Blood Glucose (Blood Sugar): How It

WebYour body relies on molecules called glucose transporters (GLUT is the scientific term) to deliver the sugar to cells. GLUT molecules tend to specialize: GLUT2, for example, delivers glucose to the digestive tract, liver, and pancreas; GLUT3 keeps the central nervous system and the brain running; GLUT4 serves the heart, muscles and fat cells.
