ODAP is an agonist of the ionotropic AMPA glutamate receptor. It is known to cause neurolathyrism in humans, a motor neuron degenerative disease characterized by degeneration of pyramidal-tract neurons in the spinal cord and in the area of the cortex controlling the legs, resulting in lower-body paralysis. There is not one direct explanation as to how ODAP causes neurolathyrism; however, there has been evidence to support a few biological effects. One reason why the mechanism of … WebNov 1, 1994 · The beta-ODAP content of a batch of dry seed corresponded to 0.74% (w/w) with a relative standard deviation of 2.8%. Thermal treatment of ODAP standards at 80-90 degrees C reduced the response to 62% of that before heating. The decrease is due to beta<-->alpha isomerization, and the experiment thus confirms that the method is …
