摘要: Abstract The myoglobin- or peroxidase-catalyzed aerobic oxidation of acetoacetate to methylglyoxal produces a very weak emission. Light production, formation, and O2 uptake strictly correlate with each other. excited species first formed appears be triplet methylglyoxal. Formation the latter is supported by increased light emission observed in presence low concentrations certain sensitizers which contain heavy atoms have low-lying states. In an aprotic solvent emitter results strongly support inference that catalyzing reaction, myoglobin damaged “photochemistry without light” effect. It consequence formation major process.
