Metabolite Identification
Common Name(E)-Squamosamide
Description(E)-Squamosamide belongs to the class of organic compounds known as stilbenes. These are organic compounds containing a 1,2-diphenylethylene moiety. Stilbenes (C6-C2-C6 ) are derived from the common phenylpropene (C6-C3) skeleton building block. The introduction of one or more hydroxyl groups to a phenyl ring lead to stilbenoids (E)-Squamosamide has been detected, but not quantified in, fruits. This could make (e)-squamosamide a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on (E)-Squamosamide.
