DescriptionN-(3-hydroxy-1-{[3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy}octadec-4-en-2-yl)tetracosanimidic acid belongs to the class of organic compounds known as glycosphingolipids. These are sphingolipids containing a saccharide moiety glycosidically attached to the sphingoid base. Although saccharide moieties are mostly O-glycosidically linked to the ceramide moiety, other sphingolipids with glycosidic bonds of other types (e.g. S-,C-, or N-type) has been reported. Based on a literature review very few articles have been published on N-(3-hydroxy-1-{[3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy}octadec-4-en-2-yl)tetracosanimidic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). Beta-galcer is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically beta-GalCer 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.
