Chapter 21, Problem 21.49P

Interpretation Introduction

(a)

Interpretation:

The structure of leucylvalyltryptophan should be drawn, amide bonds should be labelled, N-terminal and C-terminal amino acids should be identified along with the name of peptide by suing three-letter symbols of amino acids.

Concept Introduction:

Proteins are polymeric biomolecules which are formed by the polymerization of amino acids. Amino acids are the organic molecules with $–{\text{NH}}_{\text{2}}$ and −COOH functional groups bonded on the same carbon atom of the molecule.

They polymerise by peptide linkage to form dipeptide, oligopeptide and polypeptide molecules. Each peptide bond formation is a condensation reaction that occurs with the elimination of water molecule.

Interpretation Introduction

(b)

Interpretation:

The structure of phenylalanylserylthreonine should be drawn, amide bonds should be labeled, N-terminal and C-terminal amino acids should be identified along with the name of the peptide by suing three-letter symbols of amino acids.
