In an effort to elucidate the mechanism of the initiation reaction of the denaturation of oxyhemoglobin, I, to methemoglobin, II, by hydrazines, we have investigated by electron paramagnetic resonance, EPR, and visible spectrophotometry at 22 degrees C, pH 7.4, the
The surface reaction between manganese dioxide and 1, 1-diphenyl-2-picrylhydrazine. Two type EPR methods for the estimation of active surface areas of oxides.
Inhibition of α-amylase and α-glucosidase, advanced glycation end products (AGEs) formation, and oxidative stress by isolated active constituents of Osmanthus fragrans flowers (9,12-octadecadienoic acid and 4-(2,6,6-trimethyl-1-cyclohexenyl)-3-buten-2-one) and their structural analogues were evaluated. 9,12-Octadecadienoic acid was 10.02 and 22.21 times more
Peanut protein isolate (PPI) was hydrolysed with alcalase to obtain antioxidant peptides. To purify these peptides, the peanut protein isolate hydrolysates (PPIH) were separated by ultrafiltration (MWCO=3kDa) and the obtained PPIH-II (Mw<3kDa) with higher antioxidant activity was further separated by
Composition of fatty acids, tocopherols, tocotrienols, and carotenoids, and their contribution to antioxidant activities were investigated in seeds of three coloured quinoa cultivars (white, red and black). The major components and individual compounds were significantly different, and their concentrations were
