Radiation-Chemical Oxidation of Peptides in the Solid State

Warren M. Garrison 1, Michael E. Jayko 1, and Winifred Bennett-Corniea 1

Gamma-ray irradiation of polypeptides as highly dispersed fluffs under oxygen leads to chemical degradation of the peptide bond with the remarkably high oxygen consumption of about one molecule per 2 ev of absorbed energy. A radical chain mechanism appears to be involved, and there is evidence that excited states of the polypeptide aggregate undergo chemical quenching by molecular oxygen.
