A non-essential amino acid that is a basic molecule of proteins, and which is an excitatory neurotransmitter like glutamate. Along with glutamate, it is one of the most common neurotransmitters in the brain, some of the others being gamma-amino butyric acid (GABA) and glycine, which are both inhibitory in action. Given that it occurs naturally in sugar beets and sugar cane, it has been suggested that aspartate may provide resistance to fatigue and thus promote endurance, but evidence for this suggestion is not decisive.
