Abstract
Gamma-radiolosis of d-glucose in aqueous solution under anaerobic condition was investigated. d-Glucose was significantly decomposed by action of a hydroxyl radical, a primary radiolytic product of water. Under anaerobic condition, glucose radicals formed by hydrogen abstraction of hydroxyl radical were dehydrated to give deoxygenated sugars, and a part of the radicals followed disproportionation reaction to afford dicarbonyl sugars. Among the products formed through these reactions, 2-deoxy-d-arabinohexono-1,4-lactone (G in N2=0.6, G in N2O=0.8), 3-deoxy-d-erythrohexosulose and other 3-deoxy sugars as deoxygenated compounds, and d-arabinohexosuIose and d-xylohexos-5-ulose as dicarbonyl compounds were identified. From these results, the radiolytic scheme of d-glucose in the absence of oxygen was proposed.This publication has 0 references indexed in Scilit:
