[Sar1] Angiotensin II features a sarcosine substitution at residue 1, altering backbone flexibility and metabolic susceptibility. The modification preserves the core heptapeptide region essential for receptor attachment. Its altered N-terminal geometry allows refined analysis of angiotensin-binding interactions. Researchers apply it in probing structural determinants of peptide-regulated signaling.
