Question

A globular protein is

• A. Elastin
• B. Keratin
• C. Albumin
• D. Collagen

Answer 1

The correct option is C Albumin

Globular proteins are spherical in shape. It is characterized by twisted and folded amino acid chain to increase the protein's solubility in water by placing polar groups of atoms at the protein's surface. The polar groups can interact with the neighboring water molecules which further increase the water solubility. The greater water solubility is due to inter-molecular interaction while the globular structure is due to the intramolecular interaction between the amino acids. Albumin is an egg protein which is globular in structure with polar groups placed at the protein surface.

So, the correct answer is option C.
