Glutamine: recent developments in research on the clinical significance of glutamine
Current Opinion in Clinical Nutrition and Metabolic Care, 2004The aim of this review is to describe the clinical relevance of supplementation of glutamine from the recent literature. First, new basic research is examined and subsequently recent clinical trials and a metaanalysis are illustrated.Glutamine has a major impact on the functionality of the immune system.

The metabolism of glutamine in the bovine lens: Glutamine as a source of glutamate
Experimental Eye Research, 1973Abstract The metabolism by the intact bovine lens of l -[ U - 14 C]glutamine has been studied and compared with that of l -[ U - 14 C]glutamate. [ 14 C]Glutamine was taken up and oxidized to 14 CO 2 at three times the rate of [ 14 C]glutamate. [ 14 C]Glutamine was largely converted to [ 14 C]glutamate, which was found in the lens in the free form,

Neuronal Glutamine Utilization: Glutamine/Glutamate Homeostasis in Synaptosomes
Journal of Neurochemistry, 1990Abstract: The synaptosomal metabolism of glutamine was studied under in vitro conditions that simulate depolarization in vivo. With [2‐15N]glutamine as precursor, the [glutamine]i was diminished in the presence of veratridine or 50 mMKCl, but the total amounts of [15N]glutamate and [15N]aspartate formed were either equal to those of control ...

Dietary glutamine suppresses endogenous glutamine turnover in the rat
Metabolism, 2000Plasma glutamine turnover was determined using 1-14C-labeled glutamine in rats that consumed crystalline amino acid diets containing the equivalent of 16% protein with 25% of the amino acids as glutamine or a control diet containing no glutamine (or glutamate) for 10 days.

Conversion of glutamic acid to glutamine by retinal glutamine synthetase
Experimental Eye Research, 1973Abstract There is a qualitative correlation within a given retinal tissue between level of glutamine synthetase, as measured by its transferase activity, and ability of the tissue to convert glutamic acid to glutamine in vitro. The present study shows this to be the case for age-dependent endogenous enzyme activity, cortisol-induced enzyme activity ...

Adenosinetriphosphate in Glutamine Synthesis
Nature, 1948IT was shown by Krebs1 that the energy required for the synthesis of glutamine from glutamic acid and ammonia which occurs in tissue slices of brain cortex, can be furnished by the oxidation of glucose. In the course of a more general investigation of phosphate-transferring enzymes, evidence has been obtained that adenosinetriphosphate is the immediate

The Glutamine Transporters and Their Role in the Glutamate/GABA–Glutamine Cycle
2016Glutamine is a key amino acid in the CNS, playing an important role in the glutamate/GABA-glutamine cycle (GGC). In the GGC, glutamine is transferred from astrocytes to neurons, where it will replenish the inhibitory and excitatory neurotransmitter pools.
