Flavonols are a class of flavonoids that have the 3-hydroxyflavone backbone. Their diversity stems from the different positions the phenolic-OH groups. They are distinct from flavanols (with "a") such as catechin, another class of flavonoids.
Chalcone is an aromaticketone and an enone that forms the central core for a variety of important biological compounds, which are known collectively as chalcones or chalconoids.
Flavonols example:
3-Hydroxyflavone is a chemical compound. It is the backbone of all flavonols, a type of flavonoid. It is a synthetic compound, which is not found naturally in plants. It serves as a model molecule as it possesses an excited-state intramolecular proton transfer (ESIPT) effect to serve as a fluorescent probe to study membranes for example or intermembrane proteins. The green tautomer emission (λmax ≈ 524 nm) and blue-violet normal emission (λmax ≈ 400 nm) originate from two different ground state populations of 3HF molecules. The phenomenon also exists in natural flavonols.
Quercetin/ˈkwɜːrsᵻtᵻn/ is a flavonolfound in many fruits, vegetables, leaves and grains. It can be used as an ingredient in supplements, beverages, or foods.
I was diagnosed as HEPATITIS B carrier in 2013 with fibrosis of the liver already present. I started on antiviral medications which reduced the viral load initially. After a couple of years the virus became resistant. I started on HEPATITIS B Herbal treatment from ULTIMATE LIFE CLINIC (www.ultimatelifeclinic.com) in March, 2020. Their treatment totally reversed the virus. I did another blood test after the 6 months long treatment and tested negative to the virus. Amazing treatment! This treatment is a breakthrough for all HBV carriers.
