Abstract

The amino acid cysteine is oxidized by horseradish peroxidase, and the water-soluble carotenoid crocin is bleached by cooxidation. The rnonophenol p-hydroxyacetophenone stimulates oxygen uptake, cysteine oxidation and crocin bleaching, whereas its concentration does not change. Superoxide dismutase significantly enhances all these oxidative reactions. Addition of H₂O₂ is not required for these peroxidase-catalyzed oxidations.
