ion-pairstability constantEPRdisproportionationThe decrease in the 1,4-benzosemiquinone (BQ.) disproportionation constant upon addition of either MgCl2 or BaCl2 was used to determine the corresponding semiquinone-M+2ion pair formation constant...
The semiquinone form of Coenzyme Q, originated from its antioxidant action, is readily converted to the oxidized form by another radical: QH·+X·→Q+XH The cell contains several enzymatic systems to reduce oxidized Coenzyme Q (Q) back to its antioxidant form (QH2). Among these are the cyt...

The metabolism of menadione (2-methyl-1,4-naphthoquinone) by isolated hepatocytes. A study of the implications of oxidative stress in intact cells. The cytotoxic effects of many quinones are thought to be mediated through their one-electron reduction to semiquinone radicals, which subsequently enter...
specificity; (3) NQO1 competes with P450 reductase and protects the cells from quinone mutagenicity; and (4) the NQO1 -metabolized quinones (hydroquinones), if not eliminated, cause specific mutations that are not observed with quinones and P450 reductase-activated quinones (semiquinones and ROS)....
