Common NameSpecnuezhenide
Descriptionmethyl 3-ethylidene-4-[2-oxo-2-({3,4,5-trihydroxy-6-[2-(4-hydroxyphenyl)ethoxy]oxan-2-yl}methoxy)ethyl]-2-{[3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy}-3,4-dihydro-2H-pyran-5-carboxylate belongs to the class of organic compounds known as saccharolipids. Saccharolipids are compounds in which fatty acids are linked directly to a sugar backbone, forming structures that are compatible with membrane bilayers. In the saccharolipids, a sugar substitutes for the glycerol backbone that is present in glycerolipids and glycerophospholipids. The most familiar saccharolipids contain an acylated glucosamine. In contrast to others glycolipids, the fatty acid is not glycosidically linked to the sugar moiety. Based on a literature review very few articles have been published on methyl 3-ethylidene-4-[2-oxo-2-({3,4,5-trihydroxy-6-[2-(4-hydroxyphenyl)ethoxy]oxan-2-yl}methoxy)ethyl]-2-{[3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy}-3,4-dihydro-2H-pyran-5-carboxylate. This compound has been identified in human blood as reported by (PMID: 31557052 ). Specnuezhenide is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Specnuezhenide 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.
