the rat everted gut sac was used as a model of intestinal protein and peptide handling to study small intestinal binding and uptake of different gliadin peptide fractions ( b1 , b2 , b3 , b4 ) in comparison with bovine serum albumin ( bsa ) , alpha-lactalbumin ( alpha-la ) , and a bsa peptide fraction ( bsa-p ) .
