Why do lipid bilayers form spontaneously?

Question

Quizplus · Accepted Answer

Lipid bilayer formation is exergonic, which means that it releases energy. This is because the hydrophobic tails of the lipid molecules cluster together in a nonpolar environment, leaving the hydrophilic heads exposed to water, which is a polar solvent. This arrangement leads to an increase in entropy, as the hydrophobic tails are no longer constrained by the presence of water, and a decrease in potential energy as the lipid molecules become more ordered. All of these factors contribute to the spontaneous nature of lipid bilayer formation.
