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.

Seeing the changing autumn leaves is a longstanding Colorado tradition that generally takes place mid-September to mid-October each year, and AAA Colorado, the Colorado Department of Transportation (CDOT), and Colorado Parks and Wildlife want to let people know where to drive and how to drive safely for some of the best views this season.
For the best colors in the upper elevations of Boulder County and into Summit County and Eagle County, the best times should be Sept. 20 to Sept. 30. For areas south of I-70, in Leadville, Buena Vista and Aspen, the peak time for turning leaves will likely be between Sept. 22 and Oct. 3.
