Peptides from australian frogs. Structures of the caeridins from Litoria caerulea

The secretions of the parotoid glands of the Australian tree frog Litoria caerulea contain twenty-five peptides of which six, the caeridins, have molecular weights in the 1100–1550 dalton range. The paper describes the primary structures of the caeridins, and indicates how the exudate's caeridin composition varies with the geographic location of the species.
