Protecting group chemistry is essential to temporarily mask these reactive sites, ensuring that the coupling occurs only at the intended positionsProtein Ligases: Nature's Gift for Protein/Peptide Synthesis.

* Coupling Reagents: Efficient coupling of amino acids requires specialized reagents that activate the carboxyl group of the incoming amino acid, facilitating its reaction with the free amino group on the growing peptide chain.

* Purification and Characterization: After synthesis, crude peptides must be purified to remove unreacted starting materials, deletion sequences, and other impurities. Techniques like high-performance liquid chromatography (HPLC) are commonly used.
