lipid bilayer

The two layers of phospholipid molecules included within the outer membrane of most cells. These layers are arranged so their two hydrophilic (water-soluble) sides face the interior and the exterior of the cell, and their hydrophobic (nonpolar) core is in between. The membrane is relatively impermeable to molecules such as glucose and amino acids but very permeable to lipid-soluble molecules such as oxygen, carbon dioxide, and alcohol.
