Phospholipids
Phospholipids and glycolipids consist of two long, nonpolar (hydrophobic) hydrocarbon chains linked to a hydrophilic head group.
The heads of phospholipids are phosphorylated and they consist of either:
-
- Glycerol (and hence the name phosphoglycerides given to this group of lipids).
- Sphingosine (with only one member - sphingomyelin).
