On the other hand, the introduction of one or more double bonds in the hydrocarbon chain in unsaturated fatty acids results in one or more hplc "bends" in the molecule. hplc The geometry of the double bond is almost always a cis configuration in natural fatty acids. These molecules do not "stack" very well. The intermolecular interactions are much weaker than hplc saturated molecules. As a result, the melting points are much lower for unsaturated fatty acids.
