Common_NameHydroxycotinine
DescriptionQuantitatively, the most important metabolite of nicotine in most mammalian species is cotinine. In humans, about 70 to 80% of nicotine is converted to cotinine. 3-Hydroxycotinine (3HC) is the main nicotine metabolite detected in smokers urine. It is also excreted as a glucuronide conjugate (3HC-Gluc). 3HC and 3HC-Gluc account for 40-60% of the nicotine dose in urine.
