How do polyphenols work?

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.

How does polyphenol act as antioxidant?

Polyphenols have been found to be strong antioxidants that can neutralize free radicals by donating an electron or hydrogen atom. The highly conjugated system and certain hydroxylation patterns such as the 3-hydroxy group in flavonols are considered important in the antioxidant activities.

How do polyphenols reduce inflammation?

Evidence suggests that polyphenols inhibit pro-inflammatory transcription factors by interacting with proteins involved in gene expression and cell signaling, leading to protective effects against many inflammation-mediated chronic diseases (55).

How are polyphenols formed?

Polyphenols are synthesized by plants and widely distributed in plant tissues, where they mainly exist in the form of glycosides. Although basic structures of flavonoids are aglycones (the nonsugar fragment of the corresponding glycoside), flavonoids can be found as glycosides or aglycones.

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. Moreover, flavonoids are naturally occurring compounds while polyphenols can be natural, semi-synthetic or synthetic.

Why do plants produce polyphenols?

All plants produce considerable amounts of polyphenols as secondary metabolites, which then serve as flower pigments, protection from UV light, and defense against the plant’s being eaten.

What are the benefits of polyphenols?

Research shows polyphenols can help manage blood pressure levels and keep your blood vessels healthy and flexible, promoting good circulation. They also help reduce chronic inflammation, another risk factor for heart disease. Polyphenols can reduce and help control your blood sugar levels.

What is the difference between polyphenol and flavonoid?

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.

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 is polyphenols and its importance?

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.
