Quizplus · Accepted Answer

The outer layer of the plasma membrane of human erythrocytes contains mostly phosphatidylcholine lipids. This is important for maintaining the membrane's structural integrity and fluidity. Additionally, phosphatidylserine and phosphatidylethanolamine are mainly found in the inner layer of the plasma membrane. Phosphatidylinositol is also present in the membrane, but at lower levels compared to phosphatidylcholine.
