answer.
