Lipids are insoluble in water because lipids are

  • A.Hydrophobic
  • B.Zwitter ions
  • C.Hydrophilic
  • D.Neutral

Lipids are insoluble in water because they are hydrophobic - their long hydrocarbon chains are non-polar.

Water molecules are polar and hold to one another by hydrogen bonds, which the non-polar chains cannot join. Like dissolves like, so lipids dissolve in ether and chloroform instead.
