Glutamine is the most abundant amino acid in our body. You need to train hard, but intense exercise can deplete our bodies of up to 50% of its glutamine.

role of SNAT6 with speciﬁc insights into the glutamate–glutamine cycle. We used tritium-labeled amino acids in order to demonstrate that SNAT6 is functioning as a glutamine and glutamate transporter. SNAT6 revealed seven predicted transmembrane segments in a homology model and was localized to caveolin rich sites at the plasma membrane. Figure 2.

Glutamate glutamine cycle

By this mechanism the steep gradient between high intracellular glutamate concentration (up to 12 mmol/L) in neurons and low glutamate concentration in the synaptic cleft (1-3 µmol/L) can be maintained. A metabolite shuttle known as the glutamate/GABA-glutamine cycle describes the release of neurotransmitter glutamate or GABA from neurons and subsequent uptake into astrocytes. In return, astrocytes release glutamine to be taken up into neurons for use as neurotransmitter precursor. The gold standard for studies of glutamate–glutamine (GABA) cycling and its connections to brain biosynthesis from glucose of glutamate and GABA and their subsequent metabolism are the elegant in vivo studies by 13 C magnetic resonance spectroscopy (NMR), showing the large fluxes in the cycle. However, simpler experiments in intact brain tissue (e.g., immunohistochemistry), brain slices, cultured brain cells, and mitochondria have also made important contributions to the understanding of In the CNS, glutamate is synthesised in neurons as part of the glutamate–glutamine cycle. 5,6 1.

The glutamate-glutamine shuttle ( SI Appendix , Fig. S4 ) between neurons and glia contributes 50–60% of a glutamate neurotransmitter ( 12 , 13 , 23 ) with intracellular sources such as glycolysis supplying the remainder. A metabolite shuttle known as the glutamate/GABA‐glutamine cycle describes the release of neurotransmitter glutamate or GABA from neurons and subsequent uptake into astrocytes.
