4 Drug and Medication Information
4.1 Drug Indication

Used for nutritional supplementation, also for treating dietary shortage or imbalance.


5 Pharmacology and Biochemistry
5.1 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.


5.2 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.


Iron absorption in rats was evaluated with concurrent administration of each of 10 amino acid solutions and ascorbic acid. Asparagine, glycine, serine and ascorbic acid caused a statistically significant increase in iron absorption, with greatest effects for asparagine and glycine. No correlations were found between absorption increases and stability constants of the amino acid-iron complex.
