Abstract
Two alternative specific and very sensitive methods for determination of vinyl epoxide synthetase activity in liver microsomes are described.
Trichloroethylene, which is used as a substrate, is converted into trichloro-ethylene oxide by a hepatic epoxide synthetase. Chloral hydrate, the final rearrangement product of trichloroethylene oxide, is evaluated by electron capture gas chromatography, either after derivatization with pentafluorophenyl-hydrazine or after its conversion into chloroform under alcaline conditions. The kinetic parameters of the epoxidative reaction have been determined on rat hepatic microsomal suspensions.
