Analysis of oxidation in aqueous and alcoholic solvents revealed that the chromane ring is broken upon oxidation, and Trolox quinone with two C=O groups is formed (Equation (12)), resulting in two electron oxidation [32]:
Trolox is formally a compound with one OH group; however, when hydrolysis of the ether bond in the chromane ring resulting in the formation of 1,4-hydroquinone is taken into the account, it is oxidized as a typical diphenolic compound (Equation (10)) with one electron exchanged per OH group.
Comments: A Chromane that protects biomolecules and cellular functions from the damage caused by the reactive species generated from air pollution or UV radiation, as well as from endogenous sources, consequently preventing the premature signs of aging.
