Cytochrome P450 System

Meaning

A complex superfamily of enzymes, predominantly located in the liver and intestinal cells, that plays a crucial role in the metabolism and detoxification of both endogenous compounds and exogenous substances, including pharmaceutical agents and environmental toxins. This enzymatic system is central to Phase I biotransformation, converting lipophilic compounds into more polar metabolites for easier excretion. Genetic polymorphisms within this system can significantly alter an individual’s drug response and hormone clearance rates, which is a key consideration in personalized medicine and hormone therapy.
