Abstract
The addition of the organic hydroperoxide, cumene hydroperoxide, to liver microsomes results in the appearance of a transient spectral change associated with cytochrome P-450. In addition, unique electron paramagnetic resonance signals are observed with liver microsomal cytochrome P-450 comparable to signals obtained when peroxides interact with metmyoglobin. It is suggested that higher valence states of cytochrome P-450 may function during the activation of oxygen for the hydroxylation of a variety of xenobiotics.
