Metmyoglobin (MetMb), H2O2-activated by glucose-oxidase/glucose system, initiated membranal lipid peroxidation. No such peroxidation occurred in the presence of the glucose oxidase system, H2O2, or MetMb alone. Heated MetMb maintained its capacity to be activated by H2O2. The accumulation of thiobarbituric reactive substances (TBA-RS) and oxygen absorption showed a higher rate of lipid peroxidation by H2O2-activated MetMb in microsomes separated from turkey than from chicken muscle tissues. Membranal lipid peroxidation initiated by activated MetMb was inhibited by low concentrations of either ascorbyl palmitate, α-tocopherol, or butylated hydroxytoluene (BHT). Inhibition was also observed by very low concentrations of ascorbic acid in the presence of EDTA. Only very high concentration of EDTA (1–10 mM) inhibited significantly membranal lipid peroxidation by activated metmyoglobin. © 1985, American Chemical Society. All rights reserved.
