Trans-cinnamic acid, also known as (2e)-3-phenyl-2-propenoic acid or (E)-cinnamate, is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Trans-cinnamic acid is a sweet, balsam, and honey tasting compound and can be found in a number of food items such as maitake, mustard spinach, common wheat, and barley, which makes trans-Cinnamic acid a potential biomarker for the consumption of these food products. Trans-cinnamic acid can be found primarily in saliva. Trans-cinnamic acid exists in all living species, ranging from bacteria to humans. Trans-cinnamic acid is a non-carcinogenic (not listed by IARC) potentially toxic compound. Cinnamic acid is an organic compound with the formula C6H5CHCHCO2H. It is a white crystalline compound that is slightly soluble in water, and freely soluble in many organic solvents. Classified as an unsaturated carboxylic acid, it occurs naturally in a number of plants.
