How do saturated fatty acids influence membrane packing and, consequently, membrane fluidity??

  1. The absence of double bonds allows for a straight structure in the fatty acid tails, promoting tight packing with adjacent lipids.

  1. Saturated fatty acids have a decreased cholesterol content, facilitating close packing with adjacent lipids.

  1. Saturated fatty acids are less polar compared to unsaturated fatty acids.

  1. The absence of double bonds facilitates interaction among the hydrophilic head groups of the lipids.
