Glucose serves as a main energy source for the majority of human cells. It is ingested with food, absorbed in the digestive tract and transported via blood to supply the whole body. Facilitated passive intracellular glucose transport is mediated by GLUT (glucose transporters) proteins while SGLT (sodiumglucose transport) proteins participate in its active transport. GLUT and SGLT expression is tissuedependent and influenced by its role in carbohydrates metabolism.
