ω-3 Arachidonic Acid ethyl ester (CAS 123940-93-2)

ω-3 Arachidonic Acid ethyl ester, with the CAS number 123940-93-2, is a chemically modified form of arachidonic acid, an essential polyunsaturated omega-6 fatty acid. This specific ethyl ester variant is structured to enhance the stability and solubility of arachidonic acid in various experimental contexts. In research environments, this compound is particularly valued for its role in the study of lipid metabolism and signaling pathways. The ethyl ester form allows for easier incorporation into cell membranes and can influence the activity of various enzymes and receptors involved in lipid signaling processes. Mechanistically, ω-3 Arachidonic Acid ethyl ester participates in the biosynthesis of eicosanoids, which are signaling molecules that play critical roles in modulating inflammation and cellular homeostasis. This compound is often used in experimental setups to investigate the dynamics of fatty acid incorporation into cellular lipids and the resultant effects on cell function. By altering the fatty acid composition of membranes, researchers can explore how these changes affect the physical properties of membranes and their biological functions, such as fluidity, signaling capabilities, and the interaction with proteins. This research has significant implications for understanding the fundamental aspects of cell biology and the complex web of metabolic and signaling pathways in which fatty acids are involved.
