| Common Name | Nornicotine |

| Description | Nornicotine, also known as (+-)-nornicotine or DL-norcitine, belongs to the class of organic compounds known as pyrrolidinylpyridines. Pyrrolidinylpyridines are compounds containing a pyrrolidinylpyridine ring system, which consists of a pyrrolidine ring linked to a pyridine ring. In humans, nornicotine is involved in the nicotine metabolism pathway. Nornicotine has been detected, but not quantified in, a few different foods, such as anatidaes (Anatidae), chickens (Gallus gallus), and domestic pigs (Sus scrofa domestica). This could make nornicotine a potential biomarker for the consumption of these foods. Nornicotine is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Based on a literature review a small amount of articles have been published on Nornicotine. |
