Concept explainers
(a)
Interpretation:
The collagen and myoglobin should be compared on the basis of secondary structure.
Concept Introduction:
The primary structure of the 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.
(b)
Interpretation:
Collagen and myoglobin should be compared on the basis of water solubility.

(c)
Interpretation:
The collagen and myoglobin should be compared on the basis of function.

Interpretation:
The collagen and myoglobin should be compared on the basis of location in the body.
