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


1.
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.


2. It is usually soluble in water, acids, bases and salts.
 


3. They have comparatively stronger intermolecular forces of attraction.


3. They have weak intermolecular hydrogen bonding.


4. Example: Collagen, fibroin, myosin, hair, skin,silk, wool, etc.


4. Egg, albumin, casein of milk, insulin.
