 Title    Gamma-Radiolysis of Aqueous Solution of Proline  
 Abstract    Gamma-radiolysis of 0.05 M aqueous neutral proline solution was investigated. As the main reaction of proline radiolysis in oxygenated solutions, the hydroxylation reactions leading to hydroxyproline formation and the reactions leading to the total destruction of the pyrrolidine ring were shown. In oxygen-free solutions the yield of these reactions decreased; in this medium combination reactions giving rise to higher molecular weight combination products (up to approx. 1500) belong to the most important ones. In addition to radiation-decarboxylation reactions the products of radiation-carboxylation reactions were also detected in the irradiated solution of proline free of oxygen.

 Title    Gamma-Radiolysis of Aqueous Solution of Histidine  
 Abstract    The dependence of Gi(— M) values of histidine on the concentration of irradiated 10-4 —10-1 m solutions, pH and the presence of 0 2 , N20 and sec-butyl alcohol was investigated. In oxygen-free medium the maximum radiation sensitivity of histidine was found at pH 5 — 8 ; in oxygenated solutions it was shifted to the 6 — 11 pH range. The formation of radiation products was also studied. The course of radiation decomposition of histidine depends on the presence of oxygen and on the pH of irradiated solution.
