  • Title: Limitations of the method using peroxidase activity of hemoglobin for detecting lipid hydroperoxides.
    Author: Shibata SS, Terao J, Matsushita S.
    Journal: Lipids; 1986 Dec; 21(12):792-5. PubMed ID: 3821395.
    Abstract:
    The method using peroxidase activity of hemoglobin (Hb) for the determination of lipid peroxides was examined by using pure methyl linoleate hydroperoxides, trilinoleoylglycerol hydroperoxides and egg yolk phosphatidylcholine hydroperoxides as substrates and tetramethyl benzidine as electron donor for the peroxidase reaction of Hb. The reactivities of these substrates were quite varied. Furthermore, some electron donors were tested for peroxidase activity of Hb, but none showed a complete reduction of methyl linoleate hydroperoxides. From these results, it seems the Hb method needs to be carefully applied to biological materials that contain mixtures of different types of lipid classes.
