Radiolysis of ethanol and ethanol-water solutions: A tool for studying bioradical reactions

Radiolysis of pure ethanol and ethanol-water solutions is examined in view of its relevance to the study of biological radical mechanisms. On the basis of earlier studies, a consistent reaction scheme is adopted. New data on radical yields are obtained from the radiolysis of dilute solutions of vitamins E and C in these solvents. It is shown that the radiolysis of ethanolic solutions provide an efficient tool to study radical reactions of water-insoluble biomolecules.
