How Is a Dipeptide Broken Down?

How are dipeptides and polypeptides broken down? Proteases catalyse the hydrolysis reaction, turning peptides into their amino acids. A water molecule is used to break the peptide bond, reforming the amine and carboxylic acid groups.

How a dipeptide is formed and broken down?

A dipeptide is formed when two Amino acids join together by one Peptide bond. This happens via a Condensation Reaction. The bond between the two amino acids forms between the carboxyl group on one and the amino group on another, therefore producing a water molecule as a product.

Where are dipeptides broken down?

Dipeptidases are secreted onto the brush border of the villi in the small intestine, where they cleave dipeptides into their two component amino acids prior to absorption.
