Metabolite Identification
Common NameIcofungipen
DescriptionIcofungipen belongs to the class of organic compounds known as beta amino acids and derivatives. These are amino acids having a (-NH2) group attached to the beta carbon atom. Based on a literature review a significant number of articles have been published on Icofungipen. This compound has been identified in human blood as reported by (PMID: 31557052 ). Icofungipen is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Icofungipen 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.
