glu·ta·mine (Gln, Q),(glū'tă-mēn, -tă-min, glū-tam'in),
The δ-amide of glutamic acid, derived by oxidation from proline in the liver or by the combination of glutamic acid with ammonia; the l-isomer is present in proteins, blood, and other tissues, and is an important source of urinary ammonia, being broken down in the kidney by the action of the enzyme glutaminase; nonenzymatically, it is converted to 5-oxoproline.
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.
A nonessential amino acid, C5H10N2O3, occurring widely in plant and animal tissue and proteins and produced commercially for use in medicine and biochemical research.
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.
The δ-amide of glutamic acid, derived by oxidation from proline in the liver or by the combination of glutamic acid with ammonia; the l-isomer is present in proteins and in blood and other tissues, and is an important source of urinary ammonia.
glutamine (Q, Gln)one of 20 AMINO ACIDS common in proteins that has a polar ‘R’ structure and is soluble in water.
glutaminethe amide of amino acid glutamate, synthesized in skeletal muscle. Glutamine is one of the major fuels of the gut lining, and of the cells of the immune system. It is also a precursor for the gluconeogenesis that occurs in the kidneys after an overnight fast or in starvation. Glutamine supplementation is popular among athletes attempting to maintain a healthy immune system during training. See also glucogenic amino acids, ergogenic aids; appendix 4.4 .
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
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.
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.
