Aspartic acid, also known as aspartate, the name of its anion, is one of the 20 natural proteinogenic amino acids which are the building blocks of proteins. As its name indicates, it is the carboxylic acid analog of asparagine. It is non-essential in mammals, and might serve as an excitatory neurotransmitter in the brain. It is also a metabolite in the urea cycle, and participates in gluconeogenesis. IUPAC nomenclature is a systematic way of naming organic chemical compounds as recommended by the International Union of Pure and Applied Chemistry (IUPAC). ...

Aspartic acid has a molecular weight of 133.10, a van der Waals radius of 91 and an isoelectric point of 2.85. The molecular mass of a substance (less accurately called molecular weight and abbreviated as MW) is the mass of one molecule of that substance, relative to the unified atomic mass unit u (equal to 1/12 the mass of one atom of carbon-12). ... Intermolecular forces are electromagnetic forces which act between molecules or between widely separated regions of a macromolecule. ... The isoelectric point (pI) is the pH at which a molecule carries no net electrical charge. ...


This neurotransmitter may provide resistance to fatigue and thus lead to possessing more endurance, although the evidence to support this idea is not strong.

Team may have found key to cell response (729 words)
The aspartate receptor, which has been extensively studied, is a member of a large family of bacterial protein receptors and is similar to mammalian receptors for such things as low-density lipoproteins, insulin, and both epidermal and platelet-derived growth factors.
The sensing domain of the aspartate receptor was revealed to be a dimer, a molecule consisting of two subunits.
Aspartate binds between two alpha helices of one unit and one alpha helix of the other in a highly charged pocket that engulfs almost the entire surface area of the captured molecule.
