The formation of peptide bonds—the chemical bond between amino acids—in protein synthesis is one of the most important biochemical reaction steps. Without the development of structurally and catalytically active polymers, there would be no life on our planet. However, the formation of large, complex oligomer systems is prevented by the high energetic barrier of peptide condensation in aqueous solution.
