[Answered] There's a protein with a neutral amino acid (A) beside a positively-charged amino acid (B). At neutral pH, A is able to remain next to B without any issue. But when the pH changes to 5, suddenly, A moves far away from B. Why? 1) A was likely in a protonated form at neutral pH and became positively charged with the pH change, thus repelling from B. 2) A was likely in a deprotonated form and became negatively charged with the pH change, thus repelling from B. 3) A was likely in a protonated form and became negatively charged with the pH change, thus repelling from B. 4) A was likely in a deprotonated form at neutral pH and became positively charged with the pH change, thus repelling from B.
