Description
trans-3’-Hydroxycotinine (3HC) is a product of CYP2A6 metabolism of the primary nicotine metabolite, cotinine . Cotinine has a longer metabolic half-life compared to 3HC (16 hours vs. 5 hours). The ratio of 3HC to cotinine, termed the nicotine metabolite ratio, correlates with nicotine clearance from the body and is used as a biomarker of CYP2A6 activity. This measure of nicotine metabolism has been used to study tobacco and secondhand smoke exposure as well as to develop pharmacological intervention strategies for smoking cessation.
