General Description
Angiotensin II is a peptide formed from angiotensin 1 under the action of angiotensin-converting enzyme. The main function is to constrict blood vessels, causing blood pressure to rise. Therefore, if Angiotensin II is elevated, blood pressure may increase, which may also increase the excitability of the sympathetic nervous system, leading to increased heart rate, increased myocardial contractility, and increased cardiac ejection. Therefore, if Angiotensin II is elevated, blood pressure will also rise significantly.
The Mechanism of Action of Angiotensin II:
Angiotensin II is the most important component of angiotensin. There are angiotensin receptors on the human body's blood vessel smoothing machines, adrenocortical zona glomerulosa cells, and on cells in some parts of the brain, heart, and kidneys.
Angiotensin II binds to angiotensin receptors, causing corresponding physiological effects. Angiotensin acts on vascular smooth muscle, constricting arterioles throughout the body and increasing arterial blood pressure. Angiotensin II is one of the most powerful vasoconstrictor substances known.
What you should know about "Angiotensin II"
Angiotensin II (AngII) is the main response factor of RAS. Its molecular weight is 104612 and it is an octapeptide.
There are three ways to generate angiotensin II. The first is the ACE pathway, which removes the two terminal amino acids from Ang I under the catalysis of ACE and turns it into angiotensin II. This is the main source of Ang II. The second is the gastric pathway. In the chymase pathway, in vascular tissue, ACE is mainly located in endothelial cells, while chymase is mainly located in the outer membrane. 70% of Ang II in human vascular tissue is catalyzed by chymase, and 30% is catalyzed by ACE. This indicates that vascular Tissue angiotensin II is produced primarily by the chymase pathway. The third is the non-ACE non-chymase pathway, which is mainly produced by angiotensin catalyzed by serine proteases such as cathepsin G, trypsin, and kallikrein.
Angiotensin II is not only the strongest vasoconstrictor in the body, but also a growth factor that promotes growth. It can cause cardiac hypertrophy, increase intracellular DNA and RNA content and metabolic transformation, and also increase protein synthesis.
