Flavonols
From Wikipedia, the free encyclopedia
Flavonols are a class of flavonoids that use the 3-hydroxyflavone backbone (3-hydroxy-2-phenylchromen-4-one (IUPAC)). Their diversity stems from the different positions the phenolic -OH groups.
Some examples include:
- Quercetin (3,3',4',5,7-pentahydroxy-2-phenylchromen-4-one)
- Kaempferol (3,4',5,7-tetrahydroxy-2-phenylchromen-4-one)
- Myricetin (3,,3',4',5',5,7-hexahydroxy-2-phenylchromen-4-one)
- Fisetin (3,3',4',7-tetrahydroxy-2-phenylchromen-4-one)
