Denoting a molecule, such as comprises detergents or wetting agents, which contains groups with characteristically different properties, for example, both hydrophilic and hydrophobic properties.
[amphi- + G. pathos, feeling]
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.
amphipathicOf 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.
amphipathica molecule containing both HYDROPHILIC and HYDROPHOBIC components, as in a phospholipid molecule. See FLUID-MOSAIC MODEL.
molecules containing both polar and non-polar regions in their structure.
