In the plasma membrane, the Write Me an Essay outward-facing hemicapa contains a majority of the lipids that have choline, such as phosphatidyl choline and sphingomyelin, while phosphatidyl ethanolamine, phosphatidyl inositol and phosphatidyl serine are preferably located in the internal hemicapa. This is interesting because they create a different distribution of charges between both surfaces of the membrane, which contributes to the membrane potential.
The generation and maintenance of this asymmetry is essential for the cell.
