Chemical Information
FooDB NameProcyanidin C1
DescriptionProcyanidin C1, also known as cinnamtannin A1 or procyanidol C1, 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''. Procyanidin C1 is an extremely weak basic (essentially neutral) compound (based on its pKa). Procyanidin C1 is found, on average, in the highest concentration within a few different foods, such as chocolates, cocoa powders, and apples and in a lower concentration in kiwis, grape wines, and pears. Procyanidin C1 has also been detected, but not quantified in, several different foods, such as yellow wax beans, banana, lettuces, ceylon cinnamons, and cucurbita (gourd). This could make procyanidin C1 a potential biomarker for the consumption of these foods.
