#BioDub Candy Corn-Lipid Billayer/Cell Membrane Analogy

Each candy corn represents one phospholipid. The white end is "afraid" of water (hydrophobic). The Yellow end is not "afraid of water (hydrophilic). The only way the lipid molecules can arrange themselves, to protect the hydrophobic portion of the molecule both in and outside the cell, is to create two layers, back-to-back.
