Argininosuccinic acid is a chemical compound that is a basic amino acid.

Reactions

Some cells synthesize argininosuccinic acid from citrulline and aspartic acid and use it as a precursor for arginine in the urea cycle or citrulline-NO cycle. The enzyme that catalyzes the reaction is argininosuccinate synthetase.

Argininosuccinic acid is a precursor to fumarate in the citric acid cycle via argininosuccinate lyase.
