2016-09-07 · The balance of glutamine and glutamate has been identified in an array of brain conditions (i.e. mental illness, tumor, neurodegeneration) as well as in normal brain function. [iv] The precursor relationship between glutamine and glutamate/GABA is often referred to in scientific and research circles as the Gln/Gly(GABA) cycle .

glutamine synthetase assay. The discovery of a new pathway of brain glutamine synthesis will be paradigm changing, and is likely to have profound consequences for our understanding of how glutamate, glutamine and GABA are made in the brain. This project is expected to have broad

Glutamate itself serves as metabolic precursor for the neurotransmitter GABA, via the action of the enzyme glutamate decarboxylase. Glutamate cannot cross the blood-brain barrier, so even if it is obtained through the diet, it also has to be synthesized in the brain. It is synthesized from α-ketoglutarate, which is an intermediate molecule generated during the Krebs Cycle. Glutamic Acid vs. Glutamate Imbalances of the glutamate–glutamine cycle cause distur- bances in sleeping patterns, mood, and behavior, as well as amnesia and confusion, all of which are symptoms of AD. The distribution of ammonia and glutamate metabolising enzymes in brain supports multi-centric mechanism (s) of regulation. The expression of Arg I and Arg II gets inversely regulated and glutamate-glutamine cycle also operates in Heteropneustes fossilis against hyperammonemia in brain. During hyperammonaemic episodes in patients with urea cycle defects a large proportion of de novo synthesised glutamine is trapped in the brain due to excess formation and limited transport of glutamine across the blood-brain barrier.

Glutamate is synthesized in the central nervous system from glutamine as part of the glutamate–glutamine cycle by the enzyme glutaminase. This can occur in the presynaptic neuron or in neighboring glial cells. Glutamate itself serves as metabolic precursor for the neurotransmitter GABA, via the action of the enzyme glutamate decarboxylase.

The glutamate–glutamine cycle in biochemistry, is a sequence of events by which an adequate supply of the neurotransmitter glutamate is maintained in the central nervous system. Neurons are unable to synthesize either the excitatory neurotransmitter glutamate, or the inhibitory GABA from glucose. Discoveries of glutamate and glutamine pools within intercellular compartments led to suggestion… Although astrocyte glutamine synthetase has the ability to remove ammonia, this is not the major function of this enzyme in the brain. It plays a key role in the glutamate-glutamine cycle (which is also called “glutamine-glutamate/GABA cycle” since GABA is produced by decarboxylation of glutamate).
