The origin of each of the signal shown for dipotassium salt of
Concept Introduction:
The carbon atom attached to the single bonded oxygen atom is the anomeric carbon atom. The anomeric carbon atom is attached to one proton and one phosphate group. The splitting of a signal depends on the number of vicinal protons for the anomeric proton. Phosphorus atom also splits the vicinal protons since the nuclear spin for phosphorus atom is

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?
