Concept explainers
(a)
Interpretation:
The function or biological activity of collagen in the body should be determined.
Concept Introduction:
The primary structure of protein is the sequence of amino acids. The a-helix and β-sheet structure 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 denaturation of protein.
(b)
Interpretation:
The function or biological activity of hemoglobin in the body should be determined.
Concept Introduction:
The primary structure of protein is the sequence of amino acids. The a-helix and β-sheet structure are the secondary structures.

(c)
Interpretation:
The function or biological activity of vasopressin in the body should be determined.

(e)
Interpretation:
