Abstract

HUO, SHUYING et al. MECHANISTIC INVESTIGATION OF OXIDATION OF SOME AMINO ACIDS BY BIS(DIHYDROGEN TELLURATE)ARGENTATE(III) ION IN ALKALINE MEDIUM: A KINETIC STUDY. J. Chil. Chem. Soc. [online]. 2009, vol.54, n.4, pp.385-390. ISSN 0717-9707.  http://dx.doi.org/10.4067/S0717-97072009000400013.

The oxidation of leucine, isoleucine and valine by bis(dihydrogen tellurate)argentate(III) ion was studied by stopped-flow technique. It was both first order with respect to Ag(III) complex and amino acids. A plausible mechanism was proposed form the kinetics study. And the rate equations derived from mechanism can explain all experimental phenomena. The activation parameters along with the second order rate constants were calculated.

Keywords : Bis(dihydrogen tellurate)argentate(III); amino acid; Kinetics and mechanism; Redox reactions.
