Abstract
IT is well established that there are specific processes for the active transfer of both sugars and amino-acids by the small intestine. Since these substances can be transferred against a concentration gradient and since this transfer is prevented by metabolic inhibitors, energy derived from metabolism is presumably utilized in the transfer mechanisms. It would seem, therefore, that the mechanisms for sugar and amino-acid transfers might share some step in the overall absorption process even if it was only the linkage with a common energy source. Experiments were carried out to investigate this possibility.
