they are sandwiched between two layers of heads
Lipids with polar heads and nonpolar tails are called phospholipids. They are a major component of cell membranes, with the polar heads facing the aqueous environment and the nonpolar tails forming the interior of the membrane.
they have a polar head and non-polar tails
Tails are Hydrophobic
False. The cell membrane is actually formed by phospholipids with hydrophilic heads facing outward towards the extracellular fluid and cytoplasm, while the hydrophobic fatty acid tails are sandwiched in between.

False. The cell membrane is actually formed by phospholipids with hydrophilic heads facing outward towards the extracellular fluid and cytoplasm, while the hydrophobic fatty acid tails are sandwiched in between.
The dual nature of phospholipids, with hydrophilic heads and hydrophobic tails, is most important for the formation of bilayers. This allows them to self-assemble in water to form the lipid bilayer structure found in cell membranes.
The water-insoluble hydrophobic tails of phospholipids in the lipid bilayer are oriented towards the interior of the membrane, away from the surrounding water. This arrangement helps to shield the hydrophobic tails from the polar environment outside the cell membrane.
They avoid water. (The word "hydrophobic" literally means "water-fearing" :D )
