Absorption of glucose and fructose. Glucose and fructose are absorbed from the intestinal lumen (on the left) through the enterocyte (luminal and basolateral membrane) into the circulation (on the right), via different pathways involving SGLT1 and GLUT5, respectively. SGLT1 sodium-dependent glucose transporter 1, GLUT5 glucose transporter 5 (fructose transporter), GLUT2 glucose transporter 2
