Eicosapentaenoic Acid-d5 (CAS 1197205-73-4)

Eicosapentaenoic Acid-d5, referred to by the CAS number 1197205-73-4, is a deuterated form of eicosapentaenoic acid (EPA), an omega-3 fatty acid naturally found in marine oils. In this molecule, specific hydrogen atoms are replaced with deuterium, a heavier isotope of hydrogen, which is a common modification used in research to study metabolic processes involving lipids due to the isotopic labeling. This subtle modification allows researchers to trace the metabolic pathways and degradation of EPA without altering its chemical nature significantly. Eicosapentaenoic Acid-d5 is particularly valuable in studies focused on understanding the biochemical role of EPA in various non-medical biological processes, such as its incorporation into cell membranes and its conversion into other biologically active molecules. By using mass spectrometry and other analytical techniques that can detect the presence of deuterium, scientists can precisely monitor the fate of the molecule in experimental settings, offering insights into lipid metabolism, signaling pathways, and cellular mechanisms. This approach is crucial for elucidating the fundamental roles of fatty acids in cell structure and function, and in broader biological systems, thereby aiding in the exploration of lipidomics and the complex interaction network of cellular lipids.
