Fibrous and globular proteins differ mainly in their shape, solubility, and function.
Here’s a explanation:
Fibrous Proteins
- Have a long, thread-like shape.
- Are tough and strong.
- Usually insoluble in water.
- Provide structure and support to cells and tissues.
- Examples: Collagen, Keratin, Elastin.
Globular Proteins
- Have a round or spherical shape.
- Are soft and compact.
- Usually soluble in water.
- Perform specific functions like catalyzing reactions or transport.
- Examples: Enzymes, Hemoglobin, Insulin, Antibodies.
In short:
Fibrous proteins build the body’s structure.
Globular proteins carry out the body’s functions.
