Description
trans-Cinnamic acid, also known as (e)-cinnamic acid or phenylacrylic acid, belongs to the class of organic compounds known as cinnamic acids. These are organic aromatic compounds containing a benzene and a carboxylic acid group forming 3-phenylprop-2-enoic acid. trans-Cinnamic acid exists in all living species, ranging from bacteria to humans. trans-Cinnamic acid is a sweet, balsam, and cinnamon tasting compound. Outside of the human body, trans-Cinnamic acid is found, on average, in the highest concentration within a few different foods, such as chinese cinnamons, olives, and lingonberries and in a lower concentration in redcurrants, red raspberries, and corianders. trans-Cinnamic acid has also been detected, but not quantified in several different foods, such as common oregano, pepper (spice), fennels, pomegranates, and european cranberries. This could make trans-cinnamic acid a potential biomarker for the consumption of these foods. Cinnamic acid has been shown to be a microbial metabolite; it can be found in Alcaligenes, Brevibacterium, Cellulomonas, and Pseudomonas (PMID:16349793). trans-Cinnamic acid is a potentially toxic compound.
