Evaluate the impact of having one fatty acid versus two fatty acids in membrane lipids on their biological function.

Membrane lipids with one fatty acid are more rigid and less permeable, which is beneficial for structural integrity.

Membrane lipids with two fatty acids are more flexible and permeable, which is beneficial for structural integrity.
