Metabolite Identification
Common NamePavetannin B6
DescriptionPavetannin B6, also known as cinnamtannin D-1, belongs to the class of organic compounds known as biflavonoids and polyflavonoids. These 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''. Pavetannin B6 is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, pavetannin B6 has been detected, but not quantified in, herbs and spices. This could make pavetannin B6 a potential biomarker for the consumption of these foods.
