Metabolite Identification
Common Nametrans-Cinnamic acid
Descriptiontrans-Cinnamic acid, also known as (2E)-3-phenylacrylate or (e)-cinnamate, 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 as a solid, possibly soluble (in water), and a weakly acidic compound (based on its pKa) molecule. trans-Cinnamic acid exists in all living species, ranging from bacteria to humans. trans-Cinnamic acid is a potentially toxic compound.
