Chemical Information
FooDB Nametrans-Caffeic acid
Description3,4-Dihydroxy-trans-cinnamate, also known as trans-Caffeate, is a polyphenol present in normal human urine positively correlated to coffee consumption and influenced by the dietary intake of diverse types of food (PMID:16870009). trans-Caffeic acid is found in many foods, some of which are flaxseed, cereal and cereal products, common grape, fruits, and common sage. It is also found in wine and coffee in free and conjugated forms.
