Absorption of two tripeptides by the human small intestine: a study using a perfusion technique
Silk, D.B.; Perrett, D.; Webb, J.P.; Clark, M.L., 1974: Absorption of two tripeptides by the human small intestine: a study using a perfusion technique. Clinical Science and Molecular Medicine 46(3): 393-402
Four different peptide solutions were perfused into the human small intestine. After 30 min intraluminal samples were taken. Results showed that glycine was absorbed faster from a glycylglycylglycine solution than from an equivalent glycine solution, and both L-alanine and glycine were absorbed faster from L-alanylglyclglycine than from the equivalent amino acid mixture. Free amino acids were aspirated during the tripeptide perfusions.
