What is the difference between fibrous protein and globular protein ?
|Fibrous Proteins||Globular Proteins|
|1.||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.|
|2.||They are usually insoluble in water.||They are usually soluble in water.|
|3.||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.|
