Metabolite Identification
Common NameNicotyrine
DescriptionNicotyrine, also known as beta-nicotyrine, belongs to the class of organic compounds known as pyridines and derivatives. Pyridines and derivatives are compounds containing a pyridine ring, which is a six-member aromatic heterocycle which consists of one nitrogen atom and five carbon atoms. Based on a literature review a significant number of articles have been published on Nicotyrine. This compound has been identified in human blood as reported by (PMID: 31557052 ). Nicotyrine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Nicotyrine is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
