How do integral proteins affect fluidity
WebAt higher cholesterol concentrations: cholesterols will group together and effectively push apart neighboring phospholipid fatty acid tails, decreasing the rigid interactions between … WebLipid molecules become more closely packed and rigid at low temperatures and more fluid at high temperatures. Cholesterol helps maintain the fluidity of the membrane by restraining lipid movement at high temperatures and preventing close packing at low temperatures.
