Common NameIsonipecotic acid
Descriptionpiperidine-4-carboxylic acid belongs to the class of organic compounds known as piperidinecarboxylic acids. Piperidinecarboxylic acids are compounds containing a piperidine ring which bears a carboxylic acid group. piperidine-4-carboxylic acid is a very strong basic compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). Isonipecotic acid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Isonipecotic acid 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.
