The hydrophilic phosphate heads like water, so they touch the inside and the outside of the cell where the environments are aqueous. The fatty acid tails form a hydrophobic region in the middle, which is free of water.This cell membrane helps in structuring the cell and also controls which substances can cross it.o do hydrophilic molecules. Therefore, the hydrophobic tails of a phospholipid would want to stay with the oil layer of the salad dressing, while the hydrophilic head of the phospholipid would be attracted to the water layer. It would look like the phospholipid was doing a hand stand in the salad dressing.
