Incorporation of an oxygen atom into the phenolic product during the oxidation of oMitoPhB(OH)2 by H2O2.
a, chemical structures of the products. b, online mass spectra of the products. c, LC-MS/MS traces of the phenolic products containing 16O (left panel) or 18O (right panel). LC-MS/MS analyses were performed after incubation (20 min) of oMitoPhB(OH)2 (20 μm) alone (control), with H216O2 (10 mm) in H218O (90%), or with H218O2 (10 mm) in H216O.
