To determine the absolute amount of lipid hydroperoxides in biological materials, a simple and sensitive colorimetric method was newly developed, based on the reaction of lipid hydroperoxides with a leucomethylene blue derivative in the presence of hemoglobin. The amount of methylene blue formed was measured by its absorbance at 666 nm to calculate the amount of lipid hydroperoxides using cumene hydroperoxide as external standard. By this method, lipid hydroperoxide concentrations of less than 7.5 nmol/tube were accurately determined.

UI MeSH Term Description Entries
D008054 Lipid Peroxides Peroxides produced in the presence of a free radical by the oxidation of unsaturated fatty acids in the cell in the presence of molecular oxygen. The formation of lipid peroxides results in the destruction of the original lipid leading to the loss of integrity of the membranes. They therefore cause a variety of toxic effects in vivo and their formation is considered a pathological process in biological systems. Their formation can be inhibited by antioxidants, such as vitamin E, structural separation or low oxygen tension.

D008751 Methylene Blue A compound consisting of dark green crystals or crystalline powder, having a bronze-like luster. Solutions in water or alcohol have a deep blue color. Methylene blue is used as a bacteriologic stain and as an indicator. It inhibits GUANYLATE CYCLASE, and has been used to treat cyanide poisoning and to lower levels of METHEMOGLOBIN.
