Bradykinin is a linear nonapeptide released by blood plasma globulin in response to a wasp sting. It is a very potent pain-causing agent. Its constituent amino acids are 2R, G, 2F, 3P, S. The sue of 2,4-dinitrofluorobenzene and carboxypeptidase shows that both terminal residues are arginine. Partial hydrolysis of bradykinin gives the following di- and tripeptides: FS + PGF +PP + SPF + FR + RP
