Question

Differentiate between Globular protein and fibrous protein.

✓

Answer

→ Proteins can be classified into two types on the basis of their molecular shape.
→(a) Fibrous protein compounds:
→When the polypeptide chains run parallel and are held together by hydrogen and disulphide bonds, then fibre- like structure is formed. Such proteins are generally insoluble in water. Some common example are keratin (present in hair, wool, silk) and myosin (present in muscles) etc.
→(b) Globular protein compounds:
→This structures results when the chains of polypeptides coil around to give a spherical shape. These are usually soluble in water. Insulin and albumins are the common examples of globular proteins.
