Tryptophan synthase alpha 2 beta 2 complex containing [4'-3H]pyridoxal phosphate was reduced with sodium borohydride in the presence of various substrates and analogs in an attempt to trap reaction intermediates. Reduction in the presence of L-serine gave noncovalently bound radioactive material which was identified as phosphopyridoxylalanine, presumably resulting from reduction of the intermed...

A nanocomposite of silver nanoparticles and reduced graphene oxide (Ag/rGO) has been developed as a catalyst for the reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP) with sodium borohydride, owing to the larger specific surface area and synergistic effect of rGO. A facile and rapid microwave-assisted green route has been used for the uniform deposition of Ag nanoparticles and the reduc...

In this communication, we present the crystal structure of a secondary amine: 4-chloro-N-(1-(pyridin-2-yl)ethyl)aniline (Lb) obtained from stepwise reduction an imine, (E)-N-(4-chlorophenyl)-1-(pyridin-2-yl)ethan-1-imine (La) with sodium borohydride. The was characterized by FT-IR, 1H and 13C NMR, Mass Spectroscopy X-ray diffraction.

Surface oxidized carbon vulcane XC-72 is prepared as catalyst support and platinumnanoparticles are chemically anchored onto the modified surface. The nanoparticles of Pt weresynthesized by reduction of H2PtCl6 with sodium borohydride in a 5.5 M buffer solution ofsodium citrate; the complexation of citrate with metal ions is beneficial to the formation ofnanoparticles. The electro-oxidation of ...

well faceted cuo nanoparticles, were synthesized by thermal-assisted dissociation method at reflux temperature in a short period of time. a possible mechanism for synthesis of such highly pure and stable nanoparticles is tentatively proposed by ft-ir study. the large surface area and rich exposed active sites are expected to endow such nanoparticles with excellent performances in catalysis as d...

We have developed a colorimetric assay for determining the degree of glycation of serum proteins that is unaffected by glycosylation residues. This was accomplished by reducing the proteins with sodium borohydride prior to periodate oxidation. Previous periodate-based methods, which offer several advantages over other glycation assays, cannot determine glycoprotein glycation because interferenc...

the hydrolysis of sodium borohydride as a source of hydrogen gas is studied at different mole ratios of h+ to nabh4. the sulfonated porous carbon (spc) is used as a source of hydrogen ion and catalyst. it is found that the sulfonated porous carbon exhibits high activity for the hydrolysis of nabh4 to generate hydrogen gas at room temperature in comparison to amberlyst-15 and nafion-nr50. the ki...
