18:2 PS (1,2-dilinoleoyl-sn-glycero-3-phospho-L-serine, sodium salt) is a phospholipid belonging to the phosphatidylserine (PS) class. It contains two linoleic acid (18:2) chains at the sn-1 and sn-2 positions. This compound is widely used in research to study various biological processes, including membrane dynamics, signal transduction, and protein-lipid interactions. Due to its amphipathic nature, 18:2 PS is also utilized in the development of liposomal formulations for drug and gene delivery, offering potential applications in targeted therapy and delivery systems.
