Phospholipids are amphiphilic

Amphiphil (noun: amphiphilia) (from ancient Greek ἀμφί amphí “on both sides” and φίλος phílos “loving”), ambiphilic (noun: ambiphilia; mixed word from ambi Latin and phil ancient Greek with the literal meaning “both loving”) and amphipathic describe the chemical Property of a substance that is both hydrophilic and lipophilic . This means that it is readily soluble in both polar solvents and non-polar solvents. This is based on the fact that the molecules have both hydrophilic and hydrophobic areas. The best known polar solvent is water , hence the name hydrophilic. One type of hydrophobicity can be that the substance dissolves well in fats or oils ; it is then called lipophilic . The HLB value is a measure of the amphiphilic properties of a molecule.

Important amphiphilic substances are

An important property of amphiphilic substances is the formation of micelles and liposomes (simple form of a biomembrane ).
