Cholesterol is an example of an amphipathic molecule, whereas all the above options affect membrane fluidity.
<h3>What is an amphipathic molecule?</h3>
An amphipathic molecule is a compound that has a hydrophilic region and a hydrophobic region.
Phospholipids are the main constituent of the cell membrane and this lipid matrix.
The number of double bonds in hydrocarbon tails affects membrane fluidity by generating a "kink" in the fatty acid chains.
Cholesterol content alters fluidity because this lipid has free movement in the membrane.
Phospholipids and steroids such as cholesterol are amphipathic molecules, whereas membrane fluidity refers to the movement of the constituents of the cell membrane.
In conclusion, Cholesterol is an example of an amphipathic molecule, whereas all the above options affect membrane fluidity.
