Commonly given citations for the redox potential of ergothioneine are incorrect. In addition, the value of -0.06 V should be viewed with skepticism since the method used to determine the redox potential of ergothioneine was also used to incorrectly determine the redox potential of glutathione. Antioxid. Redox Signal. 38, 1212-1213.
Keywords: ergothioneine; monograph; redox potential.
