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.

Although it is generally accepted that this feature is due to the C–H stretching mode in saturated aliphatic hydrocarbons, the exact nature of this hydrocarbon material remains uncertain (see Pendleton & Allamandola 2002, Pendleton 2004 for recent reviews).

Soluble molecules are numerous and include molecules from many chemical families: for instance aliphatic hydrocarbons, polycyclic aromatic hydrocarbons (PAHs), carboxylic and dicarboxylic acids, amines, and biologically relevant molecules such as amino-acids, sugars (polyols) or nucleobases (purines and pyrimidines).
Meteorites and the physico-chemical conditions in the early solar nebula
The basic structure of IOM is constituted of numerous small aromatic units of 3-4 rings in diameter linked together by small highly ramified aliphatic chains (Gardinier et al. 2000, Cody et al. 2002).
