  3. The remaining part of fatty acid, that is hydrocarbon chain is however nonpolar, hydrophobic (Gk. hydro - water, phobes- fear) or water insoluble.
  4. It is soluble in fat solvents and is, therefore, lipophilic.
  5. Substances like fatty acids which have both hydrophilic and hydrophobic components are called amphipathic.
