Define the following terms in relation to proteins:
i) peptide linkage
ii) denaturation
i) peptide linkage
ii) denaturation
Solution
(i) \textbf{Peptide linkage} — the amide bond (–CO–NH–) uniting the carboxyl of one amino acid with the amino group of the next.
(ii) \textbf{Denaturation} — the collapse of a protein's secondary/tertiary structure (uncoiling, unfolding, loss of activity) on heating or pH change; the primary sequence remains (coagulated egg white).
(ii) \textbf{Denaturation} — the collapse of a protein's secondary/tertiary structure (uncoiling, unfolding, loss of activity) on heating or pH change; the primary sequence remains (coagulated egg white).
