    • adj aliphatic having carbon atoms linked in open chains
    • ***
Webster's Revised Unabridged Dictionary
    • a Aliphatic (Org. Chem) Of, pertaining to, or derived from, fat; fatty; -- applied to compounds having an open-chain structure. The aliphatic compounds thus include not only the fatty acids and other derivatives of the paraffin hydrocarbons, but also unsaturated compounds, as the ethylene and acetylene series. Compare alicyclic and aromatic.

Century Dictionary and Cyclopedia
    • aliphatic Of or pertaining to fat; fatty; specifically, in chem., designating compounds which have only an open chain of carbon atoms, as distinguished especially from aromatic compounds, which contain a ring of carbon atoms, he natural fats consist chiefly of compounds of this type.
