Tryptophan is an amino acid that contains an amino group (-NH2) and a carboxylic acid group (-COOH). In its zwitterionic form, which is the predominant form at physiological pH, the amino group gains a positive charge by accepting a proton (H+), while the carboxylic acid group loses a proton, resulting in a negative charge.

Therefore, option 3 correctly identifies the functional groups present in the zwitterionic form of tryptophan as the carboxylic and amino groups. These functional groups play crucial roles in the structure and function of tryptophan in biological systems.
