Asymmetry in Synaptic Plasma Membranes. Model of the two leaflets of the plasma membrane, showing the asymmetric distribution of cholesterol and phospholipids. Large globular structures represent proteins. Cholesterol, phosphatidylinositol, phosphatidylethanolamine, and phosphatidylserine are enriched in the cytofacial leaflet. Phosphatidylcholine and sphingomyelin are in abundance in the exofacial leaflet, and there is some phosphatidylcholine in the cytofacial leaflet. + and − denote charge properties of the two leaflets.
