13. Study of complexes of cadmium with some L-amino acids and vitamin-C by voltammetric technique
Voltammetric technique was used to study the binary and ternary complexes of cadmium with L-amino acids and vitamin-C (L-ascorbic acid) at pH =7.30 ± 0.01, µ = 1.0M KNO3 at 25ºC and 35ºC. Cd (II) formed 1:1:1, 1:1:2 and 1:2:1 complexes with L-lysine, L-ornithine, L-threonine, L-serine, L-phenylglycine, L-phenylalanine, L-glutamic acid and L-aspartic acid

15. Estudo do equilibrio de fases e de estruturas de complexos formados entre polietilenoiminas e dodecilsulfato / Phase equilibria and structural study of polyethyilenoimine and dodecylsulfate complexes
Polyelectrolytes associate strongly with oppositely charged surfactants in water, being able to generate liquid crystalline phases with interesting supramolecular structures. The geometry of the liquid crystalline phase depends on parameters such as: concentration, surfactant/monomer ratio, polymer characteristics and presence of cosolvents. The objective of

17. STUDY OF TERNARY COMPLEXES OF CO(II) AND NI(II) WITH THE AMINO ACIDS GLYCINE, SERINE, ASPARTIC ACID AND GUANIDINOACETIC ACID, IN SOLUTION / ESTUDO DE COMPLEXOS TERNÁRIOS DE CO(II) E NI(II) COM OS AMINOÁCIDOS GLICINA, SERINA, ÁCIDO ASPÁRTICO E ÁCIDO GUANIDOACÉTICO, EM SOLUÇÃO
Foram estudados os sistemas binários e ternários de cobalto (II) e de níquel(II) com os aminoácidos glicina, serina, ácido aspártico e ácido guanidoacético. Os aminoácidos glicina - Gly, serina - Ser, ácido aspártico - Asp e ácido guanidoacético - Gaa estão envolvidos em muitos processos bioquímicos. Esses aminoácidos fazem parte de muitas pr

20. Construção e análise de mutantes fluorescentes da troponina I / Construction and analysis of fluorescent mutants of troponin I
Vertebrate striated muscle contraction is regulated by troponin (Tn). Tn is composed of three subunits: troponin I (TnI), troponin C (TnC) and troponin T (TnT). TnI has an inhibitory role that is neutralized by calcium binding to the regulatory sites in the N-domain of TnC, and TnT positions the troponin complex on the thin filament. In order to follow the C

21. Estudos de adsorção e equilíbrio nos sistemas Cd(II) / SCN-/ C6H12N4 e Cd(II)/I-/SCN-. aperfeiçoamento de métodos e eletrodo / Adsorption and equilibrium studies of the systems Cd(II)/SCN-/C6N12H14 and Cd(II)/I-/SCN-. Improvement of methods and of the electrode
Na presente tese investigou-se a adsorção induzida de um cátion metálico (cádmio(II)) na presença simultânea de dois ligantes (um pseudo-haleto e uma amina ou haleto) na interface eletrodo de mercúrio/solução aquosa, com vistas a uma melhor compreensão desse processo. Os estudos de adsorção foram precedidos por estudos de equilíbrio dos compost

22. Emprego de acidos hidroxamicos na extração dos ions Co (II), Cu (II), Fe (III), Ti (IV) e V(V) por solventes organicos e sua determinação por espectrofotometria de absorção atomica e na região do UV - visivel
For this project four hydroxamic acids were synthesized, two being derivatives of phenylcinnamohydroxamic acid and two of phenylbenzohydroxalllic acid. N-benzoyl-p-tolylhydroxylamine was used for the extraction and separation of Copper (lI) and Iron (lII) in toluene, in the pH ranges of 7.0 to 10.0 and 1.0 to 6.0, respectively. The copper extracted with this

23. Binding Thermodynamics of Ferredoxin:NADP+ Reductase: Two Different Protein Substrates and One Energetics
The thermodynamics of the formation of binary and ternary complexes between Anabaena PCC 7119 FNR and its substrates, NADP+ and Fd, or Fld, has been studied by ITC. Despite structural dissimilarities, the main difference between Fd and Fld binding to FNR relates to hydrophobicity, reflected in different binding heat capacity and number of water molecules rel

24. A prokaryotic-like mode of cytoplasmic eukaryotic ribosome binding to the initiation codon during internal translation initation of hepatitis C and classical swine fever virus RNAs
Initiation of translation of hepatitis C virus and classical swine fever virus mRNAs results from internal ribosomal entry. We reconstituted internal ribosomal entry in vitro from purified translation components and monitored assembly of 48S ribosomal preinitiation complexes by toe-printing. Ribosomal subunits (40S) formed stable binary complexes on both mRN
