Intestinal Absorption of Sugars and Amino Acids

Abstract

A short account is given of methods currently in use for the study of intestinal absorption and of the various advantages and shortcomings of these methods. Results obtained in recent studies of intestinal absorption of sugars and amino acids are briefly described. It is pointed out that specific mechanisms responsible for the active transport of these substances exist in the intestine and that competition between one amino acid and another, as well as between one sugar and another, for active transport may take place. Effects of metabolic inhibitors, and cationic changes, on intestinal absorption are described.
