Question
Differentiate between globular and fibrous proteins.
✓
Answer
Difference between globular protein and fibrous protein:
|
Fibrous protein
|
Globular protein
|
|
| 1. |
It is a fibre-like structure formed by the polypeptide chain. These proteins are held together by strong hydrogen and disulphide bonds.
|
The polypeptide chain in this protein is folded around itself, giving rise to a spherical Structure.
|
| 2. |
It is usually insoluble in water, but soluble in strong acids and bases.
|
It is usually soluble in water, acids, bases and salts.
|
| 3. |
They have comparatively stronger intermolecular forces of attraction.
|
They have weak intermolecular hydrogen bonding.
|
| 4. |
Example: Collagen, fibroin, myosin, hair, skin,silk, wool, etc.
|
Egg, albumin, casein of milk, insulin.
