Abstract
Recent studies (1-4) have shown that differences in radiosensitivity of various amino acid residues within proteins irradiated by y-rays in the dry state are small and that there is no selective breakage of sulfur-sulfur bonds or other covalent structures. In irradiated gelatin and in other fibrous proteins (and also in polyamino acids) the main polypeptide chain is broken, but such degradative action is not apparent with globular proteins. This investigation was undertaken to further substantiate the differences in the properties of these two types of proteins after exposure to y-rays in the dry state.
