The Interaction of Chaotropic Anions with Acid Ferricytochrome c

The interaction of chaotropic anions with acid ferricytochrome c.

The influence of the sodium salts of various anions on the spectral properties of acid ferricytochrome c was investigated. It was found that chaotropic anions convert the high spin form of the enzyme into a mixed spin spectral type. The following order of efficiency was established: TBA> TCA> C104> SCN> NO3> Br> Cl(where TBAand TCArepresent tribromoacetate and trichloroacetate ions, respectivel...

study of dna interaction with ethylenediaminetetraacetic acid and sesamol food additives

برهمکنش dnaتیموس گاوی طبیعی (ct-dna) با اتیلن دی آمین تترااستات (edta)در بافرtris-hcl با 8/7 ph ( دراین ph،edta به نمک دی سدیم تبدیل می شود) وسسامول در بافر tris-hcl با4/7 ph مورد بررسی قرار گرفته است. edta و سسامول استفاده فراوانی در تکنولوژی غذایی و صنعت شیمیایی دارند. مدل اتصال dna مربوط بهedta بوسیله اسپکتروفتومتری جذب، دورنگ نمایی حلقوی(cd)، ویسکومتری وژل الکتروفورز بررسی شده است. طیفuv ...

Computational studies on the interaction of vitamin C (ascorbic acid) with nitrogen modified TiO2 anatase nanoparticles

Density functional theory calculations were performed to investigate vitamin C interaction withN-doped TiO2 anatase nanoparticles. The adsorption of vitamin C on the energy favorable fivefoldcoordinated titanium sites was investigated. Various adsorption geometries of vitamin C towardsthe nanoparticle were examined. Since the adsorption energies of N-doped nanoparticles are higherthan those of ...

Reaction between hydrocyanic acid, cyanide ion and ferricytochrome c.

The reactivity of ferricytochrome c with ionic ligands.

where L is ligand and Pr is the protein liberated by the incoming ligand. With ferricytochrome c, the [Hf] dependence of the equilibrium constant for complex formation is determined by the ionization equilibrium of the ligand species HL = H+ + L-, the coordinated water molecule -Fe+-HZ0 G FeOH + H+, and the nitrogenous base group which is liberrated -XH+ = X + Hf. Studies of the equilibrium con...
