Concept explainers
(a)
Interpretation: The structure of peptide with peptide bonds, terminal amino acid and carboxyl group needs to be determined.
Ile-Ala-Gly
Concept Introduction: Proteins are
These amino acids involve in condensation process to form peptides and polypeptides, which further form complex protein molecules. Amino acids are the organic molecules with both
(a)
Answer to Problem 9A
Explanation of Solution
In a tripeptide, N-terminus must be written as left side whereas the C-terminus must be right side.
(b)
Interpretation: The structure of peptide with peptide bonds , terminal amino acid and carboxyl group needs to be drawn.
Gly-Ser
Concept Introduction: Proteins are biomolecules, which are composed of certain monomer units such as amino acid. These are carboxylic acids with one amino group bonded on alpha-C atom of the molecule.
These amino acids involve in condensation process to form peptides and polypeptides, which further form complex protein molecules. Amino acids are the organic molecules with both
(b)
Answer to Problem 9A
Explanation of Solution
In a dipeptide Gly-Ser, N-terminus must be written as left side whereas the C-terminus must be right side.
(c)
Interpretation: The structure of peptide with peptide bonds, terminal amino acid and carboxyl group needs to be drawn.
Ser-Gln
Concept Introduction: Proteins are biomolecules, which are composed of certain monomer units such as amino acid. These are carboxylic acids with one amino group bonded on alpha-C atom of the molecule.

Answer to Problem 9A
Explanation of Solution
In a dipeptide Ser-Gln, N-terminus must be written as left side whereas the C-terminus must be right side.
(d)
Interpretation: The structure of peptide with peptide bonds, terminal amino acid and carboxyl group needs to be drawn.
Cys-Asn-Gly
Concept Introduction: Proteins are biomolecules, which are composed of certain monomer units such as amino acid. These are carboxylic acids with one amino group bonded on alpha-C atom of the molecule.
