Metabolite Identification
Common NameKaempferol 7-arabinoside
DescriptionKaempferol 7-arabinoside is a member of the class of compounds known as flavonoid-7-o-glycosides. Flavonoid-7-o-glycosides are phenolic compounds containing a flavonoid moiety which is O-glycosidically linked to carbohydrate moiety at the C7-position. Kaempferol 7-arabinoside is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Kaempferol 7-arabinoside can be found in ostrich fern and radish, which makes kaempferol 7-arabinoside a potential biomarker for the consumption of these food products.
