Concept explainers
(a)
Interpretation : Need to identify the type of interaction found in the tertiary structure of given amino acids.
Concept Introduction : Amino acids are bonded together through peptide bond and form the primary structure of proteins. These peptide chains form alpha and beta secondary structures in which the peptide chains are bonded with each other. The tertiary structure exhibits the interaction between hydrocarbon part ( R-group) of amino acids of peptide chains.
