Used in research as a deuterated phospholipid analog to study membrane dynamics and lipid-protein interactions. Its deuterated acyl chains allow for precise tracking using techniques like NMR and mass spectrometry. Commonly employed in model membrane systems such as liposomes and bilayers to investigate membrane fluidity, phase behavior, and permeability. Also useful in metabolic studies where stable isotope labeling helps trace lipid processing pathways without altering chemical behavior.
