Angiotensin I II (1-6) TFA is a chemical compound comprising amino acids 1-6. It is derived from the Angiotensin I II peptide, which is formed by the cleavage of the precursor angiotensinogen by renin. The resulting Angiotensin I is then hydrolyzed by angiotensin-converting enzyme (ACE) to produce biologically active Angiotensin II. Angiotensin II has been extensively studied for its potential applications in the treatment of Hypertension, Renin Angiotensin System, and Idiopathic Membranous Nephropathy[1][2][3].
