Aspartate is ubiquitously present in biosynthesis. It is the synthetic precursor of lysine, threonine, isoleucine, methionine and other amino acids and purine and pyrimidine bases in organisms. It can be used as the carrier of K+ and Mg2+ ions to deliver electrolytes to the myocardium, thereby improving myocardial contractile function and reducing oxygen consumption. It participates in the cycle of ornithine, promotes the production of urea from ammonia and carbon dioxide, reduces the amount of nitrogen and carbon dioxide in the blood, enhances liver function, and relieves fatigue.
