Metabolite Identification
Common Namen-methylsphingosine
Descriptionn-methylsphingosine belongs to the class of organic compounds known as secondary alcohols. Secondary alcohols are compounds containing a secondary alcohol functional group, with the general structure HOC(R)(R') (R,R'=alkyl, aryl). Based on a literature review a small amount of articles have been published on n-methylsphingosine. This compound has been identified in human blood as reported by (PMID: 31557052 ). N-methylsphingosine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically n-methylsphingosine 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.
