Common NameLewis X antigen
DescriptionN-(2-{[3,5-dihydroxy-2-(hydroxymethyl)-6-{[4,5,6-trihydroxy-2-(hydroxymethyl)oxan-3-yl]oxy}oxan-4-yl]oxy}-6-(hydroxymethyl)-5-{[3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy}-4-[(3,4,5-trihydroxy-6-methyloxan-2-yl)oxy]oxan-3-yl)ethanimidic acid belongs to the class of organic compounds known as oligosaccharides. These are carbohydrates made up of 3 to 10 monosaccharide units linked to each other through glycosidic bonds. Based on a literature review very few articles have been published on N-(2-{[3,5-dihydroxy-2-(hydroxymethyl)-6-{[4,5,6-trihydroxy-2-(hydroxymethyl)oxan-3-yl]oxy}oxan-4-yl]oxy}-6-(hydroxymethyl)-5-{[3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy}-4-[(3,4,5-trihydroxy-6-methyloxan-2-yl)oxy]oxan-3-yl)ethanimidic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). Lewis x antigen is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Lewis X antigen 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.
