Biflavonoids and polyflavonoids are organic compounds containing at least two flavan/flavone units. These units are usually linked through CC or C-O-C bonds. Some examples include C2-O-C3, C2-O-C4, C3'-C3''', and C6-C8''. Catechin-(4alpha->8)-pelargonidin 3'-glucoside is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Catechin-(4alpha->8)-pelargonidin 3'-glucoside can be found in strawberry, which makes catechin-(4alpha->8)-pelargonidin 3'-glucoside a potential biomarker for the consumption of this food product.
