The phospholipid bilayer is made out of a hydrophobic tail and a hydrophilic head. Since the hydrophilic tails interact poorly with water, this results in the tails facing inwards as they are repelled from water and thus form the centre of the bilayer. Therefore, the centre of a bilayer is hydrophobic.

Phospholipid bilayers have a hydrophilic head and hydrophobic tail.


Hydrophobic fatty acid tails are hydrocarbon chains and are positioned towards each other (so is in the centre). Therefore, the hydrophilic heads face outwards (extracellular).

Hydrophobic. By facing inwards the hydrophobic tails of phospholipids don't come into contact with water in the cell fluid inside or liquids like blood outside.

The centre of a bilayer is hydrophobic, because the "tail" end is made of two fatty acid chains, and fatty acids don't dissolve in water (=hydrophobic). If you fill a glass with water and add oil, you will see that the oil floats on top. This is because oils and fatty acids are hydrophobic.

Hydrophobic. The tails of the phosphlipids ‘dislike’ water, therefore form the bilayer structure with other phospholipids.

The centre of the phospholipid bilayer is hydrophobic. This is because the head of the bilayer is hydrophilic whereas the tails are hydrophobic.
