Tirzepatide in research
Tirzepatide is a 39-residue chain whose backbone derives from glucose-dependent insulinotropic polypeptide, engineered so that it binds both the GIP receptor and the receptor for glucagon-like peptide-1. Three structural features define it. Alpha-aminoisobutyric acid is substituted at two positions, obstructing the dipeptidyl-peptidase cleavage a natural incretin sequence presents; a C20 diacid is tethered to a lysine side chain by a spacer made from glutamate and two ethylene-glycol units; and the C-terminus is amidated. CAS 2023788-19-2, formula C225H348N48O68, 4813.5 g/mol. Sequences of this length carrying this many non-standard elements are demanding to synthesise, and confirmation against the expected mass is the check that a vial holds the intended molecule rather than a close relative of it.

Frequently asked questions
What backbone is tirzepatide built on?
A GIP-like sequence rather than a GLP-1 one. Despite being described as a dual agonist, the chain is closer in origin to glucose-dependent insulinotropic polypeptide, with the modifications that give it activity at the GLP-1 receptor engineered on top. That lineage is a structural fact about the molecule and is how the receptor-pharmacology literature describes it.
What sits between the peptide and the diacid?
A short spacer built from a glutamate residue and two ethylene-glycol-derived units, joining a lysine side chain on the peptide to the C20 diacid. The spacer is part of the defined structure and contributes to the expected mass that identity work is read against.
Which receptors define its class?
GIP and GLP-1 — the receptor-pharmacology literature describes it as a dual agonist at those two. That is a classification of the molecule, used in binding and signalling assays. It is not a statement about any application, and Index Peptides supplies the peptide for laboratory research only.
