- Would substances be able to pass through the plasma membrane if the phospholipid tails of the plasma membrane were both saturated fatty acids? No, saturated fatty acids would cause the plasma membrane to loss the fluidity it has by having some unsaturated fatty acids present. No, saturated fatty acids would cause the plasma membrane to be more fluid. Yes, saturated fatty acids would cause the plasma membrane to be a solid versus liquid.
