(Sar¹)-Angiotensin II（Cat No.:I044234）is a synthetic analog of the natural peptide hormone angiotensin II, in which the first amino acid, aspartic acid, is replaced with sarcosine (Sar). This modification enhances the peptide’s resistance to enzymatic degradation and alters its receptor binding properties. (Sar¹)-Angiotensin II retains high affinity for the angiotensin II type 1 receptor (AT₁R), making it a valuable tool in cardiovascular research. It is commonly used to study blood pressure regulation, vasoconstriction, and renal function, and helps elucidate angiotensin II’s role in hypertension and related pathophysiological conditions.
