Selected Publications. George P. Lisi, Russell P. Hughes, Dean E. Wilcox, “Coordination Contributions to Protein Stability in Metal-Substituted Carbonic Anhydrase”, Journal of Biological Inorganic Chemistry, 21, Marcelo M. Pedroso, Fernanda Ely, Natasa Mitic, Margaret C. Carpenter, Lawrence R. Gahan, Dean E. Wilcox, James L. Larrabee, David L. . Whey proteins tend to interact with metal ions, which have implications in different fields related to human life quality. There are two impacts of such interactions: they can provide opportunities for applications in food and nutraceuticals, but may lead to analytical challenges related to their study and outcomes for food processing, storage, and food : Agnieszka Rodzik, Paweł Pomastowski, Gulyaim N. Sagandykova, Bogusław Buszewski.

However, the related nickel-interacting proteins have not been fully identified so far. Immobilized-metal affinity chromatography (IMAC) is a separation technique commonly used for fractionating proteins based on their different binding affinities of the surface-exposed amino acids towards immobilized metal ions [19, 20].Cited by: KUMAR & RAI: SPECTROSCOPIC STUDIES OF L-ARGININE MOLECULE Fig. 2 — Raman spectrum of arginine band appears at cm −1 in IR and at cm −1 in Raman spectrum, respectively. There is a good agreement in band positions of IR and Raman spectra. A band appears due to stretching of CC bond at cm −1. Due to stretching of CNH group.

  AbstractThis study describes synthesis, spectroscopic characterization and catalytic activities of Fe(II), Ru(II), Pd(II) and Zn(II) complexes with a novel Schiff base ligand (L) derived from methyl 2-amino-5,5,7,7-tetramethyl-4,5,6,7-tetrahydrobenzo[b]thiophenecarboxylate and terephthalaldehyde. We used spectroscopic techniques including IR, UV-Vis, Cited by: 1. Spectroscopic Determination of Nickel (II) Abstract In this lab, we wanted to determine the concentration of the unknown Ni (II) using a Spectronic 20 D spectrometer and Beer’s Law. The absorbance and the path length of the unknown were measured. The molar absorptivities at certain wavelength were determined by drawing the absorbances-concentration graph of four .

The electronic absorption spectra of the complexes M(L)Cl2 and M(L)2Cl2 [M=NiII or PdII; L=thiosemicarbazide (tsc), 1-phenylthiosemicarbazide (1-phtsc), or 4-phenylthiosemicarbazide (4-phtsc)] were investigated in a number of solvents.

The complexes Ni(tsc)Cl2, Ni(tsc)2Cl2, Ni(4-phtsc)Cl2 and Ni(4-phtsc)2Cl2 exist in a distorted Oh geometry Cited by: 2. Nickel(II) complexes of the general composition Ni(L)X 2 (where X = SCN, NO 3 and 1/2SO 4 and ligands = L 1 L 2 and L 3) have been synthesized and characterized by elemental analyses, magnetic moments, IR, 1 H NMR, 13 C NMR and electronic spectral studies.

Nickel(II) ions, such as nitrates, thiocyantes and sulphates were found to act as templates for the cyclic Cited by: The single crystal X-ray diffraction studies show square planar geometry around Ni(II) in all three complexes, and conform to the results obtained by spectroscopic studies.

The electrochemical investigation of these complexes at a carbon paste electrode in water solution indicates that the Ni(II/III) oxidation process was by: Proteins are assembled from amino acids using information encoded in genes. Each protein has its own unique amino acid sequence that is specified by the nucleotide sequence of the gene encoding this protein.

The genetic code is a set of three-nucleotide sets called codons and each three-nucleotide combination designates an amino acid, for example AUG. Metalloprotein is a generic term for a protein that contains a metal ion cofactor.

A large proportion of all proteins are part of this category. For instance, at least human proteins (out of ~20,) contain zinc-binding protein domains although there may be up to human zinc metalloproteins.

The spectral studies suggested octahedral geometry for the Co(II), Ni(II), and Zn(II) complexes and square planar for Cu(II) complexes (Figure 6). No signal at half.ADVERTISEMENTS: Some of the important types of Spectroscopic Techniques are as follows: Type # 1.

Gamma Spectroscopy: Gamma spectroscopy is a radionuclide measurement method. While a Geiger counter determines only the count rate, a gamma spectrometer will determine the energy and the count rate of gamma-rays emitted by radioactive substances.
