Chapter 21, Problem 92E

Interpretation Introduction

Interpretation: The types of interactions that occur in the given amino acids to maintain their tertiary structure are to be stated.

Concept introduction: Amino acids are the building blocks of proteins. They bind together to form large chain molecules of high molecular masses known as proteins. Aliphatic and aromatic amino acids are non-polar in nature and interact mainly by hydrophobic interactions and vanderwaals forces. Amino acids which are acidic and basic in nature interact through charge-charge interactions and ionic bonds as they are charged molecules and those contain functional groups also interact through hydrogen bonding as they are polarized. These interactions are useful to maintain the tertiary structure of proteins.

To determine: The type of interaction that occurs between the side chains of the given amino acids.
