Temporin

Temporins are a family of peptides isolated originally from the skin secretion of the European red frog, Rana temporaria. Peptides belonging to the temporin family have been isolated also from closely related North American frogs.

In elephants, temporin is secreted by temporal glands during the period of musth. It contains proteins, lipids (notably cholesterol), phenols, cresols and sesquiterpenes (notably farnesol and its derivatives).
