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.
