glutamine /glu·ta·mine/ (glldbomact´ah-mēn) the monoamide of glutamic acid, a nonessential amino acid occurring in proteins; it is an important carrier of urinary ammonia and is broken down in the kidney by the enzyme glutaminase. Symbols Gln and Q.
glutamine (Gln) 
glutamine (glōōˑ·t
·mēn),
glu·ta·mine (gl  t -m n )n. Abbr. Glu A nonessential amino acid that occurs widely in proteins and blood and other tissue and is metabolized to yield urinary ammonia. Also called glutaminic acid. |
glutamine (Gln)
[glo̅o̅′təmēn]
Etymology: L, gluten + amine, ammonia
a nonessential amino acid found in the juices of many plants and in many proteins in the body. It functions as an amino donor for many reactions. It is also a nontoxic transport for ammonia because it is readily hydrolyzed to glutamic acid and free ammonia, the latter excreted in the urine. See also amino acid, protein.

Chemical structure of glutamine
glutamine (glōōˑ·t
·mēn),n an amino acid synthesized within the body from glutamic acid. Used in preventing immunosuppression after exercise and as an aid in recovery after a critical illness. Precaution urged for those sensitive to monosodium glutamate, those who suffer from manic conditions, and patients who are taking anticonvulsants. Also called
L-glutamine.
L-glutamine.

Glutamine.
glutamine
Gln; an amide of glutamic acid, an amino acid occurring in proteins; it is an important carrier of ammonia to the kidney where it is released by glutaminase.
glutamine synthetase
enzyme catalyzing the synthesis of the amino acid, glutamine from glutamate ammonia and ATP. Major means of detoxifying ammonia from amino acid catabolism in peripheral tissues and then transporting the ammonia as the amido-N in glutamine to the liver of kidney.
