Question

Change of pH may disturb protein structure and thus affecting its functions. Which level of protein structure is not generally affected by the change in pH ? (A) Primary structure (B) Quaternary structure (C) Secondary structure (D) Tertiary structure

The primary structure of protein has peptide bonds only that are resistant to the change in pH . In contrast, secondary and tertiary structure of proteins have covalent bonds, hydrogen bonds that can be easily affected by the change in pH • The primary structure of a protein — its amino acid sequence — drives the folding and intramolecular bonding of the linear amino acid chain, which ultimately determines the protein's unique three-dimensional shape.
