There are two main differences. • Phospholipids have a phosphate (PO4) group attached to the glycerol head in place of one phospholipid. Triglycerides do not have this phosphate group. • Triglycerides have 3 fatty acids attached to a glycerol head, Phospholipids only have 2 fatty acids attached to a glycerol head •Triglycerides are non polar be are completely hydrophobic (insoluble in water. Phospholipids have a hydrophilic phosphate head which allows them to interact with water. This is why Phospholipids are so important in the cell membrane as much of the cytoplasm and extracellular environment contains water. Both contain fatty acids, both contain phospholipids
