Vedclass · Answer

(C) The primary structure of a protein consists of amino acids linked by peptide bonds. In the secondary structure of proteins,the polypeptide chain is folded into specific shapes like $\alpha$-helices or $\beta$-pleated sheets. These shapes are stabilized by hydrogen bonds formed between the carbonyl oxygen $(C=O)$ and the amide hydrogen $(N-H)$ of the peptide backbone. Since the secondary structure is built upon the primary structure,it retains the peptide bonds that link the amino acids together,while hydrogen bonds provide the specific secondary folding. Therefore,both peptide bonds and hydrogen bonds are present in the secondary structure of proteins.
