(ŭn-sach'ŭr-āt'ĕd),
1. Not saturated; denoting a solution in which the solvent is capable of dissolving more of the solute.
2. Denoting a chemical compound in which all the affinities are not satisfied, so that still other atoms or radicals may be added to it.
3. In organic chemistry, denoting compounds containing double and/or triple bonds or a ring structure.

unsaturated

(ŭn-săch′ə-rā′tĭd)

unsaturated

Pertaining to a compound, especially of carbon, in which atoms are linked by double or triple valence bonds. A saturated compound has only single bonds. In general, unsaturated compounds are less stable than saturated compounds and can undergo a wider variety of reactions.
