“…John and Empte have shown that a-tocopherol is oxidized successively to a-tocopherolquinone, a-tocored, and the yellow paraquinone by nitric acid (FIGURE 4). 19 The presence of tocored has been confirmed in our studies by gas chromatog- raphy-mass spectrometry. The identification of the paraquinone remains to be proven.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
