Metabolite Identification
Common Name3,4-Dihydroxy-trans-cinnamate
DescriptionCaffeic acid, also known as caffeate, belongs to the class of organic compounds known as hydroxycinnamic acids. Hydroxycinnamic acids are compounds containing an cinnamic acid where the benzene ring is hydroxylated. Caffeic acid exists as a solid, possibly soluble (in water), and an extremely weak basic (essentially neutral) compound (based on its pKa) molecule. Caffeic acid exists in all living species, ranging from bacteria to humans. Caffeic acid is formally rated as a possible carcinogen (by IARC 2B) and is also a potentially toxic compound.
