Having both hydrophilic ("water loving") and hydrophobic ("water hating") regions within the same molecule. Phospholipids and bile salts are good examples of amphipathic molecules.

(am´ fi path´ ic) [Gr. amphi: both + pathos: emotion] • Of a molecule, having both hydrophilic and hydrophobic regions.

Having both hydrophobic and hydrophilic regions, as in a phospholipid or a detergent molecule.

In the case of surfactants: having both lyophilic and lyophobic groups (properties) in the same molecule. Also referred to as being amphiphilic.

a bio molecule that contains both polar (water friendly) and non-polar (water repelling) domains (Biotech Life Science Dictionary 1998).

a molecule that is "water-loving" (i.e., polar) at one end and "water-hating" (i.e., nonpolar) at the other end; helps hold polar and nonpolar molecules together; characteristic of detergents and of the phospholipid molecules in the membranes of living things

Referring to a molecule or structure that has both a hydrophobic and a hydrophilic part.

denotes a molecule combining hydrophilic and lipophilic ( hydrophobic) properties

having both hydrophobic and hydrophilic regions in a single molecule.
