1-Palmitoyl-d9-2-Palmitoyl-sn-glycero-3-PE (Synonyms: 16:0-d9/16:0-PE, 1-Hexadecanoyl-d9-2-Hexadecanoyl-sn-glycero-3-Phosphatidylethanolamine, 1-Hexadecanoyl-d9-2-Hexadecanoyl-sn-glycero-3-Phosphoethanolamine, PE(16:0-d9/16:0))

1-Palmitoyl-d9-2-palmitoyl-sn-glycero-3-PE is intended for use as an internal standard for the quantification of 1,2-dipalmitoyl-sn-glycero-3-PE by GC- or LC-MS. 1,2-Dipalmitoyl-sn-glycero-3-PE (1,2-DPPE) is a naturally occurring PE containing C16:0 fatty acids at the sn-1 and sn-2 positions. It belongs to a class of phospholipids that are the most abundant lipids in the inner leaflet of the plasma membrane.1 1,2-DPPE interacts with cholesterol to form a condensed lipid monolayer with tight hydrogen bonding of the 1,2-DPPE interheadgroups, resulting in a more fluid membrane that may aid in transport and signaling across the bilayer.2,3
