Abstract

Oxidations of glycine, valine, leucine, alanine and phenylalanine by the title reagent have been performed near their isoelectric pH, at 35 °C. The rate law is-d log[BAB]/dt=k′[Amino acid]x where x is 0.40–0.75. The influence of halide ions, ionic strength, benzene sulfonamide and the dielectric constant of the medium have been studied. Activation parameters have been computed. The rate of oxidation increases in the order: Alanine>phenylalanine>leucine>valine>glycine.

Abstract

Окисление глицина, валина, леуцина, аланина и фенилаланина с помощью заглавного реагента было проведено в близи их изоэлектрической pH при 35 °C. В уравнении скорости-d log[BAB]/dt=k′[аминокислота]x величина х равна 0.40–0.75. Исследовано влияние галидных ионов, ионной силы, сульфонамидбензола и дизлектрической постоянной среды. Параметры активации определяли на ЗВМ. Скоростть окисления увеличивается в порядке: аланин>фенилаланин>леуцин>валин>валин>глицин.
