The presence of S degrees-containing impurities in commercial samples of oxidized glutathione and their catalytic effect on the reduction of cytochrome c.

چکیده
The stimulatory effect of GSSG on the reduction of cytochrome c by GSH has been shown to be due to SO-containing impurities; GSSG itself has no stimulatory effect. Methods are described for the production of such impurities in high yield. Similar effects are shown by cystine trisulfide. The stimulation of the cytochrome c reduction rate has been found to be catalytic; one molecule of cystine trisulfide will induce the rapid reduction of at least 25 molecules of cytochrome c.

We have investigated the effect of theophylline on the kinetics of the catalytic subunit of protein kinase and related factors in lung tissue. The results show that the point of highest concentration of the C subunit of protein kinase which is active in casein phosphorylation is at 3h of incubation time, but in the presence of 100 Ilg/ InL and 10µg/mL theophylline, this is shifted to I.S an...
متن کاملCatalytic Kinetic Determination of Silver through its Catalytic Effect on Congo Red-Peroxodisulphate Reaction
A kinetic-spectrophotometric procedure is reported for determination of trace amounts of Ag(I). This method is based on catalytic effect of silver ion on the oxidation of congo red by potassium peroxodisulphate at pH=3.4 and 30 oC in the presence of 1,10-phenanthroline as an activator. The reaction was followed spectrophotometrically by measuring the rate of change in absorbance ...

Biotransformation of benzo[a]pyrene (BaP) in the presence of microsomal fractions derived from liver and epiderm of adult and weanling rats was examined. The aim of this study was to evaluate the effect of age on the capacity of two organs in transformation of BaP. Subcellular fractions were prepared from skin and liver by ultracentrifugation and were used as the source of BaP metabolizing enzy...

The effect of SiC content, additives, and process parameters on densification and microstructural properties of pressureless sintered ZrB2– (1–10 wt %) SiC particulate composites have been studied. The ZrB2–SiC composite powders mixed by Spex mixer with 1-2wt% C (added as graphite powder) and CMC have been cold-compacted and sintered in argon environment in the temperature range of 1800–2100ºC ...
متن کاملHigh Performance Liquid Chromatography Coupled with Pre-column Derivatization for Determination of Oxidized Glutathione Level in Rats Exposed to Paraquat
Glutathione (GSH) is one of the most important antioxidants that plays an essential role in detoxification of reactive oxygen species (ROS) which oxidizes to glutathione disulfide (GSSG). Paraquat (PQ), awidely used herbicide, causes pulmonary injury with the productionof ROS. Excessive ROS accumulation as a consequence of PQ exposure are frequently targeted by GSH thereby oxidative stress lead...
