Metabolite Identification
Common Nametrans-2-Methoxycinnamic acid
DescriptionTrans-2-methoxycinnamic acid is a member of the class of compounds known as coumaric acids. Coumaric acids are aromatic compounds containing a cinnamic acid moiety hydroxylated at the C2 (ortho-), C3 (meta-), or C4 (para-) carbon atom of the benzene ring. Trans-2-methoxycinnamic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Trans-2-methoxycinnamic acid can be found in chinese cinnamon, which makes trans-2-methoxycinnamic acid a potential biomarker for the consumption of this food product.
