So the glute three are these molecules that also generate the basal uptake rate, but we also find them predominantly in the nerve cells found inside our brain, in the neurons. We find them in the membrane of the dendrites, as well as the axons of the nerve cells of the brain. Now, why is it important that we have a high concentration of these glute three in the brain? Well, because the brain cells depend on glucose molecules. And the brain cells are arguably some of the most important cells in our body. And they need to get that glucose first before any other cell actually gets the glucose.
