The formation of isovaleraldehyde from ℓ-leucine and isobutyraldehyde from ℓ-valine catalyzed by banana polyphenoloxidase and peroxidase
… oxidation of dopamine to o-quinones catalyzed by polyphenoloxidase and peroxidase, followed by the nonenzymic reaction of the quinone with the amino acid to form the corresponding aldehyde. At levels of leucine, polyphenoloxidase (PPO) and dopamine tested, aldehyde production increased with …
