| Chemiluminescence in the Coupled Oxidation of Lecithin and Ascorbate  | | | | Abstract
| Chem ilum inescence (CL) that appears during oxidation o f lecithin and ascorbate has been studied. A simple system consisting only o f purified lecithin, which has one double bond, and ascorbate as a physiological reductant with a low redox potential, was used. The CL spectrum o f lecithin contain a strong band lying in the near infrared, and three bands at 20 900 cm -1, 17 700 cm -1 and 15 800 cm -1, being characteristic o f singlet m olecular oxygen (1O a). The effect o f * 0 2 quenchers on both autooxidation processes has also been investigated. The obtained results indicate that the main emitter is the *0 2. An addition o f ascorbate to the system lecithin plus buffer causes a decrease o f CL intensity. That is a result o f stronger quenching properties o f ascorbate and not due to efficiency o f the generation o f *0 2 . | | | |
