Amino acids are the best-known examples of zwitterions. These compounds contain an ammonium and a carboxylate group and can be viewed as arising a kind of intramolecular acid-basereaction: The amine group deprotonates the carboxylic acid.Ref: Textbook of Medical Biochemistry, MN Chatterji, 8th Edition, Page no: 81', 'role': 'assistant'}]
