Kinetics and Mechanism of the Oxidation of Some Amino Acids with Cerium(IV)

Kinetics of oxidation of some amino acids (L-aspartic acid, L-phenyl alanine, L-serine and L-methionine) with cerium(IV) have been studied in HNO₃-HClO₄ medium. Oxidation of L-aspartic acid, L-phenyl alanine and L-serine by cerium(IV) has been found to follow pseudo-first order kinetics and the oxidation of L-methionine has been found to follow second order kinetics. The kinetic experiments have been used for the suggestion of a probable mechanism. The oxidation products were identified as corresponding aldehydes, ammonia and carbon dioxide.
