DPPE is a natural PE containing 16:0 fatty acids at the sn-1 and sn-2 positions. It belongs to a class of phospholipids and is the most abundant lipid in the inner leaves of the plasma membrane. The interaction between 1,2-DPPE and cholesterol forms a condensed lipid monolayer, where the head end groups of 1,2-DPPE have tight hydrogen bonds, forming a more fluid membrane that may facilitate transport and signal transduction across the bilayer.

DPPE是一种在 sn-1 和 sn-2 位置含有 16:0 脂肪酸的天然 PE。 它属于一类磷脂,是质膜内叶中含量**的脂质。 1,2-DPPE 与胆固醇相互作用形成凝聚的脂质单层,其中 1,2-DPPE 头端间基团具有紧密的氢键,从而形成更流动的膜,可能有助于跨双层的转运和信号传导。
