Question
Chapter 24, Problem 24.37SP
Interpretation Introduction
Interpretation: A structure for the unknown pentapeptide is to be proposed.
Concept introduction: Pentapeptide is the peptide consisting of five amino acids. Peptide synthesis requires the formation of amide bonds between proper amino acids in proper sequence. A peptide is treated with phenyl isothiocyanate followed by acid hydrolysis.
To determine: A structure for the unknown pentapeptide.
