Abstract: | Vitamin D stimulates absorption of spd-glucose in chick jejunum and ileum by a specific action on the maximal velocity of Na+-gradient driven spd-glucose transport across the brush-border membrane of intestinal cells. Induction of spd-glucose transport by either vitamin D-3 or 1,25-dihydroxyvitamin D-3 in embryonic intestine can be blocked by inhibitors of RNA and protein synthesis. |
