The aim of the study was to determine if differences in the molecular size of two protein sources affect in vivo intestinal absorption rates of amino acids under normal feeding conditions. Accordingly, the portal absorption rate of amino acids was studied in rats fed semi-synthetic diets containing native casein (NC) or enzymatically hydrolysed casein as the only protein sources. Enzymatic casein hydrolysate (ECH) consisted of a mixture of free amino acids (51.2% with respect to total amino… Expand
