Abstract
IN their study of the effect of amino-acids on the intestinal absorption of sugars in normal hamsters, Hindmarsh, Kilby and Wiseman1 observed that although L-glucose was not transported against its concentration gradient, its absorption down its concentration gradient was markedly reduced by L-histidine. They concluded that L-glucose probably participated in an active transport system. In order to investigate this problem further, we have carried out experiments using sacs2,3 of everted mid-small intestine from rats kept on a restricted diet (6–10 g food/day for 9 days); on such a diet this species shows enhanced active absorption of D-glucose and L-histidine4,5.
