Common Name3-Acetamido-5-[acetyl(methyl)amino]-2,4,6-triiodo-N-[(2R,3R,4R,5S,6R)-2,4,5-trihydroxy-6-(hydroxymethyl)oxan-3-yl]benzamide
Description3-Acetamido-5-[acetyl(methyl)amino]-2,4,6-triiodo-N-[(2R,3R,4R,5S,6R)-2,4,5-trihydroxy-6-(hydroxymethyl)oxan-3-yl]benzamide, also known as 3-[(1-hydroxyethylidene)amino]-2,4,6-triiodo-5-(N-methylacetamido)-N-[2,4,5-trihydroxy-6-(hydroxymethyl)oxan-3-yl]benzene-1-carboximidate, belongs to the class of organic compounds known as acylaminosugars. These are organic compounds containing a sugar linked to a chain through N-acyl group. Based on a literature review very few articles have been published on 3-Acetamido-5-[acetyl(methyl)amino]-2,4,6-triiodo-N-[(2R,3R,4R,5S,6R)-2,4,5-trihydroxy-6-(hydroxymethyl)oxan-3-yl]benzamide. This compound has been identified in human blood as reported by (PMID: 31557052 ). 3-acetamido-5-[acetyl(methyl)amino]-2,4,6-triiodo-n-[(2r,3r,4r,5s,6r)-2,4,5-trihydroxy-6-(hydroxymethyl)oxan-3-yl]benzamide is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 3-Acetamido-5-[acetyl(methyl)amino]-2,4,6-triiodo-N-[(2R,3R,4R,5S,6R)-2,4,5-trihydroxy-6-(hydroxymethyl)oxan-3-yl]benzamide 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.
