Cholesterol Fluidity Phospholipids Bilayer Preventing End Interacts Explain

Front Explain how cholesterol affects the fluidity and stability of membranes.
Back Effect of cholesterol on membranes:
  • Chol molecules are positioned between phospholipids in the bilayer preventing them from aligning too closely together and therefore preventing solidification - maintains fluidity
  • Hydrophilic end interacts with the heads and hydrophobic end interacts with tails, pulling them together - stabilises bilayer as it is attracted to the phospholipids
