Coenzyme Qs , which are distributed in virtually all living cell membranes, shuttle electrons in the respiratory chain using their redox quinonyl group. In their Full paper on page 1064 ff., Y.‐T. Long et al. report a newly synthesized methylene‐bridged bis‐Coenzyme Q 0 , bis(2,3‐dimethoxy‐5‐methyl‐l,4‐ benzoquinone)methane (Bis‐CoQ 0 ), which couples two Coenzyme Q 0 monomers through a short methylene bridge. Intramolecular electronic communication between the two redox‐active quinones enables three‐step four‐electron transfer processes in non‐aqueous solvent. Bis‐CoQ 0 shows a significant effect on potentiating the cellular antioxidant defense capacity.
