MeSH Heading: Metabolic Detoxication, Phase I
Tree Number(s): G03.171.450.500; G03.787.225.450.500; G07.690.725.225.450.500
Unique ID: D050216
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D050216
Scope Note: Functionalization of exogenous substances to prepare them for conjugation in PHASE II DETOXIFICATION. Phase I enzymes include CYTOCHROME P450 enzymes and some OXIDOREDUCTASES. Excess induction of phase I over phase II detoxification leads to higher levels of FREE RADICALS that can induce CANCER and other cell damage. Induction or antagonism of phase I detoxication is the basis of a number of DRUG INTERACTIONS.
