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).
