Studies on the metabolism of unsaturated fatty acids. III. Structural determination of cis- and trans-isomers of 3- or 2-alkenoic acids by nuclear magnetic resonance spectroscopy using a chemical shift reagent

Nuclear magnetic resonance spectroscopy with a lanthanide chemical shift reagent was applied for the structural determination of cis-and trans-isomers of 3-alkenoic acids, prepared as substrates for some enzyme reactions related to fatty acid metabolism. The configuration of N-acetylcysteamine derivatives of cis-2-alkenoic acids was also determined by the same technique.
