L-Aspartic acid 56-84-8 is one of the two main ingredients of the artificial sweetener aspartame, along with L-phenylalanine. Aspartate is non-essential in mammals, being produced from oxaloacetate by transamination. It can also be generated from ornithine and citrulline in the urea cycle. In plants and microorganisms, aspartate is the precursor to several amino acids, including four that are essential for humans: methionine, threonine, isoleucine, and lysine.
