N-Acetyl-L-Glutamic acid is a product of the urea cycle and has been shown to inhibit the activity of enzymes such as ester hydrochloride synthetase, which catalyzes the conversion of arginine and citrulline to ornithine and carbamoyl phosphate. N-Acetylglutamic acid also plays an important role in cellular physiology, such as transcriptional regulation and protein synthesis. Deficiency can lead to glutamate accumulation and neurological disorders such as epilepsy. The biochemical properties of N-acetylglutamic acid are still not well known, but it has been shown to react with ammonia to form glutamine.
