Four possible peptides that will be formed when L-phenylalanine and L-alanine is treated with DCC need to be drawn. Concept introduction: Peptides are a chain of amino acids that are linked together by amide bond. The key steps involved in peptide synthesis is, Installation of appropriate protecting groups in amino acid Coupling of protected amino acids using DCC Deprotection of protecting groups to give the final peptide. Please remember that DCC is not a regioselective catalyst. Hence when DCC is used to couple two different amino acids, four different peptides are formed.
