THE ABSORPTION OF PROTEIN SPLIT PRODUCTS FROM CHRONIC ISOLATED COLON LOOPS

Abstract
Isolated large bowel loops were prepared in dogs and the absorption of hydrolyzed peptone and of amino acid solns. studied. A comparison was made with absorption of similar solns. from a small bowel loop. Amino acids were readily absorbed from chronic isolated loops of the large bowel. Some of the higher split products of protein digestion were apparently absorbed from such loops. Increasing concns. of total N and amino N in the large bowel loop resulted in increasing amts. absorbed in a given time. The rate of absorption of both types of substances was slower from the large than from the small bowel. The rate of absorption of amino N was more rapid from the protein hydrolysate than from the amino acid mixture.
