Metal Ion Complexes of p-Toluenesulfonyl Amino Acids
ثبت نشده
چکیده
The methods of polarographic analysis have been applied to the study of dilute aqueous solutions of various divalent transition metal cations coordinated to p-toluenesulfonyl glycine. Metal cations used were cadmium (II), copper (II), lead (II), mercury (II), manganese (II) and zinc (II). Six new and previously unreported compounds were prepared and studied polarographically, and their dissociation constants and coordination numbers are herein reported. Free energies of formations are also given for several of the complexes. In general, these data agree with similar data in the literature for the complexes of glycine itself.

Metal-Ion-Coordinating Properties of Various Amino Acids, Investigation of the Essential Function in Biological Systems regarding to their Nano-Structure
The acidity constants of some amino acids (Am) were determined by potentiometric pH titration. The stability constants of the 1:1 complexes formed between M2+: Ca2+, Mg2+, Mn2+, Co2+, Ni2+, Cu2+ or Zn2+ and Am2-, were determined by potentiometric pH titration in aqueous solution (I = 0.1 M, NaNO3, 25°C). The order of the stability constants was reported. It is shown that the stability of the bi...

متن کاملIdentification of Amino Acids Involve in Indium Binding To Serum Human Apo-Transferrin
Indium is a heavy metal belonging to group IIIa. It is used as a radioimaging and chemotherapeutic agent in diagnosis and also in the treatment of cancers. It is believed that indium may interfere with iron metabolism and reduce cell growth in cancer tissue. The present report was established to study the binding of iron and indium to apo-transferrin (apo-tf) and to identify amino acids involv...
متن کاملFlavin‐Based Light‐Driven Fluorescent Probe for the Detection of Antioxidant Amino Acids
We have synthesized a flavin-N(5)-oxide derivative with a p-toluenesulfonyl (Ts-OF) group as a "turn-on" fluorescent probe for the detection of several antioxidant amino acids and biothiols. Oxidized flavin was synthesized by using dithiothreitol as the reducing agent. Ts-OF showed a light-driven fluorescence enhancement in the presence of several amino acids and biothiols such as histidine (Hi...
