Common Name | 2-Octadecanone, 3-hydroxy- |
---|
Description | 2-Octadecanone, 3-hydroxy-, also known as 3-hydroxy-octadecane-2-one or acyloin, belongs to the class of organic compounds known as long-chain fatty alcohols. These are fatty alcohols that have an aliphatic tail of 13 to 21 carbon atoms. Based on a literature review very few articles have been published on 2-Octadecanone, 3-hydroxy-. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2-octadecanone, 3-hydroxy- is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2-Octadecanone, 3-hydroxy- 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. |
