Radiation chemistry of carbohydrates. Part V. γ-Radiolysis of scyllo-inositol in deoxygenated and oxygenated aqueous solution

Abstract

scyllo-Inositol has been γ-irradiated in deoxygenated and oxygenated N₂O-saturated aqueous solutions. The products have been identified and their G values determined. In oxygen free solutions at 0° the following products have been found: (G values in parentheses): scyllo-myo-inosose (3.0), myo-inositol (2.1), deoxyinosose (1.1), and H₂O₂(0.45). Except for H₂O₂, the G values depend on dose rate and temperature. A reaction scheme is given which accounts for these dependences. In oxygenated solution only scyllo-myo-inosose (6.15) and H₂O₂(3.9) were observed. The G values did not vary much with temperature.
