Abstract

Three isomeric C19 monoolefins with the carbon skeleton of pristane (2,6,10,14-tetramethylpentadecane) have been isolated from mixed zooplankton of the Gulf of Maine and from liver oils of various marine fishes and mammals. The structures have been elucidated. Zamene (norphytene), the terminal olefin, is a minor component of the mixture. The usage of the older trivial name "zamene" should be restricted to the total mixture of marine C19 monoolefins with the pristane skeleton. Conventional chemical nomenclature should be used for individual isomers.
