They are diterpenes or anphiphilic moleculesthat can be bound to the phospholipids membrane receptor andcan act as a kinase protein activator (PKC), involved in the signal</p><p>issionwhich provokes cellular proliferation. They show tox-cal effects even at very low concentration in experimentalls fed with diets containing them. (3) Some other toxic com-ts identied in J. curcas L. are: jatrophine (an alkaloid) ande (a peptidase), both isolated from the latex.
