The journey of mersacidin synthesis via SPPS begins with the selection of an appropriate resin and the attachment of the first amino acid. The most common approach for solid-phase peptide synthesis involves Fmoc (9-fluorenylmethoxycarbonyl) chemistry. In this protocol, the N-terminus of amino acids is protected with the base-labile Fmoc group, while side chains are protected with acid-labile groups2023年1月31日—The beauty of Merrifield's strategy is that chemical reagents can be reacted with a reactive moiety on asolidsupport, then removed by a simple .... After each coupling step, the Fmoc group is removed using a mild base (e.gSolid Phase Peptide Synthesis (SPPS) explained., piperidine), exposing the N-terminus for the next amino acid to be added. This cyclical process of deprotection and coupling, repeated for each amino acid in the mersacidin sequence, gradually builds the peptide chain on the solid support.
