in order to investigate the source of free amino acids found in the gut lumen during absorption of dipeptides , as well as evaluating the role of brush border peptidases in the mucosal hydrolysis of dipeptides during absorption , rates of dipeptide disappearance and appearance of hydrolytic products were measured during perfusion of rat jejunum and ileum in vivo with buffered and unbuffered 10 mm solutions of glycl-l-phenylalanine ( gly-phe ) and l-phenylalanyl-glycine ( phe-gly ) .
