What Are Polyphenols?
Share
Polyphenols are a diverse group of compounds that can be broadly classified into several subgroups based on their chemical structure. These subgroups include:
-
Flavonoids: Flavonoids are the most well-known and studied subgroup of polyphenols. They include compounds such as quercetin, catechins, and anthocyanins. They are characterized by a basic flavonoid skeleton, which consists of 15 atoms and includes two aromatic rings (A and B) joined by a three-carbon linker (C).
-
Phenolic acids: Phenolic acids are another subgroup of polyphenols. They include compounds such as ferulic acid, caffeic acid, and chlorogenic acid. They are characterized by a hydroxybenzoic acid or hydroxycinnamic acid structure.
-
Lignans: Lignans are a class of polyphenols found in seeds, whole grains, fruits, and vegetables. They include compounds such as enterolactone and enterodiol. They are characterized by a lignan skeleton, which is a complex ring structure that includes a phenylpropane unit.
-
Stilbenes: Stilbenes are a class of polyphenols that are characterized by a stilbene skeleton, which is a molecule composed of two phenyl rings linked by a double bond. They include compounds such as resveratrol and pterostilbene.
-
Tannins: Tannins are a subgroup of polyphenols characterized by their ability to bind to proteins, which can cause them to precipitate or aggregate. They include compounds such as catechins, flavanols, and proanthocyanidins.
Each subgroup of polyphenols have their own specific chemical structures and properties and therefore have different health benefits. It is also important to note that the chemical structure of a polyphenol can affect its bioavailability and its potential health effects.
Sachi Inchi is high in various polyphenols and therefore a vital addition to any plant-based diet.
