Answer:
Changes in pH change the attractions between the groups in the side chains of the protein.
Explanation:
The interactions between the side chains of the amino acids determine the shape of a protein.
In each case the ionic attraction disappears, and the protein shape unfolds.
Hydrogen Bonding
Various amino acid side chains can hydrogen bond to each other. Examples are:
• Two alcohols: Ser, Thr, and Tyr.
• Alcohol and amine: Ser and Lys
• Alcohol and amide: Ser and Asn
• Alcohol and acid: Asp and Tyr
• Two acids: Asp and Glu
Changing the pH disrupts the hydrogen bonds, and this changes the shape of the protein
