Question:
Which one of the following is a globular protein?
Which one of the following is a globular protein?
Show Hint
Insulin is globular, while keratin and myosin are fibrous proteins.
Updated On: Oct 1, 2026
- Insulin
- Myosin
- Keratin in hair
- Keratin in wool
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Proteins are grouped into fibrous (long threads, insoluble in water) and globular (folded and roughly spherical, soluble in water).
Step 2: Detailed Explanation:
Fibrous proteins include keratin (in hair, wool, skin, nails), myosin (in muscles) and collagen. Globular proteins include insulin, albumin and haemoglobin.
Step 3: Check the options.
Myosin and both forms of keratin are fibrous. Insulin is globular.
Final Answer:
The globular protein is insulin, option (A). \[ \boxed{\text{Insulin}} \]
