Angiotensin 1 Human is primarily used in research and diagnostic applications to study the renin-angiotensin system (RAS), which plays a critical role in regulating blood pressure and fluid balance. It serves as a precursor to Angiotensin II, a potent vasoconstrictor, through the action of angiotensin-converting enzyme (ACE). Researchers utilize this peptide to investigate pathways involved in hypertension, cardiovascular diseases, and kidney function. Additionally, it is employed in the development and testing of pharmaceuticals targeting RAS, such as ACE inhibitors and angiotensin receptor blockers, which are commonly used to treat high blood pressure and heart failure. Its application extends to biochemical assays and studies exploring the physiological and pathological roles of angiotensin peptides.
