Abstract
Summary
The effect of pH on glucose transport was studied in 131 everted gut sacs of upper small bowel from 25 hamsters, using phosphate buffered solutions over the pH range 4.80-7.82. The relationship between pH and glucose transport rate revealed a bell-shaped curve with a pH optimum of 5.9. Under these conditions, in which intraluminal pH adjustment by the small bowel was eliminated, a pronounced effect of pH on glucose absorption was demonstrated.
