Benzoquinone is an organic compound which has either of the two isomeric forms of the simplest quinone, CHO, while quinone is an aromatic compound having two carbonyl functional groups in the same six-membered ring.

What does benzoquinone do for plants?

Benzoquinone is toxic to bacteria and helps prevent decay in damaged plant tissue. Benzoquinone has a characteristic brown colour.

Where does hydroquinone come from?

In nature, hydroquinone is produced in the bodies of bombardier beetles, which use the chemical as a defensive secretion. Hydroquinone is also found in plants and fungi, including the poodle-dog bush and the Agaricus hondensis mushroom.

Is hydroquinone the same as quinone?

Quinone is a strong oxidizing agent and is usually reduced to hydroquinone. It has been declared a federal hazardous air pollutant and was identified as a toxic air contaminant in April 1993 under AB 2728. Occupational exposure to quinone may occur in the dye, textile, chemical, tanning, and cosmetic industries.

What is benzoquinone an enzyme?

p-Benzoquinone, a reactive metabolite of benzene, prevents the processing of pre-interleukins-1 alpha and -1 beta to active cytokines by inhibition of the processing enzymes, calpain, and interleukin-1 beta converting enzyme.

Is potato extract an enzyme?

This reaction is catalyzed by catechol oxidase, an enzyme present in potato extract. We expected the product to develop faster at higher temperature, up to a point. Above some optimal temperature, the rate should decrease as the enzyme is distorted or denatured by heat.

Why was hydroquinone banned?

It’s Personal. The recent U.S. ban follows prior bans in other parts of the world like Japan, Australia and Europe. “Hydroquinone has been long banned in Europe because it is cyto-toxic, meaning it is toxic to the cells to prevent making of melanin pigments,” explains cosmetic chemist Ginger King.

What is a natural alternative to hydroquinone?

Other safe, natural alternatives to hydroquinone include brightening ingredients like kojic acid, vitamin C, mushroom, licorice/glycyrrhizin, azelaic acid, and niacinamide (vitamin B3). All of these are key ingredients in our products!

Is hydroquinone safe to use on the face?

The American Osteopathic College of Dermatology (AOCD) suggest that people avoid getting the product in their eyes and only use small amounts on the face. Long-term use of hydroquinone could give rise to ochronosis. Ochronosis causes a blue-black pigmentation and caviar-like spots to develop on the skin.

How does benzoquinone help plants?

Benzoquinone is toxic to bacteria and helps prevent decay in damaged plant tissue.

Why is it important to add the potato extract last?

Why is it necessary to add the potato extract to each tube last, after the water and catechol are already measured? By adding the extract last, we are timing all three tubes to react at the same time.

What happens when you put hydrogen peroxide on a potato?

Catalase, an enzyme found inside a potato, breaks down hydrogen peroxide into water and oxygen gas. The advantage of this reaction is that you can see the oxygen gas bubbling out as it is formed so you can tell how fast the reaction is happening.
