Like any other amino acid, tryptophan possesses both acidic and basic characteristics, referred to as amphoteric substances.

It acts as an acid at pH below 5.89 and as a base at pH above 5.89.

5.89 here is the isoelectric point of tryptophan, a pH value where its overall charge is zero and wherein it neither acts as an acid, nor as a base.
