Docosahexaenoic Acid ethyl ester (CAS 81926-94-5)

Docosahexaenoic Acid Ethyl Ester, identified by CAS number 1020718-25-5, is an ethyl ester derivative of Docosahexaenoic Acid (DHA), an omega-3 fatty acid that is vital for maintaining the structural integrity of cell membranes, particularly in the brain and retina. The modification of DHA to its ethyl ester form enhances its stability and solubility, making it more suitable for use in various research settings. In biochemical studies, this compound is used to explore the mechanisms through which omega-3 fatty acids influence cellular functions. Docosahexaenoic Acid Ethyl Ester is particularly valuable in investigations focusing on the modulation of lipid rafts within cellular membranes. These rafts are rich in cholesterol and sphingolipids, and they play critical roles in cell signaling and the organization of membrane proteins. By integrating into these structures, DHA ethyl ester can affect raft fluidity and, consequently, the signaling pathways that depend on these membrane domains. Additionally, research utilizes this compound to study its impact on the expression and activity of enzymes involved in lipid metabolism, such as those in the pathways of inflammation and antioxidant defense. These studies help explain how alterations in lipid composition can affect cellular processes and membrane dynamics, without the direct implications of clinical or therapeutic contexts.
