Affected Organism Humans and other mammals
Indication Used for nutritional supplementation, also for treating dietary shortage or imbalance.
Pharmacology A non-essential amino acid. Asparagine is critical for the production of the body's proteins, enzymes and muscle tissue. Supplements of this amino acid are claimed to balance nervous system function.
Mechanism of action Asparagine, a non-essential amino acid is important in the metabolism of toxic ammonia in the body through the action of asparagine synthase which attaches ammonia to aspartic acid in an amidation reaction. Asparagine is also used as a structural component in many proteins.
