Is alanine ionizable

WebAnswer (a) The pI of alanine is well above the pKa of the a-carboxyl group and well below the pKa of the a-amino group. Hence, at pH u0005 pI, both groups are present predominantly in their charged (ionized) forms. (b) … Web14 apr. 2024 · Hence, pKa can be defined as the pH at which the concentrations of the protonated and unprotonated forms of a particular ionizable species are equal. The pKa also equals the pH at which the ionizable group is at its best buffering capacity; that is the pH at which the solution resists changes in pH most effectively.
