Chemical synthesis is playing an increasingly important role in peptide production. Peptide drug chemical synthesis is usually carried out by coupling the carboxyl group of the incoming amino acid to the N-terminus of the growing peptide chain. Due to the complex nature of in vitro protein synthesis, amino acids are added to the growing peptide chain in a precise, gradual and cyclic manner. chemically synthesized polypeptide https://www.pepdd.com/services/peptide-drug-chemical-synthesis.html
