Particularly abundant flavanoids in foods are catechin (tea, fruits), hesperetin (citrus fruits), cyanidin (red fruits and berries), daidzein , proanthocyanidins (apple, grape, cocoa), and quercetin (onion, tea, apples). [2] Phenolic acids include caffeic acid; Lignans are polyphenols derived from phenylalanine found in flax seed and other cereals.
Organisms sometimes synthesize phenolic compounds in response to ecological pressures such as pathogen and insect attack, UV radiation and wounding. [5] As they are present in food consumed in human diets and in plants used in traditional medicine of several cultures, their role in human health and disease is a subject of research.
Specifically, berries are high in phenolic compounds, including anthocyanins and flavonols, which have been linked with benefits for brain, eye, heart and metabolic health.
The phenolic compounds and saponins in quinoa may help reduce the risk of cardiovascular disease and diabetes, and its soluble fiber helps decrease triglycerides and LDL levels in the body while ...
In organic chemistry, phenols, sometimes called phenolics, are a class of chemical compounds consisting of one or more hydroxyl groups (−O H) bonded directly to an aromatic hydrocarbon group. [1] The simplest is phenol, C 6 H 5 OH. Phenolic compounds are classified as simple phenols or polyphenols based on the number of phenol units in the ...
The three flavonoid classes above are all ketone-containing compounds and as such, anthoxanthins (flavones and flavonols). [1] This class was the first to be termed bioflavonoids. The terms flavonoid and bioflavonoid have also been more loosely used to describe non-ketone polyhydroxy polyphenol compounds, which are more specifically termed ...
