“…Under physiological conditions, double bonds preferably have a cis-configuration, which causes a 30° deflection (curve) of the carbon chain. This results in the cis-unsaturated chain occupying greater space, decreasing van der Waals interactions and thus the melting point 9 . Moreover, the degree of unsaturation (number of double bonds in cis-configuration) significantly influences cell membrane microviscosity and thickness, and consequently also the function of associated proteins (enzymes, cell receptors, membrane transporters and ion channels).…”
