Cholesterol Describe Presence Affects Properties Cell Membranes End

Cholesterol stabilizes the phospholipid bilayer and maintains its fluidity by fitting between phospholipids, preventing them from packing too closely at low temperatures and thus avoiding solidification.

El colesterol estabiliza la bicapa fosfolipídica y mantiene su fluidez al encajar entre los fosfolípidos, evitando que se empaqueten demasiado a bajas temperaturas y previniendo la solidificación.

Front Describe how presence of cholesterol affects the properties of cell membranes.
Back Cholesterol in membranes
  • Cholesterol has one end attracted to the polar head of a phospholipid and the tail of another
  • This means cholesterol helps stabilise the bilayer
  • Because it fits between phospholipids it also prevents them from aligning too close together at low temperatures - maintaining fluidity by preventing solidification
