(a) Interpretation: The a-keratin and hemoglobin should be compared on the basis of secondary structure. Concept Introduction: The primary structure of a protein is the sequence of amino acids. The a-helix and β-sheet structures are the secondary structures. Similarly, tertiary and quaternary structures also have certain weak intermolecular forces. These structures have different intermolecular forces between peptide chains like hydrogen bonds, S-S bonds, etc. which get altered after heating or in the presence of certain chemicals. Hence, these structures get changed during the denaturation of the protein.
