The hydrolysis of a dipeptide results in the breaking of the peptide bond between the two amino acids that make up the dipeptide. This reaction is catalyzed by enzymes called peptidases or proteases. The products of hydrolysis are two individual amino acids.

The general reaction for the hydrolysis of a dipeptide can be represented as follows:

H2O + R1-CO-NH-R2 → R1-COOH + R2-NH2

where R1 and R2 represent the side chains of the two amino acids.

The hydrolysis of dipeptides is an important step in the digestion of proteins. In the human digestive system, dipeptides are broken down into individual amino acids by enzymes such as dipeptidases and aminopeptidases. These amino acids can then be absorbed into the bloodstream and used for various metabolic processes.
