Phospholipids are large organic molecules with a ________,polar phosphate head connected to ________,nonpolar fatty acid tails.How do these molecules arrange themselves to form a mostly impermeable barrier between a liposome and its environment?

Question

Quizplus · Accepted Answer

Phospholipids have hydrophilic heads and hydrophobic tails. To form a barrier, they arrange themselves in a bilayer with the hydrophobic tails facing each other towards the center of the membrane and the hydrophilic heads facing outward, away from the center line of the membrane. This arrangement creates a mostly impermeable barrier between the liposome and its environment.
