The element sodium (Na) is highly reactive. Which of the following properties is mainly related to its high reactivity? A. It has a low melting point B. It has one valence electron C. It is a soft metal D. It has a silvery - white color 相关知识点: ...
Also, the Research Triangle Institute (RTI) has presented a reactive adsorption process called the transport reactor naphtha desulfurization (TReND) technology for fuel desulfurization, which is similar to S-Zorb process, but utilizes copper or iron oxide endorsed by Al2O3-ZnO adsorbent at temperatur...
Human alpha globin (4 μM) or hemoglobin A (4 μM) were reacted with sodium nitrite (0.25–4 mM) in the presence of 1 mM sodium dithionite in 0.1 M sodium phosphate buffer, pH 7.4, at 25 °C. Optical spectra were recorded using a Cary 60 spectrophotometer fitted wit...
The dialyzed crude was loaded onto a 5-mL HiTrap SPFF cartridge (GE Healthcare), equilibrated in 10 mM sodium acetate buffer (pH 4) and keeping a flow rate of 1 mL/min. Elution was carried out by applying a linear gradient of 1 M NaCl from 0 to 50% in 25 min. ...
Data obtained suggest that lactone mycotoxins are more highly reactive with simple low-molecular-weight thiols (like GSH) than with complex ones (like Trx). Keywords: patulin (PAT); penicillic acid (PA); aflatoxin B1 (AFB1); maize; thioredoxin (Trx); thioredoxin reductase (Tr); glutathione ...
Intracellular catalase activity instead of glutathione level dominates the resistance of cells to reactive oxygen species. Cell Stres Chaperones 2019, 24, 609–619. [Google Scholar] [CrossRef] [PubMed] Pieńkowska, N.; Bartosz, G.; Pichla, M.; Grzesik-Pietrasiewicz, M.; Gruchala, M.; ...
For example, Mo(CO)6 in aqueous acetonitrile, nickel chloride–sodium borohydride, or SmI2 was used as selective and mild reagent for N–O bond reduction in the presence of functionalities sensitive to other reducing agents (Scheme 38) <1998J(P1)3471, 2001OL1375, 2004TL8375, 2005TL3...
Technical phosphates such as detergent sodium tripolyphosphate (STPP) or phosphates for water treatment, firefighting compositions, and ceramics can be made either from MGA (usual) or via the thermal route. The choice between the two routes is above all cost driven, as a higher quality requires ...
For the precipitation of proteins from cell culture supernatants, serum-free (OptiMEM) conditioned media of the overnight cultures were used. 10 µL (1/100 of vol.) of 2% sodium deoxycholate (NaDOC) was added to 1 mL sample and was shortly vortexed. After 30 min of incubation on ice...
It reflects their composition. Some salts are hydrated - that is, they contain water molecules in their crystal structure (and the water is present there is a more or less constant amount). Some compounds can be easily written as a mixture of oxides, for example sodium metasilicate Na2SiO3can...
