L-Glutamine has been used to study the effects of amino acids in promoting food consumption inDrosophila melanogaster.It has also been used to study non-enzymatic gluconeogenesis.

Glutamine (abbreviated as Gln or Q encoded by the codons CAA and CAG) is an -amino acid that is used in the biosynthesis of proteins. It contains an -amino group (which is in the protonated NH3 form under biological conditions) an -carboxylic acid group (which is in the deprotonated COO form under biological conditions) and a side chain amide which replaces the side chain hydroxyl of glutamic acid with an amine functional group classifying it as a charge neutral polar (at physiological pH) amino acid.
