In papain macromolecules irradiated with γ-rays, fragments with terminal primary amino groups are formed, which appear in FTIR spectra as a broad peak with a maximum at 3440 cm–1, as well as an intense absorption band centred at 1706 cm–1 as a result of valence vibrations of carbonyl groups. The intensity of the absorption bands of the radiolysis products increases linearly with the irradiation dose of papain. At the same time, with increasing irradiation dose, a marked weakening of the intensity of the maxima of the absorption peaks of the peptide bond is observed, which indicates radiation destruction of the main chain of papain.
