Question:
The water soluble protein is :
The water soluble protein is :
Show Hint
Remember: "Globular" sounds like "Globe" (spherical) \(\to\) Water-soluble. "Fibrous" sounds like "Fiber" (thread-like) \(\to\) Water-insoluble.

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Proteins are classified into two types based on their molecular shape: Fibrous proteins and Globular proteins.
Step 3: Detailed Explanation:
1. Fibrous Proteins: These consist of linear thread-like molecules that lie side by side to form fibers. They are held together by hydrogen and disulphide bonds. They are insoluble in water. Examples include Keratin (hair, wool), Myosin (muscles), Collagen (connective tissue), and Fibrin (blood clots).
2. Globular Proteins: In these, the polypeptide chain folds around itself to give a spherical shape. The lipophilic (hydrophobic) parts are pushed inside while hydrophilic parts face outside. They are soluble in water. Examples include Insulin and Albumin (egg white).
Step 4: Final Answer:
Among the given options, Albumin is a globular protein and is thus water-soluble.
