Question

write briefly the biological role of phenols by biology​

Answer 1

Answer:

Phenolics are able to act as antioxidants in a number of ways. Phenolic hydroxyl groups are good hydrogen donors: hydrogen-donating antioxidants can react with reactive oxygen and reactive nitrogen species [5,6,7,8,9,10,11] in a termination reaction, which breaks the cycle of generation of new radicals

Answer 2

Answer:

Plant phenolic compounds can act as antioxidants, structural polymers (lignin), attractants (flavonoids and carotenoids), UV screens (flavonoids), signal compounds (salicylic acid and flavonoids) and defense response chemicals (tannins and phytoalexins).
