Phospholipids are amphipathic molecules, meaning they have a hydrophobic (non-polar) tail and a hydrophilic (polar) head. This structure allows them to pack together in a double layer, with the hydrophobic tails pointing inward and the hydrophilic heads facing outward towards the aqueous environment.
