Structural formula: {0} (CAS {1})

Caffeic acid is a hydroxycinnamic acid that is cinnamic acid in which the phenyl ring is substituted by hydroxy groups at positions 3 and 4. It exists in cis and trans forms; the latter is the more common. It has a role as an antioxidant, an EC 3.5.1.98 (histone deacetylase) inhibitor, an EC 1.13.11.34 (arachidonate 5-lipoxygenase) inhibitor, an EC 1.13.11.33 (arachidonate 15-lipoxygenase) inhibitor, an EC 2.5.1.18 (glutathione transferase) inhibitor and a plant metabolite. It is a hydroxycinnamic acid and a member of catechols.
