Question
What is the difference between fibrous protein and globular protein?
Solution
|
Fibrous Proteins |
Globular Proteins |
|
They are fibre-like structures formed by polypeptide chains. Such proteins are held together by strong hydrogen and disulphide bonds. |
The polypeptide chains in these proteins are folded around themselves, giving these proteins a spherical structure. |
|
They are usually insoluble in water. |
They are usually soluble in water. |
|
They are structural proteins. For example, keratin is present in nails and hair, collagen is present in tendons and myosin is present in muscles. |
They are functional proteins. For example, most enzymes and some hormones like insulin. |
