So cholesterol molecules are relatively large, and these glycophosolipids are also very large, and they're packed densely to this region. That area will have a lower amount of movement. And so if we have lower movement, that means we have more of these interactions. And so that will increase, make that membrane more rigid. Now, on top of that, even though the membrane is more rigid in the presence of cholesterol, what these lipid wraps also do, and what cholesterol does in general, is it basically increases the resistance of the membrane to this transition transition phase that we spoke of earlier. So instead of having this steep slope, the slope is slightly flatter.
