Explain why phospholipids spontaneously form a bilayer when mixed with water?

Phospholipids form a bilayer when mixed with water, since the hydrophilic head is attracted to water, while the hydrophobic tails reject water and tend to aggregate with other hydrophobic molecules, this conflict is resolved with the formation of a lipid bilayer , which satisfies both parties.

They are those that have phosphoric acid in their composition, they are usually amphipathic: their molecules have a part that is soluble in water (that is, hydrophilic) and another that is not (hydrophobic).

Therefore, we can conclude that phospholipids are found in the active membranes of cells whose distinctive feature is they are usually amphipathic.
