The effect of prior thermal denaturation on the electron paramagnetic resonance spectra of irradiated dry preparations of oxyhemoglobin, pepsin, ichthyocol, and casein was studied. As a result of such denaturation, post- irradiation doublet splitting (the same as found with crystalline glycylglycine) is observed in the spectra. Denaturation increases the radiation-induced free radical concentrations by several hundred times. The observed effects are given a structural interpretation. (auth)
