Assertion : Insulin is water soluble. Reason : Insulin is a globular protein.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Insulin, a globular protein, exhibits water solubility attributed to its three-dimensional folded structure, stabilized by internal hydrogen bonds, facilitating interaction with aqueous environments for biological functionality. So, option (2) is correct.

The one that does not stabilize \(2^{\circ}\) and \(3^{\circ}\) structures of proteins is
1 - O - O - linkage
2 van der Waals forces
3 - S - S - linkage
4 H-bonding.
Explanation:
The main forces which stabilise the secondary and tertiary structures of proteins are hydrogen bonds, disulphide linkages, van der Waals' forces and electrostatic forces of attraction.

Which of the following statement is NOT true about globular proteins?
1 These are soluble in water
2 These are folded to give three dimensional spheroidal shape
3 They have largely \(\alpha\)-helical structure
4 Albumin in egg is an example of globular protein
Explanation:
They are soluble in water and globular proteins results when the polypeptide chains coil around to give 3-D spherical shape. Albumin is an example of globular protein.
