5,7-Eicosadiynoic acid (CAS 69288-29-5)

5,7-Eicosadiynoic acid, with the CAS number 69288-29-5, is a unique polyunsaturated fatty acid characterized by having two triple bonds located at the 5th and 7th positions of its carbon chain. This structural element differentiates it from typical polyunsaturated fatty acids, which generally contain double bonds, and confers distinct physical and chemical properties. In research, this acid has been instrumental in studying the impact of triple bonds within fatty acids on the biophysical properties of cell membranes, including permeability and fluidity. The presence of triple bonds significantly affects the way this fatty acid interacts with lipid bilayers and other membrane components, which is critical for understanding membrane dynamics and stability under various physiological conditions. Additionally, 5,7-Eicosadiynoic acid has been used as a probe in biochemical studies exploring the mechanisms of lipid oxidation and its consequences on cellular integrity and signaling. Its unique reactivity due to the triple bonds has also made it a subject in synthetic chemistry research, where it has been explored as a precursor or intermediate in the synthesis of complex organic compounds. Through these diverse applications, 5,7-Eicosadiynoic acid contributes broadly to the fields of membrane biophysics, organic synthesis, and lipid biochemistry, enhancing our understanding of the complex behaviors of lipids in biological systems.
