Effects of resorcinol (or p-hydroquinone) on the ESR peak height of the control reaction mixture with 1 mM catechol. Effects of resorcinol (or p-hydroquinone) on the ESR peak height of the control reaction mixture with 1 mM catechol were examined. The reaction and ESR conditions were as described in materials and methods section. In the control reaction mixture, there were 50 mM phosphate buffer (pH 7.4), 0.1 M 4-POBN, 0.89 mM linoleic acid, 0.38 M acetonitrile and 20 µM FeCl₃. A, control reaction mixture with 1 mM catechol. B, control reaction mixture with 1 mM catechol in the presence of 1 mM resorcinol. C, control reaction mixture with 1 mM catechol in the presence of 1 mM p-hydroquinone.
