Phospholipids
Phospholipids are a type of lipid, therefore they are formed from the monomer glycerol and fatty acids
Unlike triglycerides, there are only two fatty acids bonded to a glycerol molecule in a phospholipid as one has been replaced by a phosphate ion (PO43-)

As the phosphate is polar it is soluble in water (hydrophilic)
The fatty acid ‘tails’ are non-polar and therefore insoluble in water (hydrophobic)
