Metabolite Identification
Common NameCatechin 7-xyloside
DescriptionCatechin 7-xyloside 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. Catechin 7-xyloside is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Catechin 7-xyloside can be found in common hazelnut, which makes catechin 7-xyloside a potential biomarker for the consumption of this food product.
