Common NameC16-Ceramide
DescriptionN-Palmitoylsphingosine belongs to the class of organic compounds known as ceramides. These are lipid molecules containing a sphingosine in which the amine group is linked to a fatty acid. Based on a literature review a significant number of articles have been published on N-Palmitoylsphingosine. This compound has been identified in human blood as reported by (PMID: 31557052 ). C16-ceramide is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically C16-Ceramide 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.
