Cholesterol is a normal component of cell membranes.
Cholelsterol stiffens the outer parts of the phospholipid tails, thus making the membrane less fluid. So it lowers membrane fluidity, but widens the temperature range over which the membrane remains fluid. Identify the fatty acids in these PC molecules. Each molecule has two different fatty acids esterified to it. Display cholesterol and PC together.
