WebMar 13, 2013 · cholesterol resists changes in membrane fluidity with temperature changes due to its steriod rings being bulky and they increase the density of the hydrophobic section of the phospholipid bilayer ... WebSterols such as cholesterol in mammals, ergosterol in fungi, and phytosterols in plants, buffer membrane fluidity and permeability over a broad temperature range. In mammals, cholesterol increases membrane packing to reduce membrane fluidity and permeability. The fatty acids tails of phospholipids also affect membrane fluidity. Fatty acids can ...
