Abstract
The influence of radioprotectors (P) (cysteine, cysteamine) and hemato porphyrin on the yields of malonic dialdehyde and an unidentified carb onyl compound from the radiolysis of 2-deoxy-D-ribose (DR) in aqueous N2O- or air-saturated solutions was studied. The experimental yields ( G) were compared with the calculated (G(c)) ones on the basis of the s tudy of competition between P and DR for the H atoms and OH radicals. The values of G/G(c) < 1 can be explained by the repair of DR via H tr ansfer from P to DR..
