Final answer:
The two tails of the phospholipids are made up of carbon and hydrogen atoms forming non-polar chains. Phospholipids are amphiphilic molecules with a hydrophilic head and two hydrophobic tails.
Step-by-step explanation:
The 2 tails of the phospholipids are long chains of carbon and hydrogen atoms. Because the electrons in these bonds are shared equally, the carbon-hydrogen chains are non-polar. Phospholipids have a unique structure consisting of a hydrophilic head, which includes a phosphate group, and two hydrophobic tails derived from fatty acids. The first fatty acid is usually saturated, while the second is often unsaturated, making the molecule amphiphilic or “dual-loving.” The tails, being devoid of a significant polar charge, do not easily form hydrogen bonds with water.
