Which of the following is NOT an example of fibrous protein ?

(A)Keratin
(B)Myosin
(C)Collagen
(D)Albumin✓ Correct

Answer: (D)

Solution

Fibrous proteins have polypeptide chains lying parallel and held by hydrogen bonds and disulphide links, giving tough, water-insoluble fibres; keratin, myosin and collagen are of this type. Albumin has its chain coiled into a compact spherical shape that dissolves in water, which makes it a globular protein. Albumin is therefore not a fibrous protein.
