Question

Which one of the following compounds can exists in Zwitter ionic form? (A) Amino acid (B) Fat (C) Carbohydrate (D) Alcohol

Tardigrade Admin · Accepted Answer

Amino acids contain amino (—NH2) and carboxyl (—COOH) as functional groups. In aqueous solution, the carboxyl group can lose a proton and amino group can accept a proton, giving rise to a dipolar ion known as Zwitter ion. This is neutral but contains both negative and positive charges.
