title: The physiological and pharmacological roles of cytochrome P450 isoenzymes.
abstract: The cytochrome P450 isoenzymes are a superfamily of haemoprotein enzymes that catalyse the metabolism of a large number of endogenous and exogenous compounds. Recently, the cytochrome isoenzymes have been shown to be important in the synthesis of steroid hormones and bile acids, the arachidonic acid cascade and in central nervous function. These enzymes are a major determinant of the pharmacokinetic behaviour of numerous drugs. Furthermore, alterations in cytochrome P450 activity have been implicated in some diseases.
