The Chemical Mechanism of The Oxidative Deamination of Amino Acids by Catechol and PolYPHENOLASE

Abstract

The continuous deamination of certain amino acids by the system catecholpolyphenolasetakes place through intensely coloured intermediate compounds.These intermediates are formed by the combination of equimolecular proportionsof o-quinone with amino acids or secondary amines. They are presentedas structural homologues of adrenochrome or hallachrome and probably ofSzent-Gyorgyi's tyrin (1925).
