Measurement of lipid hydroperoxides by the ferric-xylenol orange method (1) characteristics of the ferric-xylenol orange/membrane phosphatidylcholine complex.
The ferric-xylenol orange (FOX) method for measurement of hydroperoxides is based on a technique that employs reduction of peroxides in an acidic condition by Fe2+ and formation of the colored ferric-xylenol orange (XO/Fe3+) product with a peak at 560 nm. The 560 nm absorbance peak of XO/Fe3+ shifts to a 610 nm peak with high absorption intensity in the presence of phosphatidylcholine. This is ...
متن کاملDetermination of hydroperoxides in aqueous solutions containing surfactants by the ferrous oxidation-xylenol orange method.
Some surfactants widely used as additives in food, pharmaceuticals, and cosmetic formulations are susceptible to peroxidation resulting in accumulation of hydroperoxides (HP). Our investigation was aimed to study the possible influence of different surfactants on the proportionality and reproducibility of the ferrous oxidation-xylenol orange method developed originally for the determination of ...
متن کاملSolid Phase Spectrophotometric Determination Of Cobalt By Xylenol Orange
A simple and sensitive solid phase spectrophotometric method for the determination of cobalt is proposed based on the reaction between cobalt and xylenol orange (XO). The reaction product is fixed on the anionic exchanger resin sephadex QAE A-25 at pH= 5. The optical absorbance of the anionic gel like resin, packed in a 1.00 mm cell is directly measured at 588.0 nm. The linear range of calibrat...
متن کاملA Highly Sensitive Method for Quantitative Determination of L-Amino Acid Oxidase Activity Based on the Visualization of Ferric-Xylenol Orange Formation
L-amino acid oxidase (LAAO) has important biological roles in many organisms, thus attracting great attention from researchers to establish its detection methods. In this study, a new quantitative in-gel determination of LAAO activity based on ferric-xylenol orange (Fe(III)XO) formation was established. This method showed that due to the conversion of Fe(II) to Fe(III) by H2O2 and subsequent fo...
