Unformatted text preview: relative long. Short chain FAs tend to increase fluidity of a membrane, whereas long chain FAs tend to decrease the fluidity. Long chain FAs stack together more readily and tend to increase the liquid crystal nature in solution. c) The FAs can vary in the degree and pattern of saturation. Phospholipids with unsaturated FA chains (one or more double bonds) interfere with tight packing of the lipids and thus tend to make the membrane more fluid. Saturated FAs have the opposite effect....
