L-Glutamic acid (Glu) is accepted as the major excitatory neurotransmitter in the nervous system, although other acidic amino acids such as L-aspartic acid and L-homocysteic acid may also participate (1). Nevertheless, ongoing research reveals that the functions of Glu are much more diverse and comp ...
