Description générale

Caffeic acid is an antioxidant and the major hydroxycinnamic acid present in wine. It contains a catechol group with an α,β-unsaturated carboxylic acid chain with hepatoprotective properties.

Application

Caffeic acid may be used as an electrocatalysis mediator in voltammetric determination of cysteamine (CA) in an aqueous buffer solution.

Actions biochimiques/physiologiques

A natural dietary phenolic compound found in plants that is an anti-oxidant. Inhibits the synthesis of leukotrienes that are involved in immunoregulation, inflammation and allergy. Inhibits Cu2+-induced LDL oxidation.
