Glucose from blood enters the brain by a transport protein. Glucose is the primary energy substrate of the brain. Glucose transport protein (GLUT-1) is highly enriched in brain capillary endothelial cells.These transporters carry glucose molecules through the blood brain barrier.lucose is the primary energy substrate of the brain.
