Tirzepatide is a synthetic peptide of roughly 39 amino-acid residues (molecular formula C225H348N48O68) engineered for dual receptor binding and an extended activity profile.
Structural features
Its sequence blends motifs relevant to both GIP and GLP-1 receptors, and it carries a fatty-acid side chain (acylation) attached through a linker. That lipid modification is a common peptide-engineering strategy to slow clearance and extend half-life in research models — the same idea seen in semaglutide's structure.
How it is made
Peptides like this are typically produced by solid-phase peptide synthesis, building the chain one residue at a time, followed by side-chain conjugation, cleavage, and chromatographic purification. Purity and identity are then confirmed by HPLC and mass spectrometry.
