The increased activities of argininosuccinate synthetase and argininosuccinate lyase suggest the increased and effective recycling of citrulline to arginine in anoxia, making nitric ... arginine at the site of synthesis. Arginine is a semi essential amino acid and in CNS, its availability depends upon: (a) uptake from the circu- lating arginine and (b) recycling of ci...
