The geometry of the double bond is almost always a cis configuration in natural fatty acids<span>. These molecules </span>do<span> not "stack" very well. The intermolecular interactions are much weaker than </span>saturated <span>molecules. As a result, the melting </span>points<span> are much </span>lower<span> for </span>unsaturated fatty acids<span>.
