At a pH equal to the isoelectric point (pl) of alanine, the net charge of alanine is zero. Two structures can be drawn that have a net charge of zero, but the predominant form of alanine at its pl is zwitterionic. CH3 H,N CH3 ** H¸N-C H Zwitterionic H Uncharged OH Select statements that explain why alanine is predominantly zwitterionic at its pl. pk of alanine's amino group is more than its pl. pk of alanine's carboxyl group is more than its pl. PK of alanine's carboxyl group is less than its pl. pk of alanine's amino group is less than its pl.
