No one "invented" the pro-oxidant properties of polyphenols. Many polyphenols, it has been observed, are unstable in aqueous solutions (especially those above pH 7.0) and will oxidize to for a phenolic oxidation product as well as hydrogen peroxide (Halliwell, B., 2003. Oxidative strress in cell culture: an under-appreciated problem? FEBS Lett 540, 3-6). This phenomenon has been observed to interfere in enzymatic assays and can be compensated by the addition of catalase, an enzyme which degrades hydrogen peroxide (de Boer, Vincent C.J., 2006 SIRT1 stimulation by polyphenols is affected by their stability and metabolism. Mechanisms of ageing and development 127, 618-627).

What is the difference between polyphenols and phenols?
A phenol is a benzene ring with an hydroxl (OH) group attached. A polyphenol is composed of many such phenols strung together. In terms of everyday life, this description doesn't mean much. A number of fruits and vegetables are being studied based on their polyphenol content, as it's thought that these polyphenols may be responsible for the beneficial effects of these products. Pomegranates and grapes (especially in red wine) are known to be high in polyphenols. Eat your fruits and vegetables.
What are the chemical properties of lansones?
Lansones contain various bioactive compounds such as polyphenols, flavonoids, and triterpenes, which contribute to their antioxidant and anti-inflammatory properties. These compounds also give lansones its potential health benefits, such as improving cardiovascular health and reducing oxidative stress in the body. Additionally, lansones are rich in vitamins and minerals, making them a nutritious fruit option.
What is the specific substances present in gumamela that might have a cooling effect or can heal sunburns?
Gumamela, or Hibiscus rosa-sinensis, contains polyphenols such as flavonoids and anthocyanins that have antioxidant and anti-inflammatory properties, which may help soothe sunburns. Additionally, its mucilage content can provide a cooling effect when applied to the skin.
Modern periodic table is invented by?
The modern periodic table was invented by Dmitri Mendeleev in 1869. Mendeleev organized the elements by increasing atomic mass and grouped them based on similar chemical properties, which laid the foundation for the periodic table we use today.
Is a browning apple core a redox reaction?
Yes, the browning of an apple core is a redox reaction. This process involves the oxidation of the compounds in the apple, such as polyphenols, which leads to the formation of brown pigments.
What are the active medicinal properties of grape skin?
An array of bioflavonoids (quercetin, catechins, flavonols, and anthocyanidins) and nonbioflavonoid polyphenols (acid derivatives), resveratrol.
What does Polyphenols do for your body?
Polyphenols are antioxidants found naturally and reverse damage caused by free radicals.
If someone wanted to learn about polyphenols should they study astronomy physics or chemistry?
If someone wanted to learn about polyphenols they should study bio-chemistry , because polyphenols are polymers of catechin and epicatechin, belonging of the family of condensed tannins.
Why was the triangle invented?
The triangle was not invented. It is the result of observations of physical properties.
What are the active medicinal properties of lemon balm?
Lemon balm contains volatile oils, including citral, citronella, eugenol, and other components as well as flavonoids, triterpenoids, rosmarinic acid, polyphenols, and tannin.

Who invented physical properties?
Physical properties are inherent characteristics of matter that can be observed or measured without changing the substance's identity. They were not invented by any specific individual; rather, they have always existed as properties of matter in the natural world. Scientists and early philosophers have worked over centuries to understand and describe these properties.
Why is a grape green?
Likely because of chlorophyll, polyphenols, and other chemicals.
Was antifreeze invented before cars?
Antifreeze properties of some liquids were known about long before cars were invented.
Which Himalayan tea is best for you?
Himalayan White Tea is known to have a number of nutrients and antimicrobial qualities that safeguard the body against the manifestation of various diseases. It has polyphenols, a group of phytonutrients, and varying levels of catechins, a class of polyphenols.
What are the structure of polyphenols?
Polyphenols are organic compounds characterized by multiple phenol (hydroxyl) groups. They can be classified into several subclasses based on their chemical structure, including flavonoids, phenolic acids, stilbenes, and lignans. The specific structure of a polyphenol molecule will depend on the subclass to which it belongs.
