Summary:
- A phospholipid is a lipid that contains a phosphate group and is a major component of cell membranes.
- A phospholips consists of a hydrophilic (water-loving) head and hydrophobic ( water-fearing) tail.
- In a water solution, phospholiptids form a bilayer where the hydrophobia tails point towards each other on the interior.
- This is accomplished by the embedding of various protein molecules in and through the lipid bilayer.
- These proteins form channels through which certain specific ions and molecules are able to move.
