Q. 26

In fibrous protei A. van der Waals forces

B. disulphide linkage

C. electrostatic forces of attraction

D. hydrogen bonds

Answer :

In fibrous proteins, polypeptide chains are held together by disulphide and hydrogen bond in a parallel manner, due to which fibrous like structure is obtained. So options (ii) and (iv) are correct.

Vander Waals forces and electrostatic forces of attraction are not present in the fibrous protein. Therefore, (i) and (iii) are wrong.
