Define the effect of SCFA on Sodium Absorption?

SCFAs (short chain fatty acids) have a stimulatory effect on sodium absorption from colonic lumen. The unionized SCFA crosses the epithelial cell where it disassociates. The hydrogen ion is then moved back into the lumen in exchange for sodium. Thus, SCFAs provide a powerful stimulant to sodium and water absorption.
