Metabolite Identification
Common Name8-4'-Dehydrodiferulic acid
Description8-4'-dehydrodiferulic acid belongs to phenylpyruvic acid derivatives class of compounds. Those are compounds containing a phenylpyruvic acid moiety, which consists of a phenyl group substituted at the second position by an pyruvic acid. 8-4'-dehydrodiferulic acid is practically insoluble (in water) and a moderately acidic compound (based on its pKa). 8-4'-dehydrodiferulic acid can be found in a number of food items such as corn, semolina, common wheat, and hard wheat, which makes 8-4'-dehydrodiferulic acid a potential biomarker for the consumption of these food products.
