Oxidation ofL-tyrosine by vanadium (V) in presence of sulphuric acid

摘要

Oxidation ofL-tyrosine with vanadium (V) in sulphuric acid medium at constant ionic strength is first order in oxidant and H+. The order in tyrosine varies from 1 to 0. A mechanism consistent with the kinetic results is proposed in which the rate determining step is the decomposition of the complex formed in the prior equilibrium.
