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.
The crowds go down after Labor Day, the bugs are gone, the temperatures are great for hiking, and the trails are as clear of snow as they will be all year....the leaves also start turning somewhere around the 15th of September.... I was there 9/7 - 9/16, 2008 and 9/4 - 9/21, 2009 (I'll also be there 9/4 - 9/26, 2010). My detailed trip reports are attached in the trip report thread pasted at the top of the Forum. I detail the weather every day of those trips..... Highs are generally upper 50's to mid 70's. Lows at night are 30 to 45 degrees.I had snow one day on each of the trips. However, things are starting to close down....the GTTS road is only open (the entire length) until 9/20 (then it is closed from the West side and accessible from the East.
