Antioxidants play an indispensable role in mitigating oxidative stress by neutralising free radicals through a series of interrelated electron transfer reactions. Among the principal mechanisms are ...

The hydrogen atoms of [4Fe-4S] type ferredoxin, one of the electron carriers, have been visualized and both experiments and calculations have revealed the mechanisms that control the redox potential.

Excited-state intramolecular proton transfer (ESIPT) is a compelling photochemical process whereby a proton relocates within a molecule following photoexcitation. This intramolecular rearrangement is ...

A group of researchers in Japan has revealed, for the first time, a mechanism for controlling the potential of an “electron carrier” protein in the redox reaction that all organisms need to obtain ...
