Schematic diagram 3. The role of fructose and Glut5 in fructose absorption and fructose-stimulated salt absorption in the small intestine.

Schematic diagram 3

Luminal fructose, via Glut5 action, stimulates PAT1 and NHE3, therefore enhancing salt absorption in the jejunum. The stimulatory effect of luminal fructose on salt absorption in jejunum was completely abrogated in Glut5 null mice (ref. 58).
