Secondary Accession NumbersNone
Metabolite Identification
Common NameCeramide 1
DescriptionCeramide 1 belongs to the class of organic compounds known as phytoceramides. These are n-acylated 4-hydroxysphinganine. Based on a literature review a significant number of articles have been published on Ceramide 1. This compound has been identified in human blood as reported by (PMID: 31557052 ). Ceramide 1 is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Ceramide 1 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.
