Abstract
The comparative kinetics of the oxidation of DL-valine and isoleucine by hydrogen peroxide in the presence of ferrous sulphate were studied at different temperatures in the acidic medium. The reaction is first order with respect to ferrous sulphate and amino acids , and zero order with respect to hydrogen peroxide. The reaction rate is higher in case of iso-leucine than that of DL-valine. The reaction mechanism for both the amino acids have been proposed and rate laws derived. The energies of activation were calculated to be 14.70 and 19.04 Kcal mol-' for iso-leusine and DL-valine, respectively .
