What chemical property characterizes ; the interior of the phospholipid bilayer? It is hydrophobic. It is hydrophilic. It is polar. It is saturated.

The correct answer is: It is hydrophobic.<br /><br />The interior of the phospholipid bilayer is characterized by being hydrophobic. This means that it repels water and is not attracted to it. The hydrophobic tails of the phospholipids face inward, away from the aqueous environment, forming the interior of the bilayer. This hydrophobic characteristic helps to create a barrier that separates the interior of the cell from the external environment.
