Websurface. An enzyme active toward the ortho and para‐diphenol groups, including mono‐, di‐ and polyphenols, aminophenols, or methoxyphenols, is laccase (Lac) [40]. Lac was used in biosensors based on metallic nanoparticles [41], carbon nanomaterials [42], polymers, WebAmong the colored products from the oxidation of phenol by chromic acid is the dicarbonyl compound para-benzoquinone (also known as 1,4-benzoquinone or simply quinone); an ortho isomer is also known. These compounds are easily reduced to their dihydroxybenzene analogs, and it is from these compounds that quinones are best prepared.
