Correlation of membrane lipid peroxidation with oxidation of hemoglobin variants: possibly related to the rates of hemin release.

Abstract excerpt

Experiments were performed to delineate the biochemical mechanism of hemoglobin (Hb)-catalyzed lipid peroxidation in human red blood cells (RBCs). Using a modified Langmuir trough lipid monolayer technique, we found that oxidized Hb induced an increase in lipid monolayer surface pressure, suggesting that oxidized Hb readily releases its heme moiety into the lipid monolayer. To confirm our interpretation that...
