4. Refer to the data below to answer the following questions:
The octapeptide saralasin is a specific antagonist of angiotensin II. A derivative of saralasin is used
therapeutically as an antihypertensive. Amino acid analysis of saralasin show the presence of the
following amino acids:
Ala, Arg, His, Pro, Sar, Tyr, Val, Val
A.Sar is the abbreviation for sarcosine, N-methyl aminoethanoic acid. Draw the structure of sarcosine.
B. N-Terminal analysis by the Edman method shows saralasin contains sarcosine at the N-terminus.
Partial hydrolysis of saralasin with dilute hydrochloric acid yields the following fragments:
Tyr-Val-His
Sar-Arg-Val
His-Pro-Ala
Val-Tyr-Val
Arg-Val-Tyr
What is the structure of saralasin?
