Gamma radiolysis of glucose and relative compounds: a spin-trapping study

Creators

Description

Gamma-induced radicals in polycrystalline α-D-glucose, 1-methyl α D glucose and maltose were trapped with a water-ethanol solution of 2-nitroso-2-methylpropane. Respectively 9, 7 and 9 long-lived nitroxide spin adducts were evidenced by combining electron spin resonance and high performance liquid chromatography experiments. A proposed mechanism from spin trapping assays is compared to the ones postulated from other ESR and radio-chemical studies

Abstract (French)

Les radicaux formes par irradiation gamma dans l' α-glucose, le methyl 1α-glucose et le maltose polycristallins sont pieges par une solution hydro-alcoolique de nitroso-2 methyl-2 propane. 9, 7 et 9 adduits nitroxydes stables sont respectivement mis en evidence en combinant des experiences de resonance paramagnetique electronique et de chromatographie liquide haute performance. Un mecanisme est propose a partir de ces etudes de piegeage de spin et est compare a ceux avances apres d'autres travaux radiochimiques ou de RPE
