Glutamine can exist in either of two enantiomeric forms, L-glutamine and D-glutamine. The L-form is found in nature. Glutamine contains an α-amino group which is in the protonated −NH 3 + form under biological conditions and a carboxylic acid group which is in the deprotonated −COO − form, known as carboxylate, under physiological ...
The adenylation activity is catalyzed by the bifunctional adenylyltransferase/adenylyl removal (AT/AR) enzyme. Glutamine and a regulatory protein called PII act together to stimulate adenylation. [3] This diagram shows the biosynthesis (anabolism) of amino acids glutamate, glutamine, proline, and arginine from the precursor alpha-ketoglutarate.
Glutamine synthetase (GS) (EC 6.3.1.2) [3] is an enzyme that plays an essential role in the metabolism of nitrogen by catalyzing the condensation of glutamate and ammonia to form glutamine: Glutamate + ATP + NH 3 → Glutamine + ADP + phosphate

Glutamic acid ball and stick model spinning. Glutamic acid (symbol Glu or E; [4] known as glutamate in its anionic form) is an α-amino acid that is used by almost all living beings in the biosynthesis of proteins.
Glutamine will be produced because of the introduction of ammonium in the carbon backbone, which can be converted into glutamate by glutamate synthase of another pathway. [ 2 ] These processes are common in plant roots because if the nitrogen deficient conditions exist (with access to ammonium and nitrate ions), there will be a first priority ...
Glutamine is the most abundant amino acid in the plasma and an additional energy source in tumor cells especially when glycolytic energy production is low due to a high amount of the dimeric form of M2-PK. Glutamine and its degradation products glutamate and aspartate are precursors for nucleic acid and serine synthesis.
