Biological Activity
| Toxicity/Toxicokinetics |
Toxicity Summary 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. |
