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. |
