    Cholesterol is found in the plasma membrane naturally. Depending on the body’s cholesterol levels, the plasma membrane will either have a low, normal, or high amount of cholesterol in the membrane.

    Cholesterol is a molecule that adds rigidity to the plasma membrane, therefore a normal amount is good for the membrane, because it keeps it from being too flimsy. However, too much can cause cells to be too rigid, like the cells in the walls of arteries. If they get too stiff due to high cholesterol it can cause blood pressure problems.

    High cholesterol has a lot of negative affects, not only just on the plasma membrane, but on organs and tissues as a whole.
