What are the characteristics of flavonoids?
Flavonoids are defined as polyphenolic compounds by virtue of their chemical structure which contains two phenyl rings linked by a propane bridge resulting in the characteristic 15-carbon (C6–C3–C6) flavan skeleton (Neilson & Ferruzzi, 2012).
What is the structure of flavonoids?
Chemically, flavonoids have the general structure of a 15-carbon skeleton, which consists of two phenyl rings (A and B) and a heterocyclic ring (C, the ring containing the embedded oxygen). This carbon structure can be abbreviated C6-C3-C6.
How do you synthesize flavonoids?
Flavonoids are synthesized by the phenylpropanoid metabolic pathway in which the amino acid phenylalanine is used to produce 4-coumaroyl-CoA. This can be combined with malonyl-CoA to yield the true backbone of flavonoids, a group of compounds called chalcones, which contain two phenyl rings.
What is the function of flavonoids in plants?
Flavonoids are structurally diverse secondary metabolites in plants, with a multitude of functions. These span from functions in regulating plant development, pigmentation, and UV protection, to an array of roles in defence and signalling between plants and microorganisms.
Are flavonoids bad for your health?
Flavonoids are rich in antioxidant activity and can help your body ward off everyday toxins. Including more flavonoids in your diet is a great way to help your body stay healthy and potentially decrease your risk of some chronic health conditions.
How are flavonoids and antioxidants related to each other?
This review article discusses the biological properties of the flavonoids and focuses on the relationship between their antioxidant activity, as hydrogen donating free radical scavengers, and their chemical structures. This culminates in a proposed hierarchy of antioxidant activity in the aqueous phase.
Are there any bioactive flavonoids in medicinal plants?
Bioactive flavonoids in medicinal plants: Structure, activity and biological fate. Abstract. Flavonoids, a class of polyphenol secondary metabolites, are presented broadly in plants and diets. They are believed to have various bioactive effects including anti-viral, anti-inflammatory, cardioprotective, anti-diabetic, anti-cancer, anti-aging, etc.
Why do flavonoids act as free radical scavengers?
Within the antioxidant mechanisms of the flavonoids it has been noted that they act as free radical scavengers, an activity that they present because they have a stabilized structure that allows them to attenuate the highly reactive free radicals, becoming less reactive aroxyl radicals.
How does flavonoid interact with different therapeutic targets?
Different studies have shown that flavonoids can interact with different therapeutic targets, this ability to interact is mainly influenced by its chemical structure and redox capacity.
