Alanine is an amino acid with the following structure. H3C re NH2 You have an aqueous solution of alanine at a concentration of 0.5 mol/L. You then add sodium hydroxide (NaOH) to the solution until its pH is equal to 7.4. The equilibrium constants for the deprotonation steps of alanine are: Kal Alal: H:01 pK4,1 = 2.31 Ala Ala 1-HOT) K..2 pk. 2 = 9.69 Ala D Question 15 5 pts Is the following statement correct? "Neutral alanine" is actually a so-called zwitter ionic molecule, with one negative charge from the deprotonated carboxylic group, and one positive charge from the protonated amino group. O True False
