Concept explainers
Interpretation :
The similarly between a peptide bond and an ester formed from an acid and alcohol must be explained.
Concept Introduction :
Both esterification and peptide bond formation are condensation reaction in which water is eliminated.

Answer to Problem 6E
In peptide bond formation, an amide is produced from acid and
Explanation of Solution
The peptide bond formation and esterification reaction is represented as follows:
The peptide bond (amide) and ester bond are shown in red.
In both cases, the reaction is condensation as water is removed.
In the peptide bond formation, -CONH bond is formed and in the esterification reaction −COO bond is formed.
Forming a peptide bond is similar to forming an ester from acid and alcohol.

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?arrow_forward
