These complexes, in turn, form these lipid ramps. And what that does is it makes the membrane slightly less fluid, so more rigid, but at the same time, it makes it much more resistant to actually phase transitions. And so when there's a change in temperature taking place, that membrane is less likely to actually transition between these two stages. And that's very important to maintaining homeostasis inside the cells of our body. So cholesterol is basically used in animal cells, in our own cells to regulate the fluidity of the membrane and is also used to basically regulate the transition from the rigid state to the fluid state or vice versa. So we conclude that there are three different things that basically allow the that basically influence the fluidity of the membrane.
