The method based on high-performance liquid chromatography currently used to determine the lipid levels of octadeca-9(Z),11(E)-dienoic acid in human serum fails to distinguish between this acid and octadeca-10(E),12(Z)-dienoic acid. Adducts with the fluorescent dienophile 4-[3-(1-propenyl)propyl]-1,2,4-triazoline-3,5-dione permit the separation of these two isomeric acids as does gas-liquid chromatography of their methyl esters, but these alternatives produce equivocal results when applied to biological samples.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
