摘要: Efficient excited state formation - much higher than that hitherto expected may occur in organelles and intact cells. Excited triplet states can be enzymatically generated high yields by different routes. An example is the oxidation of isobutanal to acetone formic acid, catalyzed horseradish peroxidase. Other enzymatic systems generate carbonyls are linear aliphatic aldehydes when oxidized peroxidase/O2, or indole-3-acetic acid/peroxidase/O2-reaction. The latter widespread plants. This new field photobiochemistry without light has led a growing awareness idea cells utilize trigger photochemical processes even dark. Such phenomena considerable importance, also for understanding weak photon emission from biological systems.
