L-aspartic acid, with the molecular formula C4H7NO4, is a non-essential, genetically encoded amino acid. It is formed in the organism by transamination from oxaloacetate. The aspartic acid reacts acidically due to its two carboxy groups. In the physiological pH range of the organism it is usually present as a salt - as aspartate. In the urea cycle, L-aspartic acid is enzymatically combined with citrulline by the argininosuccinate synthetase to form argininosuccinate.

Naturally, asparagine acid is found in pulses and asparagus as well as in fish and meat.
