Application

L-asparagine has been used:
  • to identify and quantify free amino acids released upon oxidation of proteins and peptides by hydroxyl radicals
  • to study the effects of amino acids in promoting food consumption in Drosophila melanogaster
  • to study non-enzymatic gluconeogenesis

Biochem/physiol Actions

L-asparagine is an uncharged derivative of aspartate. It possesses a polar side chain and is a non-essential amino acid.
