In an aqueous environment, phospholipids spontaneously arrange into a bilayer. What is the mechanism driving the specific orientation of the fatty acid tails?
Q1. In an aqueous environment, phospholipids spontaneously arrange into a bilayer. What is the mechanism driving the specific orientation of the fatty acid tails?
Answer: Tails facing inward, heads facing outward
Explanation: Hydrophobic tails face inward to avoid water, while hydrophilic heads face the aqueous environment. A single layer would expose tails to water.
