Question

Name the tripeptides involved in the absorption of amino acids.

Answer 1

Hey there!!!!



=>> The tripeptide(Gly-Ala-Leu) on hydrolysis gives three α-amino acids.



Hope it helped!!!!!!☺️

Answer 2

These small peptides are absorbed into the small intestinal epithelial cell by cotransport with H+ ions via a transporter called PepT1. Once inside the enterocyte, the vast bulk of absorbed di- and tripeptides are digested into amino acids by cytoplasmic peptidases and exported from the cell into blood.
