15) Lipids, mainly phospholipids, make up the bulk of the cell membrane. How is the structure of the phospholipid so perfectly paired to the function of the cell membrane?
The head of the phospholipid, which is hydrophilic, helps to control the movement of large hydrophobic molecules, and the tails of the phospholipid, which are hydrophobic, help to control the movement of large hydrophilic molecules
