Kinetic study of L-lysine and L-arginine by hexacyanoferrate (III) ion in presence of Os (VIII)

Abstract

Amino acids and their metal complexes have vital role in functioning the metabolism of all living system. Amino acids can undergo many types of reactions in acidic as well as in alkaline medium. The reactions of L-lysine and L-arginine amino acids have been selected in alkaline medium for the present study. The kinetics of oxidation of L-lysine and L-arginine by alkaline Os (VIII), which was continuously regenerated by hexacyanoferrate (III) ion, was studied in the 0.01- 0.10 M and 298 K – 318 K temperature range. The rate of reaction was found to be zero with respect to [Fe(CN6)]3- and one with respect to Os (VIII).
