Metabolite Identification

Common Name

4,4'-Bipyridine

Description

4,4'-bipyridine, also known as 4,4'-bpy, belongs to the class of organic compounds known as bipyridines and oligopyridines. These are organic compounds containing two pyridine rings linked to each other. Based on a literature review a significant number of articles have been published on 4,4'-bipyridine. This compound has been identified in human blood as reported by (PMID: 31557052 ). 4,4'-bipyridine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 4,4'-Bipyridine 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.
