Metabolite Identification
Common Name9-Octadecenamide
Description9-Octadecenamide, also known as oleamide or oleic acid amide, belongs to the class of organic compounds known as fatty amides. These are carboxylic acid amide derivatives of fatty acids, that are formed from a fatty acid and an amine. Based on a literature review very few articles have been published on 9-Octadecenamide. This compound has been identified in human blood as reported by (PMID: 31557052 ). 9-octadecenamide is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 9-Octadecenamide 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.
