Abstract

The sulfur-containing amino acid methionine, CH3SCH, CH, CHNH,(COOH)(Met), has been found to be easily oxidized by free radicals. 14 It has been shown by radiation chemical studies, for example, that the radical-induced oxidation occurs with absolute rate constants which are practically only controlled by the diffusion of the reactants, eg, k= 2.3 X loio Ml s-', for the reaction. OH+ Met. 2 Reductive degradation is also possible, but takes place with ...
