The molecules that prevent cell membranes from dissolving are called lipid molecules most abundantly known as phospholipids.


Picture a lipid molecule as a rectangle. On one end of the rectangle, the bottom of the lipid molecule is hydrophilic, which is the water-loving , polar end of the molecule. On the other end of the rectangle, the head of the lipid molecule is hydrophobic, which is the non-polar and water-fearing end of the molecule.

Within the composition of the protective layer surrounding the outside of the cell, called the cell membrane , there are large amounts of lipid molecules. Phospholipids are the most abundant cell membrane lipids.
