Metabolite Identification
Common Name3-Pyridinecarboxaldehyde
Descriptionpyridine-3-carbaldehyde, also known as nicotinaldehyde, belongs to the class of organic compounds known as pyridine carboxaldehydes. These are aromatic compounds containing a pyridine ring which bears a carboxaldehyde group. Based on a literature review very few articles have been published on pyridine-3-carbaldehyde. This compound has been identified in human blood as reported by (PMID: 31557052 ). 3-pyridinecarboxaldehyde is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 3-Pyridinecarboxaldehyde 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.
