WebDec 5, 2024 · The peptide NH2-GHKAKGPRKC-CONH2 (B6) was synthesized on a Fmoc-rinkamide MBHA resin (0.661 mmol, 1135 mg) according to the standard Fmoc procedure with a 4-fold excess of amino acids (3.0 mmol).22 Deprotection of the coupled amino acids was performed by using 20% piperidine in DMF. WebPeptides are synthesized chemically either in solution or on a solid phase. The process involves directed and selective formation of an amide bond between an N-protected amino acid and an amino acid bearing a free amino group and protected carboxylic acid. In solid phase synthesis, the carboxyl protecting group is linked to a polymer support.
