Amphoteric properties of proteins

due to the presence of free carboxylic and free amino groups at the end of protein it can react with acids and bases.

In acidic medium protein carries positive charges at amino group and in alkaline medium it carries negative charges at carboxylic group.

amino acids have both acidic and basic centers so when they react with an acid behave just like a Lewis base (accept the hydrogen ion) and when react with a base behave as an acid so amino acids show dual nature ,such compounds are known as amphoteric compounds.

An amino acid contains both a carboxyl group, which is acidic, and an amine group, which is basic, resulting in an amphoteric molecule.

Proteins are described as amphoteric since the amino acids within a protein are amphoteric. This meaning, that it can absorb anions and cations depending upon what the pH solution is.
