Abstract: The presence of enzymically generated triplet acetone in red cells and energy transfer to eosin, rose bengal and 9,10-dibromoanthracene-2-sulfonate was indicate by: (1) product distribution; (2) KET τo, similar to the 2-methylpropanal/peroxidase/O2 system; (3) correlation between hemolysis, oxygen uptake and photon emission; (4) membrane protection by energy acceptors, and (5) by comparison of the 2-methylpropanal/peroxidase/O2 system with 2-methylpropanal/red cells/membranes/O2 and 2-methylpropanal/acid extractable protein from red cells membrane/O2 systems, which have a high peroxidase activity. This is the first report of a biological system producing a photohemolysis effect in the dark. © 1979.
