Blood-brain barrier is a protective barrier formed by the endothelial cells of the brain capillary walls to prevent viruses, bacteria and other harmful chemicals from infecting the brain and so prevents brain damage. Small, uncharged molecules like and fat-soluble molecules can easily cross the blood-brain barrier, while large molecules like glucose , amino acids , harmful chemicals, chemotherapy drugs, etc., cannot cross the barrier. Active transport is an energy-mediated pumping mechanism that pumps chemicals like glucose, amino acids, purines, choline, few vitamins and iron.
