Used primarily in the formulation of liposomes for drug delivery systems, especially in targeted cancer therapies. Its structural properties enhance membrane stability and prolong circulation time in the bloodstream. Frequently employed in PEGylated liposomal formulations to reduce immune recognition and improve drug retention. Also utilized in research settings to study membrane dynamics and lipid bilayer behavior. Common in nanomedicine for encapsulating chemotherapeutic agents, enabling controlled release and improved therapeutic efficacy.
