Notes:
The kinetics of the oxidation of α-amino acids (glutamic acid and aspartic acid) by alkaline hexacyanoferrate(III) were studied at constant ionic strength and over the temperature range 323-348 K. The rate was dependent on the first power of the concentrations of substrate and oxidant, but was independent of the concentration of alkali in the range studied. The value of kH/kD was in the range 8·1-8·3 for the slow step, indicating the loss of a hydrogen atom from the C—H bond, giving a radical species which was characterized by ESR spectroscopy. The reaction proceeds by way of the α-imino acid, formed in a fast step, which undergoes hydrolysis to give the corresponding α-keto acid.
