In parallel with the monooxygenase flavonoid 3′-hydroxylase, the enzyme chalcone 3-hydroxylase catalyzes the hydroxylation of the C3-position of the A ring of chalcone.this Additional hydroxyl groups cause changes in light absorption When chalcone accumulates in plants, it causes a slightly different yellow hue.

Why are chalcones colored?

Chalcones are open analogs of flavonoids that provide bright red to purple Different reagents are used to distinguish them from other flavonoids such as flavanones, flavonoids, flavonoids, etc.

What color is chalcone?

This bright yellow Chalcone, found in many plants and certain families, contributes significantly to the pigmentation of the corolla. Chalcone can be synthesized in the laboratory by the aldol condensation of benzaldehyde and acetophenone in the presence of a base (Figure 9.13) [137].

How does chalcone work?

2.5 Anti-inflammatory chalcone

Anti-inflammatory drugs are drugs used to reduce inflammation Reduce pain and inflammation. In other words, these are pain relievers.These drugs work primarily by inhibiting the prostaglandin-producing cyclooxygenases COX-1 and COX-2 [54].

What is chalcone used for?

Chalcone has become the object of continuous attention from academia and industry.Several types of chalcone are now available for treatment Viral diseases, cardiovascular diseases, parasitic infections, pain, gastritis and stomach canceras well as ingredients like food additives and cosmetic formulations.

Where are chalcones found?

Chalcones are polyphenolic compounds of plant origin, commonly found in Edible plants such as tomatoes, apples, licorice, and finger roots. The molecular structure of two aromatic rings consists of three carbon atoms connected to a conjugated carbonyl group and a double bond, resulting in a yellow or orange color for the chalcone.

Why are chalcones yellow to red?

As an intermediate in the subsequent biosynthesis of flavonoids, hydroxychalcone is chemically unstable and rapidly isomerizes to flavanones. …this extra hydroxyl will cause Changes in light absorption When chalcone accumulates in plants, it causes a slightly different yellow hue.
