What has a structure resembling diferulic acid and is bright yellow?
Diferulic acids Diferulic acids (also known as dehydrodiferulic acids) are organic compounds that have the general chemical formula CHO, they are formed by dimerisation of ferulic acid. Curcumin and curcuminoids, though having a structure resembling diferulic acids', are not formed that way but through a condensation process. Just as ferulic acid is not the proper IUPAC name, the diferulic acids also tend to have trivial names that are more commonly used than the correct IUPAC name. Diferulic acids are found in plant cell walls, particularly those of grasses.
