GGGCYFQNCPKG-NH2 (disulfide Cys4–Cys9)
GGGCYFQNCPKG
Length counts residues; formula and mass are the stored free-base values from cited sources; CAS and PubChem identify the substance in public registries. More detail: length & peptide bonds, molecular weight
Structure & modifications
Cyclic vasopressin core plus a tri-glycine N-terminal extension.
Notes
Terlipressin is triglycyl-lysine-vasopressin: a circulating, prodrug-like extension that releases lysine vasopressin after sequential N-terminal glycine cleavage.
| Feature | Detail |
|---|---|
| Length | 12 (Gly-Gly-Gly + vasopressin core) |
| Disulfide | Cys4–Cys9 (this numbering) |
| C-terminus | Gly-NH2 |
| CAS / PubChem | 14636-12-5 / 72081 |
Compare with AVP and desmopressin: residue 8 chemistry and the triglycine extension make terlipressin a distinct registry identity.
