It acts as a bidirectional fluidity buffer, restraining phospholipid movement at high temperatures and preventing close packing/crystallization of acyl chains at low temperatures. It permanently solidifies the lipid bilayer at elevated temperatures by covalently cross-linking adjacent sphingolipids and unsaturated fatty acids. It promotes constant passive ion leakage at low temperatures by forming transmembrane aqueous pore complexes across the hydrophobic core. It exclusively increases membrane fluidity at high temperatures by accelerating lateral phospholipid exchange and decreasing transition temperature.
