Which of the following large biological molecules will self-assemble into a bilayer when mixed with water?

Question

Quizplus · Accepted Answer

Phospholipids are amphipathic molecules with hydrophilic heads and hydrophobic tails. When mixed with water, they will spontaneously arrange themselves into a bilayer with the hydrophobic tails facing each other on the inside and the hydrophilic heads facing the water on the outside. Proteins, triacylglycerols, and cellulose do not have the same amphipathic properties and do not self-assemble into bilayers.
