1.Performance and use
L-Aspartic acid is used as an electrolyte supplement in amino acid infusion, inorganic ion supplements such as potassium and calcium, and fatigue recovery agents.
L-Aspartic acid can be used as ammonia detoxifier, liver function promoter, fatigue recovery agent and other pharmaceuticals, can be made of sodium L-aspartate food additives and a variety of cool drinks additives, but also as a biochemical reagent, culture medium and intermediates of organic synthesis.
