Eicosapentaenoic Acid-d5 Ethyl Ester (CAS 86227-47-6 (unlabeled))

Eicosapentaenoic Acid-d5 Ethyl Ester, identified by CAS number 86227-47-6, is a deuterium-labeled derivative of eicosapentaenoic acid (EPA), an omega-3 fatty acid, where five hydrogen atoms have been replaced with the isotope deuterium (D). This modification significantly enhances the molecule′s stability, making it especially useful in analytical chemistry research where precise tracking and measurement of molecular behavior are required. The ethyl ester form of this molecule facilitates its incorporation into lipid assemblies and increases its solubility in organic solvents compared to the free acid form. This property is critical in studies focusing on the dynamics of lipid membranes and lipid-lipid interactions within these structures. Researchers utilize Eicosapentaenoic Acid-d5 Ethyl Ester in mass spectrometry and nuclear magnetic resonance (NMR) spectroscopy to trace the metabolic pathways of EPA in complex lipid systems, understand the mechanism of lipid incorporation into cellular structures, and observe the behavior of fatty acids under various experimental conditions. By using this deuterated compound, scientists can achieve more accurate and detailed insights into the role of EPA in membrane fluidity and function, as well as its interactions with other biomolecules in non-biological systems, without the confounding factors often encountered in biological studies.
