Lipids are molecules that naturally occur.
Some examples are fats, waxes, sterols, and fat solub vitamins. Lipids is a different group of molecules, that use forms of non polymeric monomers. The main function of lipids are to store energy, to signal, and to build a structure for the cell membrane. Lipids may also be defined as hydrophobic, hydrophobic in this case, means to be non-polar. Being non-polar means to have equal sharing of electrons between the two atoms.
