Metabolite Identification
Common NameBarban
DescriptionBarban, also known as carbyne, belongs to the class of organic compounds known as phenylcarbamic acid esters. These are ester derivatives of phenylcarbamic acids. Based on a literature review a significant number of articles have been published on Barban. This compound has been identified in human blood as reported by (PMID: 31557052 ). Barban is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Barban 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.
