Most elements have isotopes, which have the same number of protons but different neutrons. Metabolites are often built from carbon (C), hydrogen (H), oxygen (O), nitrogen (N), sulfur (S) and phosphor (P). In nature, the isotope 13C is present at 1.1% natural abundance. Therefore, ...
The findings of this study, based on experimental and computational analysis, demonstrate that the presence of intercalated molybdenum atoms results in an expansion of the molybdenum disulfide layer spacing and a weakening of the molybdenum-sulfur bonds. Electrochemical properties exhibit diminished ...
Here, we report the production of both siderophore-interacting proteins, the flavin-containing (SbSIP) and iron–sulfur cluster-containing ferric–siderophore reductase (SbFSR) from S. biscestrii. Given the instability of the latter, we only report the structure and biochemical characterization of ...
There is now a wealth of atmospheric composition satellite data for air quality (AQ) applications that has proven valuable to environmental professionals: nitrogen dioxide (NO2), sulfur dioxide (SO2), ammonia (NH3), carbon monoxide (CO), some volatile organic compounds (VOCs), and aerosol optica...
However, the analysis reported here includes more diverse arsC sequences and suggests that other deeply branching types of arsC exist. For example, the arsC sequences from major divisions of Bacteria such as the Green Sulfur Bacteria (represented by Chlorobium tepidum) and the Deinococcales (...
sulfur Class 5 – oxidizing substances; Organic peroxide Oxidants are defined by hazardous materials regulations as substances that may cause or contribute to combustion, usually producing oxygen through redox chemical reactions. Organic peroxides can be considered ...
They provide cells with a large number of metabolites, such as amino acids and steroids, and are involved in the formation of heme and iron-sulfur clusters. Based on proteomic analyses it has been estimated that mitochondria contain ~ 1500 different proteins in mammals and ~ 1000 different ...
Post-translational modifications (PTMs) constitute a major aspect of protein biology, particularly signaling events. Conversely, several different pathophysiological PTMs are hallmarks of oxidative imbalance or inflammatory states and are strongly associ
Vanadium redox cells: A particularly interesting cell uses vanadium oxides of different oxidation states as the anode and cathode. These solutions will not be spoiled if the membrane leaks, since the mixture can be charged as either reducing or oxidizing components....
Twenty substances among the most common allergens are reported. For each one of them, the general characteristics, sources of exposure, clinical presentation, and specific prevention rules are detailed. Special recommandations concerning the percentages
