Hydroxycotinine

Description:

Hydroxycotinine is a metabolite of nicotine, primarily formed in the liver through the action of cytochrome P450 enzymes. It is characterized by its chemical structure, which includes a hydroxyl group (-OH) attached to the pyridine ring of cotinine, the primary metabolite of nicotine. Hydroxycotinine is often used as a biomarker for tobacco exposure, as it is more stable and has a longer half-life than nicotine itself. This compound is typically found in biological fluids, such as urine and saliva, making it useful for assessing nicotine consumption in individuals. Hydroxycotinine exhibits moderate water solubility and is generally considered to have low toxicity. Its presence in biological samples can provide insights into smoking habits and the effectiveness of smoking cessation programs. Additionally, research into hydroxycotinine may contribute to understanding the pharmacokinetics of nicotine and its effects on human health.
