By alkalis they are transformed into stereo-isomers, the a-acid giving 7 -truxillic acid, and the, 3-acid S-truxillic acid.
The " structure theory " (or the mode of linking of the atoms) of carbon compounds, founded by Butlerow, Kekule and Couper and, at a later date, marvellously enhanced by the doctrine of stereo-isomerism, due to J.
