Chemical Information
FooDB Nametrans-caffeate
Description3,4-dihydroxycinnamic acid, also known as caffeic acid or trans-caffeate, is a member of the class of compounds known as hydroxycinnamic acids. Hydroxycinnamic acids are compounds containing an cinnamic acid where the benzene ring is hydroxylated. 3,4-dihydroxycinnamic acid is slightly soluble (in water) and a weakly acidic compound (based on its pKa). 3,4-dihydroxycinnamic acid can be found in fats and oils and nuts, which makes 3,4-dihydroxycinnamic acid a potential biomarker for the consumption of these food products. 3,4-dihydroxycinnamic acid exists in all eukaryotes, ranging from yeast to humans. Caffeic acid is an organic compound that is classified as a hydroxycinnamic acid. This yellow solid consists of both phenolic and acrylic functional groups. It is found in all plants because it is a key intermediate in the biosynthesis of lignin, one of the principal components of plant biomass and its residues .
