Argininosuccinic acid
Overview
Arginosuccinic acid is a chemical compound that belongs to the class of the amino acids.
Reactions
Some cells synthesize it from citrulline, 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 also forms Fumarate in the Citric Acid Cycle, via argininosuccinate lyase.
