Description

Nicotine results in many metabolites after metabolization in the liver.

Nicotine is the main factor behind smoking addiction and nicotine supplements have been used to stop smoking.

Nicotine metabolized by several enzymes in the liver such as the CYP2A6 enzyme. CYP2A6 is a xenobiotic (xenos = foreigner bios = life) metabolizer.

How well nicotine can be metabolized by the human body is not standard and depends on racial, sex, genetic and environmental factors.
