Used in research settings to study membrane lipid dynamics and cell signaling pathways. Plays a role in modeling biological membranes due to its polyunsaturated structure, which influences membrane fluidity and domain formation. Commonly employed in liposome formulations to investigate drug delivery mechanisms, especially for targeting neural and retinal tissues where omega-3 fatty acids are biologically relevant. Also utilized in studies examining phospholipase activity and lipid peroxidation due to its susceptibility to enzymatic and oxidative degradation.
