“…These two compounds provide the spectrophotometric properties, as they form complexes with the ferric ion, giving maximum absorbance peaks at 500 nm and 560 nm respectively, which can be measured with a UV-Vis Spectrophotometer [6,[14][15][16][17][18]. However, neither of the methods is free from complications [19].…”

Lipid oxidation analysis in food samples is a relevant topic since compounds generated in the process are related to undesirable sensory and biological effects. As the process is complex and depends on the type of lipid substrate, oxidation agents and environmental factors, proper measurement of lipid oxidation remains a challenging task. A great variety of methodologies have been developed and implemented so far, both for determining primary oxidation products and secondary oxidation products. Most common methods and classical procedures are described, including peroxide value, TBARS analysis and chromatography. Some other methodologies such as chemiluminescence, fluorescence emission, Raman spectroscopy, infrared spectroscopy or magnetic resonance, provide interesting and promising results, so attention must be paid to these alternative techniques in the area of food lipid oxidation analysis.

“…Similarly, thiobarbituric acid reactive substances (TBARS), lipid hydroperoxide (LOOH) and protein carbonyls were measured in homogenates as described previously [27][28][29]. Homogenate protein content was measured using the Bradford method (Bio-Rad Laboratories, Regents Park, NSW, Australia).…”

Aims/hypothesis Metabolic disorders are commonly investigated using knockout and transgenic mouse models. A variety of mouse strains have been used for this purpose. However, mouse strains can differ in their inherent propensities to develop metabolic disease, which may affect the experimental outcomes of metabolic studies. We have investigated straindependent differences in the susceptibility to diet-induced obesity and insulin resistance in five commonly used inbred mouse strains (C57BL/6J, 129X1/SvJ, BALB/c, DBA/2 and FVB/N). Methods Mice were fed either a low-fat or a high-fat diet (HFD) for 8 weeks. Whole-body energy expenditure and body composition were then determined. Tissues were used to measure markers of mitochondrial metabolism, inflammation, oxidative stress and lipid accumulation. Results BL6, 129X1, DBA/2 and FVB/N mice were all susceptible to varying degrees to HFD-induced obesity, glucose intolerance and insulin resistance, but BALB/c mice exhibited some protection from these detrimental effects. This protection could not be explained by differences in mitochondrial metabolism or oxidative stress in liver or muscle, or inflammation in adipose tissue. Interestingly, in contrast with the other strains, BALB/c mice did not accumulate excess lipid (triacylglycerols and diacylglycerols) in the liver; this is potentially related to lower fatty acid uptake rather than differences in lipogenesis or lipid oxidation. Conclusions/interpretation Collectively, our findings indicate that most mouse strains develop metabolic defects on an HFD. However, there are inherent differences between strains, and thus the genetic background needs to be considered carefully in metabolic studies. Keywords

“…The principle of the FOX method is based on the oxidation of ferrous ions to ferric by the hydroperoxide activity in the acidic environment [90][91][92][93][94]. The exact mechanism of the sequence of radical reactions is not known, but the mechanism has been designed by Gupta et al [95] and is shown in reactions 1-4 (equation 2) [96].…”
