Abstract

Previously unidentified constituents in fatty acid extracts of strains and species of Yersinia (Tornabene, T.G. (1973) Biochim Biophys Acta, 306, 173-185) have been identified as methanolyzed cyclopropane fatty acid methyl esters. These derivatized open ring acids were artifacts formed by a standard mild acidic-methanolysis procedure. The quantities of artifacts produced in natural mixed lipids were highly significant in comparison to the trace amounts obtained from pure samples of cyclopropane fatty acids. Characterization of the methanolyzed derivatives established the location of the propane ring in the cyclopropane fatty acids as 9,10-methylene hexadecanoic and 11, 12-methylene octadecanoic acids.
