Suggest a reason why amino acids are usually more soluble at pH extremes than they are at neural pH.

Two different proteins X and Y are dissolved in aqueous solution at 37 ∘C. The proteins bind in a 1:1 ratio to form XY. A solution that is initially 1.00 mM in each protein is allowed to reach equilibrium. At equilibrium, 0.17 mM of free X and 0.17 mM of free Y remain.  What is Kc for the reaction? Express your answer using two significant figures.
