H2HUBB TAKEAWAY
In a laboratory model, the most intense fragments generated by DEA to isolated resveratrol at thermal electron energy are semiquinone anions and neutral hydrogen molecules. The authors concluded that it is suggested that the activity of resveratrol in living cells is driven by dissociative attachment of electrons "leaked" from the respiratory chain to this polyphenolic molecule, followed by the formation of the H₂ antioxidant species inside mitochondria and participation in mitochondrial energy biogenesis. These findings from a laboratory model add evidence supporting molecular hydrogen's biological and therapeutic potential in the model studied.
