Question:
What type of compound the Keratin is?
What type of compound the Keratin is?
Show Hint
Keratin forms hair, nails and wool and is insoluble in water.
Updated On: Nov 12, 2026
- globular protein
- vitamins
- fibrous protein
- polysaccharides
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept
Proteins are classified by shape into fibrous proteins (long chains, insoluble in water) and globular proteins (folded and soluble).
Step 2: Keratin
Keratin is found in hair, wool, nails and skin. Its long polypeptide chains lie side by side, held by hydrogen bonds and disulfide bonds.
Step 3: Conclusion
This thread-like structure makes keratin a fibrous protein.
Final Answer:
Keratin is a fibrous protein. \[ \boxed{\text{(C) }\text{fibrous protein}} \]
