Low-level chemiluminescence during lipid peroxidations and enzymatic reactions.
Low-level chemiluminescence during lipid peroxidation and enzymatic reaction have been analysed by a filter type spectrometer. Tyrosine and tryptophan residues in proteins were found to be emitters in the visible region during their enzymatic oxidation. The natural chemiluminescence from fertilization of sea urchin eggs was found to have originated from tyrosine--cation radical mediated reaction in ovo-peroxidase--membrane protein--H2O2 system.
