Semiquinone Radicals from Oxygenated Polychlorinated Biphenyls: Electron Paramagnetic Resonance Studies
Polychlorinated biphenyls (PCBs) can be oxygenated to form very reactive hydroquinone and quinone products. A guiding hypothesis in the PCB research community is that some of the detrimental health effects of some PCBs are a consequence of these oxygenated forms undergoing one-electron oxidation or reduction, generating semiquinone radicals (SQ (*-)). These radicals can enter into a futile redo...
متن کاملelectron-paramagnetic-resonance studies using oxygen-17
Studies of the effect of substitution with 170 on the e.p.r. spectra at 9 and 35 GHz of Mo(V) in the phosphate complex of sulphite oxidase are reported. Substitution of '7O-enriched water for normal water, for samples of the enzymes reduced by sulphite in the presence of normal phosphate, produced no detectable effect on the e.p.r. signal. If phosphate substituted with 170 was used, coupling du...
متن کاملElectron paramagnetic resonance studies on the ferredoxin from Clostridium pasteurianum.
We have recently demonstrated an EPR signal in spinach ferredoxin on reduction either enzymically or with dithionite (Palmer and Sands, 1966). It is the purpose of this communication to report on the EPR spectrum found in the ferredoxin obtained from the bacterium C. pasteurianum. The ferredoxin was purified by the method of Mortenson (1964) and had an absorbancy ratio 285 rnp; 3QO rnF of 0.82....

متن کاملChlorination increases the persistence of semiquinone free radicals derived from polychlorinated biphenyl hydroquinones and quinones.
Polychlorinated biphenyls (PCBs) comprise a group of persistent organic pollutants that differ significantly in their physicochemical properties, their persistence, and their biological activities. They can be metabolized via hydroxylated and dihydroxylated metabolites to PCB quinone intermediates. We have recently demonstrated that both dihydroxy PCBs and PCB quinones can form semiquinone radi...
