cis-11,14-Eicosadienoic acid ethyl ester (CAS 103213-62-3)

Cis-11,14-Eicosadienoic acid ethyl ester, identified by the CAS number 103213-62-3, is a fatty acid ester characterized by a long-chain eicosadienoic acid bound to an ethyl group. This molecular structure features two double bonds located at the 11th and 14th carbon atoms, both in the cis configuration, which significantly influences its physical and chemical properties. The ethyl ester modification enhances the solubility of the fatty acid in organic solvents compared to its free acid form, making it more suitable for various experimental applications. In research, this compound is particularly valuable for studying the properties and behaviors of unsaturated lipids in membrane systems. The presence of double bonds affects the fluidity and phase behavior of lipid bilayers, which are critical factors in understanding membrane dynamics and function. Researchers utilize cis-11,14-Eicosadienoic acid ethyl ester to investigate these aspects by incorporating it into model membranes or lipid assemblies, thereby gaining insights into how unsaturation levels can impact lipid-lipid and lipid-protein interactions within cellular membranes. Additionally, its use extends to the exploration of lipid oxidation processes, where the susceptibility of unsaturated bonds to oxidative stress can be studied in controlled environments, providing a deeper understanding of lipid peroxidation mechanisms in biological systems.
