What is hepatic detoxification?

Hepatic detoxification is the liver’s process of neutralizing and removing toxins, especially drugs and poisons, by enzymatic modifications that render them more water-soluble for excretion. This happens mainly in two phases: Phase I reactions (oxidation, reduction, or hydrolysis) introduce or expose functional groups, often via cytochrome P450 enzymes; Phase II reactions (conjugation) attach groups like glucuronide, sulfate, or glutathione to increase solubility. While the liver does metabolize drugs and poisons, detoxification specifically describes this elimination-friendly modification of lipophilic compounds. Synthesis of bile and glycogen storage are distinct liver functions and do not define detoxification.
