Solution
The correct option is A STATEMENT-1 is True, STATEMENT-2 is True; STATEMENT-2 is a correct explanation for STATEMENT-1
Option (A) is correct.
Amino acids are generally obtained by acid or enzyme hydrolysis of proteins but not by alkaline hydrolysis. An alkali racemises amino acids. Different amino acids racemise at different rates. The degree of racemisation undergone varies from protein to protein, but the relative order of the degree of racemisation of the individual amino acids within proteins shows a high level of similarity. The principal factors influencing racemisation are the pH of the medium, heat treatment, the duration of the application of alkaline treatment and the structure of the respective amino acids.
