amphipathic

Containing both polar and nonpolar domains. The property of surface activity is usually due to the fact that the molecules of the substance are amphipathic or amphiphilic, meaning that each contains both a hydrophilic and a hydrophobic (lipophilic) group. This assumes that one of the two phases is aqueous, and the other non-aqueous.If both are non-aqueous (e.g. oil/air), molecules containing organophilic and organophobic groups may be amphipathi…
