MEMBRANE FLUIDITY I. Membrane fluidity is controlled by fatty acids composition and cholesterol content II. Fatty acid chains in membrane bilayers can exist as an ordered, rigid state or in a relatively disordered, fluid state. III. The transition from rigid to fluid state takes place abruptly as the temperature is loweree below the melting temperature IV. The presence of saturated acid residues favors the fluid state because their straight chain HC chains interact favorably with one another.
