"Each person's metabolism is different, and some people may form more vitamin E quinone than others."

It is one of the two isomers of quinone, the other being 1,4-benzoquinone.

A proton motive force is generated using only the quinone pool.

In strongly basic medium and the presence of air it is oxidized to a quinone.

Several isomers are possible, each of which can be viewed as a quinone derivative.

Chemically, idebenone is an organic compound of the quinone family.

As the researchers report in the journal Science, the pheromone is gentisyl quinone isovalerate.

In these reactions, the amine displaces chloride from the ring of the quinone.

Benzoquinone is a quinone with a single benzene ring, of which there are only two:

In the example below, demethylation affords a quinone.

Reduction of quinone reverses this reaction back to hydroquinone.

But to their astonishment, only one chemical in the broccoli broth caused quinone reductase to soar.

The data in Table 3indicate, however, a cellular accumulation of only about 0.03 nmoles of alpha-tocopheryl quinone.

Some dehydrogenases are also proton pumps; others funnel electrons into the quinone pool.

Quinone is reduced to a semiquinone radical anion.

An overload of vitamin E quinone could result in excessive bleeding or even trigger a hemorrhagic stroke.

However, the data in Table 3show that gamma-tocopherol does not slow the oxidation of alpha-tocopherol to alpha-tocopheryl quinone.
