am·phi·path·ic

(am'fē-path'ik),
Denoting a molecule, such as comprises detergents or wetting agents, which contains groups with characteristically different properties, for example, both hydrophilic and hydrophobic properties.
Synonym(s): amphiphilic, amphiphobic
[amphi- + G. pathos, feeling]

amphipathic

[-path′ik]
Etymology: Gk, amphi both + pathos suffering
pertaining to a molecule having two sides with characteristically different properties, such as a detergent, which has both a polar (hydrophilic) end and a nonpolar (hydrophobic) end but is long enough so that each end demonstrates its own solubility characteristics.

amphipathic

Of a chemical structure having both hydrophobic and hydrophilic surfaces as in the case of the phospholipid molecules of the cell membrane. Some proteins have amphipathic regions.

amphipathic

a molecule containing both HYDROPHILIC and HYDROPHOBIC components, as in a phospholipid molecule. See FLUID-MOSAIC MODEL.

amphipathic

molecules containing both polar and non-polar regions in their structure.

However, this amphiphile network is reinforced with silica, which limits the swelling capacity both in polar (water) and in nonpolar (chloroform) solvents: 0.
The study demonstrated a "superior" performance in each of these categories and concluded that "representatives of this maltose-neopentyl glycol amphiphile family show favorable behavior relative to conventional detergents, as manifested in multiple membrane protein systems leading to enhanced structural stability and successful crystallization" (Nature Methods, 2010).
All biosurfactants are amphiphiles, which consist of two parts--a polar (hydrophilic) moiety and nonpolar (hydrophobic) group [6].
