(a)
Interpretation:
Synthesis of given set of dipeptides must be drawn with the reagents.
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.
To draw : To draw all steps and reagents for the synthesis of dipeptide Trp-Met
(b)
