Concept explainers
a.
To draw:
The structural formula for the given peptide Phe-Glu.
Introduction:
The condensation reaction between the N-terminal of one amino acid and carboxylic group of another amino acid leads to the formation of a peptide bond. According to the convention, N-terminal of amino acid in a peptide bond is written on the left hand side while the C-terminal of amino acids is written on the right hand side.
b.
To draw:
The structural formula for the given peptide KCG.
Introduction:
The condensation reaction between the N-terminal of one amino acid and carboxylic group of another amino acid leads to the formation of a peptide bond. According to the convention, N-terminal of amino acid in a peptide bond is written on the left hand side while the C-terminal of amino acids is written on the right hand side.
c.
To draw:
The structural formula for the given peptide His-Met-Gln.
Introduction:
The condensation reaction between the N-terminal of one amino acid and carboxylic group of another amino acid leads to the formation of a peptide bond. According to the convention, N-terminal of amino acid in a peptide bond is written on the left hand side while the C-terminal of amino acids is written on the right hand side.
d.
To draw:
The structural formula for the given peptide WY.
Introduction:
The condensation reaction between the N-terminal of one amino acid and carboxylic group of another amino acid leads to the formation of a peptide bond. According to the convention, N-terminal of amino acid in a peptide bond is written on the left hand side while the C-terminal of amino acids is written on the right hand side.
