生物活性

Angiotensin I/II 1-5 is a peptide that contains the amino acids 1-5, which is converted from Angiotensin I/II. Angiotensin I is formed by the action of renin on angiotensinogen. Angiotensin II is produced from angiotensin I. Angiotensin II has been investigated for the treatment, basic science, and diagnostic of Hypertension, Renin Angiotensin System, and Idiopathic Membranous Nephropathy[1][2][3].

Angiotensin I/II (1-6) (TFA)

生物活性

Angiotensin I/II 1-6 contains the amino acids 1-6 and is converted from Angiotensin I/II peptide. The precursor angiotensinogen is cleaved by renin to form angiotensin I. Angiotensin I ishydrolyzed by angiotensin-converting enzyme (ACE) to form the biologically active angiotensin II. Angiotensin II has been investigated for the treatment, basic science, and diagnostic of Hypertension, Renin Angiotensin System, and Idiopathic Membranous Nephropathy[1][2][3].

体外研究
(In Vitro)

Angiotensin II is a naturally occurring octapeptide hormone component of the renin-angiotensin-aldosterone system (RAAS) and is a potent vasoconstrictor. Angiotensin II has important roles in cardiovascular, neurologic, and renal physiology, including maintenance of blood pressure, thirst sensation, response to the baroreceptor reflex, determination of renal blood flow and glomerular filtration rate, and electrolyte and free water homeostasis[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
