Q and A: about health and research

Cytochrome P450 (CYP450) is a large and diverse family of enzymes that play a vital role in the metabolism of numerous substances within the body. These enzymes are primarily located in the liver but are also present in other tissues, including the intestines, lungs, and kidneys. They are involved in the metabolism of both endogenous (originating within the body) and exogenous (originating outside the body) compounds, making them essential for maintaining physiological balance and protecting the body from potentially harmful substances. Key Functions of Cytochrome P450 Enzymes Drug Metabolism : One of the primary functions of CYP450 enzymes is the metabolism of drugs and medications. These enzymes chemically modify drugs to make them more water-soluble, thereby facilitating their elimination from the body. This process often involves complex reactions such as oxidation, reduction, hydrolysis, and conjugation. For instance, the CYP3A4 enzyme, one of the most abundant CYP450 enzymes in ...
