Phospholipids are a type of lipid (fat) that contains one or more phosphate groups in the chemical structure.
Phospholipids have one end that is hydrophilic (water loving) and the other end that is hydrophobic (water fearing).
There are two types of phospholipids:
- Containing a glycerol backbone
- Containing sphigosine
- Lecithin is the most common form of phospholipid
- A common phospholipid is phosphatidylcholine
Why phospholipids are important
Cell membranes have a phospholipid bi-layer which means that the contents within the cell cannot spill out and none of the exterior can enter the cell (unless required).
The phospholipid bi-layer also allows cells to be flexible and not rigid, which is a beneficial property for cells.
