LOW-TEMPERATURE RADIOLYSIS OF GLYCEROL-1-PHOSPHATE .1. THE ROLE OF TRAPPED AND DRY ELECTRONS, HYDROGEN-ATOMS, AND HYDROXYL RADICALS IN GLYCEROL-1-PHOSPHATE DEGRADATION

A comparative EPR study on the behavior of H atoms and OH radicals tra pped at 77 K in glassy 6 mol/l H3PO4 + 0.1 mol/l glycerol-1-phosphate solutions in the postradiation period (after two hours to one year) an d upon thermal annealing irradiated samples at 105-130 K showed that t he primary glycerol-1-phosphate radicals were formed by H and OH attac k at all available H-C positions of the three carbon atoms. Neither dr y nor trapped electrons react with glycerol phosphate during irradiati on.
