Chemical Information
FooDB NameProcyanidin C1
DescriptionProcyanidin C1, also known as procyanidin C1 or procyanidin 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 exists as a solid, possibly soluble (in water), and an extremely weak basic (essentially neutral) compound (based on its pKa) molecule. Procyanidin C1 is found , on average, in the highest concentration in a few different foods, such as chocolates, cocoa powders, and apples and in a lower concentration in pears, custard apples, and peach (var.). Procyanidin C1 has also been detected, but not quantified in, several different foods, such as apple ciders, loquats, pepper (c. annuum), green zucchinis, and common wheats. This could make procyanidin C1 a potential biomarker for the consumption of these foods.
