Question

Quizplus · Accepted Answer

Phosphatidylethanolamine (PE) and phosphatidylserine (PS) are the phospholipids that are predominantly found in the inner layer of the lipid bilayer. PE has a small head group and makes the membrane more fluid, while PS carries a negative charge and plays a role in cell signaling processes. SM (sphingomyelin) is not typically found in the inner layer and PC (phosphatidylcholine) is more evenly distributed between the inner and outer layers of the lipid bilayer.
