Metabolite Identification

Common Name

Bilin

Description

Bilin belongs to the class of organic compounds known as tetrapyrroles and derivatives. These are polycyclic aromatic compounds containing four pyrrole rings joined by one-carbon units linking position 2 of one pyrrole ring to position 5 of the next. Based on a literature review a significant number of articles have been published on Bilin. This compound has been identified in human blood as reported by (PMID: 31557052 ). Bilin is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Bilin 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.
