How do cholesterol molecules affect fluidity?


The effect of cholesterol in high temperature and low temperature comes down to how extensively the fatty acid tails are moving in all those phospholipids, and what the consequence is of wedging cholesterol molecules in among those tails. Do they interact less with their neighbors? If so, you've increased fluidity. Do they interact more with their neighbors? If so, you've increased stability.
