Chemical Information
FooDB NameMeloside
DescriptionMeloside, also known as isovitexin 2''-beta-D-O-glucoside or 2'-O-beta-D-glucosylisovitexin, is a member of the class of compounds known as flavonoid c-glycosides. Flavonoid c-glycosides are compounds containing a carbohydrate moiety which is C-glycosidically linked to the 2-phenylchromen-4-one flavonoid backbone. Meloside is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Meloside can be found in muskmelon, which makes meloside a potential biomarker for the consumption of this food product.
