Concept explainers
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
