Oxene transfer, electron abstraction, and cooxidation in the epoxidation of stilbene and 7,8-dihydroxy-7,8-dihydrobenzo[a]pyrene by hemoglobin

Hemoglobin plus H2O2 oxidizes trans-stilbene to trans-stilbene oxide, cis-stilbene to cis- and trans-stilbene oxide, and trans-7,8-dihydroxy-7,8-dihydrobenzo[a]pyrene to anti-trans-7,8,9,10-tetrahydroxy-7,8,9,10-tetrahydrobenzo[a]pyrene. Oxidation of cis- and trans-stilbene to the corresponding cis-...
