Synthesis, X-ray crystallography, spectroscopic characterization and spectroscopic/electrochemical evidence of formation of phenoxy free radical in active center analogs of galactose oxidase – [Cu(Salgly)H2O] and [Cu(Salphenylalanine)H2O]

Autor: Biva Das, Okhil K. Medhi

Publikováno v: Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy. 104:352-357

The formation of phenolate free radical is the factor of high turnover for catalytic activity of galactose oxidase (GO) compared to that by inorganic complexes. A new active center analog of GO, [Cu(II)(Salphenylalanine)H2O] have been synthesized and

Green Synthesis Of Gold Nanoparticles Using Camellia Sinensis And Kinetics Of The Reaction

Autor: Chitrani Medhi, Konwar Boruah, Pradyut Sarma, Okhil K. Medhi, Prabin Kumar Boruah

Publikováno v: Advanced Materials Letters. 3:481-486

In this paper we report the green synthesis of gold nanoparticles (AuNPs) by using a simple, faster, low cost, eco-friendly technique. The green synthesis of AuNPs was done by using fresh young leaves and leaf buds of tea (Camellia Sinensis). Reducti

Synthesis, structure and properties of cetyltrimethylammonium polyiodides

Autor: Babulal Das, Okhil K. Medhi, Neelotpal Sen Sarma, Ganesh Chandra Das

Publikováno v: Polyhedron. 37:14-20

A series of compounds of the cetyltrimethylammonium cation with polyiodides were synthesized and the crystal structures were determined by single crystal X-ray diffraction. The newly synthesized compounds C16H33N(CH3)3I3 and C16H33N(CH3)3I5 exist as

Interaction of small aromatic molecules: An ab initio studies on benzene and pyridine molecules

Autor: P. Hazarika, A. Gogoi, Bipul Bezbaruah, Okhil K. Medhi, Chitrani Medhi

Publikováno v: Journal of Biophysical Chemistry. :32-36

The use of appropriate level of theories for studying weak interactions such as stacking of aromatic molecules has been an important aspect, since the high level methods have limitations for application to large molecules. The differences in the stac

Effect of surfactant and pH on the redox potential of microperoxidase 11 in aqueous micellar solutions

Autor: Okhil K. Medhi, Diganta Kumar Das

Publikováno v: Journal of the Chemical Society, Dalton Transactions. :1693-1698

The redox potential of heme undecapeptide from cytochrome c (microperoxidase 11) in aqueous sodium dodecyl sulfate (sds), hexadecyltrimethylammonium bromide, and Triton X-100 surfactant micelles varied from +2 mV at pH 3.0 to –222 mV at pH 9.0. The

Stability and characterization of iron(III) and iron(II) heme peptides encapsulated in aqueous detergent micelles: proton NMR and UV-visible spectroscopic studies

Autor: Samaresh Mitra, Shyamalava Mazumdar, Okhil K. Medhi

Publikováno v: Inorganic Chemistry. 30:700-705

Proton NMR and optical spectral studies on a heme undecapeptide in aqueous SDS micelles at different pHs are reported. In a micellar solution the monodispersed heme peptide is found to be encapsulated inside the hydrophobic micellar cavity. pH depend
