All amino acids have at least two functional groups with acidic or basic properties. In alanine, the carboxylic acid group has Ka = 4.5 x 10-3 and the amino group has Kb = 7.4 x 10-5.
Three ions of alanine are possible when alanine is dissolved in water.
Which of these ions would predominate in a solution with [H+] = 1.0 M? In a solution with [OH-] = 1.0 M?
