(a)

Interpretation Introduction

Interpretation: For the tripeptide, Ala−Val−Gly, the amino acid residue which is hydrophilic has to be stated.

Concept introduction: The amino acid that has one amine group, one carboxyl group and a polar side chain is called polar amino acid. The polar amino acid is soluble in water. Thus, it is hydrophilic in nature.

(b)

Interpretation Introduction

Interpretation: For the tripeptide, Ala−Val−Gly, the amino acid residue which is hydrophobic has to be stated.
