I asked earlier about the reactions that take place in the Folin-Ciocalteu method and I got an answer saying that The mechanism of the Folin-Ciocalteu method involves several sequential reactions:

1. Oxidation of phenolic compounds:

2. Reduction of the Folin-Ciocalteu reagent:

3. Formation of a blue-colored complex:

I'm thanksful for the answer but I need the chemical structures of the substances. And if you can give me some sources I'll be more thanksful.

(Reagent )+( Phenolic compound )( Oxidized reagent )+( Oxidized phenolic compound ) ( Phenolic compound )+( Oxidized reagent )( Reduced reagent )+( Oxidized phenolic compound ) (Oxidized reagent )+( Phenolic compound )( Molybdenum blue complex )
