Most common free fatty acids from human serum (see ref (103)): (A) saturated fatty acids, (B) unsaturated 22 carbon long fatty acids, (C) unsaturated 20 carbon long fatty acids, (D) unsaturated 18 carbon long fatty acids, and (E) remaining unsaturated fatty acids. Arrows in panel A show the last carbon atoms; those in panels B, C, and D show the positions of unsaturated bonds. In panel E, the left arrow shows the position of a double bond, while the right arrow shows the last carbon atom.
