CAS 484-42-4: Angiotensin I
Description:Angiotensin I is a peptide hormone that plays a crucial role in the regulation of blood pressure and fluid balance in the body. It is a decapeptide, consisting of ten amino acids, and is derived from angiotensinogen, a precursor protein produced by the liver. Angiotensin I is biologically inactive but is converted into the active form, angiotensin II, by the action of the enzyme angiotensin-converting enzyme (ACE). This conversion is a key step in the renin-angiotensin system, which regulates blood pressure and electrolyte balance. Angiotensin I is characterized by its specific amino acid sequence, which includes proline and histidine residues, contributing to its structural properties. It is soluble in water and has a relatively short half-life in circulation, making it a transient component of the renin-angiotensin system. The study of angiotensin I and its derivatives is significant in pharmacology, particularly in the development of antihypertensive medications that target the renin-angiotensin system to manage conditions such as hypertension and heart failure.
