Interactions of thiyl free radicals with oxygen: a pulse radiolysis study.
A pulse radiolysis study of glutathione in aqueous solution at pH 5.5 containing N2O/O2 mixtures at various ratios indicates that oxygen rapidly adds to the thiyl glutathione radical yielding aExpand

The inactivation of alcohol dehydrogenase by x-rays and the dose-modifying effect of some added substances.
The inactivation yield of yeast alcohol dehydrogenase in 0.05 M phosphate buffer, pH 7, was found to be 0.14 molecule per 100 eV. The apparent yield was constant in the range 0.1 to 1 mg/ml, showingExpand

Primary and secondary radicals in the radiation-induced inactivation of yeast alcoholdehydrogenase.
SummaryRadiation inactivation of YADH in dilute aqueous solution that does not contain oxygen is due to H atoms and OH radicals, whose inactivating efficiencies are in the ratio 9 : 1. The sameExpand
