The Components and Functions of the Plasma MembraneĪttached between phospholipids and between the two phospholipid layers The mitochondrial inner membrane contains 76% protein and 24% lipid. For example, myelin contains 18% protein and 76% lipid. The proportions of proteins, lipids, and carbohydrates in the plasma membrane vary with cell type. For comparison, human red blood cells, visible via light microscopy, are approximately 8 µm wide, or approximately 1,000 times wider than a plasma membrane. Plasma membranes range from 5 to 10 nm in thickness. The fluid mosaic model describes the structure of the plasma membrane as a mosaic of components – including phospholipids, cholesterol, proteins, and carbohydrates – that gives the membrane a fluid character. The model has evolved somewhat over time, but it still best accounts for the structure and functions of the plasma membrane as we now understand them.
