What is meant by polyphenol?
Polyphenol: A kind of chemical that (at least in theory) may protect against some common health problems and possibly certain effects of aging. Polyphenols act as antioxidants. They protect cells and body chemicals against damage caused by free radicals, reactive atoms that contribute to tissue damage in the body.
What is the role of polyphenols?
Polyphenols are beneficial compounds in many plant foods that can be grouped into flavonoids, phenolic acid, polyphenolic amides, and other polyphenols. They may improve digestion, brain function, and blood sugar levels, as well as protect against blood clots, heart disease, and certain cancers.
What is a polyphenol structure?
Structural chemistry Polyphenols are often larger molecules (macromolecules). Most polyphenols contain repeating phenolic moieties of pyrocatechol, resorcinol, pyrogallol, and phloroglucinol connected by esters (hydrolyzable tannins) or more stable C-C bonds (nonhydrolyzable condensed tannins).
What are polyphenols classification?
Polyphenols are classified on the basis of the number of phenol rings that they contain and of the structural elements that bind these rings to one another. They are broadly dived in four classes; Phenolic acids, flavonoids, stilbenes and lignans.
What are polyphenol foods?
Top Foods with Polyphenols
- Cloves and other seasonings.
- Cocoa powder and dark chocolate.
- Berries.
- Non-berry fruits.
- Beans.
- Nuts.
- Vegetables.
- Soy.
What is the difference between polyphenols and flavonoids?
The key difference between flavonoids and polyphenols is that the flavonoids generally contains a 15-carbon skeleton whereas the polyphenols contain different carbon skeletons. Flavonoids are a group of polyphenols. However, not all polyphenols are flavonoids.
How do polyphenols work?
Polyphenols are reducing agents, and together with other dietary reducing agents, such as vitamin C, vitamin E and carotenoids, referred to as antioxidants, protect the body’s tissues against oxidative stress and associated pathologies such as cancers, coronary heart disease and inflammation.
What are the physiological actions of polyphenols?
Polyphenols have shown the ability to modulate gene expression, induce apoptosis, decrease platelet aggregation, increase blood vessel dilation, modulate intercellular signaling, and modulate enzyme activities associated with carcinogen activation, among other findings.
What are examples of polyphenols?
What are the properties of polyphenols?
The biological properties of polyphenols include anticancer, antioxidant and anti-inflammatory effects. Polyphenols posses anti-microbial and anti-cariogenic properties and is an important source as anti-infective agents against antibiotic-resistant human pathogens.
What do polyphenols do for skin?
Studies have shown that using polyphenols on your skin can protect it from cancer and other forms of sun damage. Polyphenols can also help reverse signs of aging like sun spots, fine lines, and wrinkles—making them a staple in anti-aging products (such as Caudalie Reversatrol Lift Face Lifting Soft Cream).
Where are polyphenols found?
Polyphenols occur naturally, can have antioxidant properties, and are more generally found in fruits, vegetables, cereals, dry legumes, chocolate, and some beverages, oils, and spices.
Which is the best definition of a polyphenol?

Are there any non extractable polyphenols in plant foods?
Nevertheless, polyphenols found in these extracts would correspond only to a fraction of these phytochemicals, the extractable polyphenols (EPP). The extractions leave a residue, commonly neglected, containing an understudied fraction of plant foods polyphenols, the so-called non-extractable polyphenols (NEPP).
