Living organisms also contain a lot of hydrogen, oxygen, nitrogen, sulfur, and phosphorous. Those atoms combine together to form complex molecules of various types: proteins, carbohydrates, lipids, and nucleic acids.
More fluid bilayers will be formed when the saturation of the fatty acids chains on a phospholipid is decreased.
Fatty acids are present in animals, plants and other microorganisms. They are composed of the carbon chain with carboxyl group at the end of the chain. The fatty acids are the vital components of the lipids, which are the essential fat soluble components. When the saturation level of these acids is decreased, it leads to the formation of more lipid bilayers.
Hence, the correct answer is 'more fluid bilayers'.
A. Dietary and functional fiber
