a) A schematic illustrating fatty acids are essential components of the different lipid categories as well as eicosanoids. b) IMS analyses of fatty acid standards with different double bond locations and orientations illustrating that double bonds with a cis-orientation have a smaller structure than those with trans-orientations, while saturated FAs have the largest structure. The 3D lowest energy structures of the 18:1 and 18:0 FAs show how the double bond position and orientation impact the size of the FA chain.
