Fmoc-L-Lys(C20-OtBu-L-Glu(OtBu)-AA-AA)-OH

The “Fmoc” group is a protecting group used in solid-phase peptide synthesis to manage the reaction, while the lengthy “C20-OtBu-L-Glu(OtBu)-AA-AA” side chain is essential for creating the final, complex peptide structure. Fmoc-L-Lys(C20-OtBu-L-Glu(OtBu)-AA-AA)-OH is a specialized chemical intermediate employed to synthesize therapeutic peptides, most notably Tirzepatide, a dual GIP and GLP-1 receptor agonist for type 2 diabetes and weight loss.
