Peptide vs. Dipeptide: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on December 11, 2023
Peptides are chains of amino acids; dipeptides are the simplest peptides, consisting of just two amino acids linked together.

Key Differences

Peptides are chains of amino acids connected by peptide bonds. They are essential for various biological functions. Dipeptides, on the other hand, are the simplest form of peptides, consisting specifically of two amino acids linked by a single peptide bond.
