Thermodynamic-Biochemical Study of Complexes of Intermediate Elements with α-Amino Acids in Some Proteins with Active Site
In this paper, the quantum chemistry calculations related to the structural parameter of the chromite and molybdate anions and the complexes obtained from them with the glycine and alanine amino acids were performed. The calculations were carried out using HF and DFT methods and in the base series 6-31G *. Thermodynamic studies related to the formation of complexes have been considered and thei...
متن کاملCatalytic Effects of Carbon Nanotubes on Complexation of Some Amino Acids via Cobalt Cation Catalyst
In this research, investigation of the adsorption isotherms and the effect of solution conditions such as pH and concentration of complexation of some amino acids with cobalt(II) nitrate six-hydrate upon multi-wall type carbon nanotube (CNT) were done. The adsorption capacity of complexation of amino acids onto the surface of carbon nanotube increased with the pH from acidic to alkaline. At pH ...
متن کاملA STUDY OF ULTRASONIC ABSORPTION OF SOME AMINO ACIDS AND THEIR MIXTURES AT PHYSIOLOGICAL pH
In this paper, the ultrasonic absorption of amino acids was measured using a small cylindrical resonator at physiological pH and 25°C and a concentration of 0.1. M. The absorption of mixtures of some amino acids was also measured. In the case of cysteine-histidine, the absorption of mixtures is much larger (more than twice) than the summation of absorption of the individual amino acid. This...
متن کاملApplication of the Freundlich Langmuir Temkin and Harkins-Jura adsorption isotherms for some amino acids and amino acids complexation with manganese kn(ll) on carbon nanolube
In lb is research, adsorption of some amino acids and their complenation with manganese (II) ion on carbonnanotube (MWCNT) by using of four relations Langmuir, Freundlich. Temkin and Harkins -Jura imitherms wasinvestigated. From this relations. Freudlich and Temkin relations predict good equilibrium diagram in, isothermcondition. we could compute the theoretical constants by excel software. Hy ...
متن کاملSynthesis and characterization of dibutyltin compounds with α-amino acids
This study describes the preparation and description of four new complexes: Bu2Sn(AA)Cl (AA = glycine, DL = valine and L = leucine) and Bu2SnPhen2 (Phen = DL-phenylalanine). They were characterized by elemental analyses for carbon, hydrogen, nitrogen, chlorine and tin by infrared, 119mSn-Mössbauer and 119mSnRMN spectroscopies and by the applications of TG and DSC techniques in a dynamic helium ...
