The oxidation of three α-amino acids by permanganate under neutral conditions has been studied at various temperatures. The use of Exner's statistical method shows no existence of an isokinetic relation in the heterogeneous process but for the homogeneous process such a relation has been found. Moreover, the existence of linear free energy relations was confirmed for the homogeneous process.
