Answer:
The correct answer is - B. the chemical properties of the peptide bonds.
Explanation:
The difference between the structures of catalase from other proteins depends on the chemical properties of the peptide bonds present in between the amino acids which decide the pH and temperature by their disruption. These bonds present between two alpha-amino acids when carboxyl of one amino acid interacts with the amino group of the other to form an amide-type covalent bond.
