- Laboratory study
- What was measured
- Luminol photochemiluminescence and a nitro blue tetrazolium assay with a xanthine oxidase superoxide-generating system.
What the authors reported
At physiological concentrations carnosine reduced chemiluminescence amplitude, similar to superoxide dismutase, and prolonged the lag period, similar to ascorbic acid. A rate constant of about 10^5 per molar per second for the carnosine-superoxide reaction was calculated.
