What is Which among the following is the shoest peptide? and explain in detail?
Angiotensinogen is a 452-amino-acid-long protein, which is produced by the liver. Angiotensin I, comprising the first 10 amino acids of angiotensinogen, is produced by cleavage of a leucine-valine bond by renin. The 10-amino-acid angiotensin I is completely inactive but is subsequently conveed to the eight-amino-acid peptide hormone, angiotensin II. This reaction is catalyzed by angiotensin-conveing enzyme (ACE). Angiotensin II can also be conveed to a seven-amino-acid angiotensin III. Vasopressin or AVP is a nonapeptide. Ref: Lorenzo A.J.
