Participation of Chelating Metals in Carboxylation Reactions
نویسنده
چکیده
Introduction Chelate compounds, arising out of the combination of inorganic ions with polyfunctional organic molecules, may be expected to hold great interest for investigators in widely different fields of chemistry. The stability of many such substances can be an important factor both in the manipulation of ionic equilibria and in the alteration of organic structures. In the former application there has been great progress in recent years, so that the use of polyfunctional organic compounds as precipitants, titrants, and solubilizing agents for metals is now common. Alteration of the effective emf of a redox system such as represented in EQUATION 1, by addition of a chelating agent that will preferentially bind one of the metal ions (EQUATION 2), is likewise familiar.

ABSTRACT: Oxidation might be regarded as one of the most important reaction in oils and fats. Prooxidants namely iron and copper intensify and catalyze the oxidation while the chelating agents might retard or delay this process. Citric acid, phosphoric acid, some of phenolic compounds and phospholipids are considered as the compounds that chelate the prooxidant metals and through this mechanism...

A previous study in this laboratory (12) indicated that leaves and excised roots of bush beans grown under conditions of Fe deficiency fixed larger quantities of C1402 from an enriched atmosphere than did those receiving adequate amounts of Fe. For this reason, studies have been made to determine the effect of Fe and chelating agents on PEP (phosphoenolpyruvate) carboxylase (1, 9, 13), PEP carb...

Peptides are one of the best candidates for drug development due to their high specificity and low toxicity and porphyrins are significant macromolecules in biological systems with important roles. In this works ynthesis of dipeptide (histidine-β-alanine) was done by solid-phase peptide synthesis method (SPPS) and tetrakis(4-sulfonatophenyl)porphyrin (TPPS4) was synthesized by Adler method. The...

The cleaning and shaping of root canals is one of the most important proccesses in endodontics. In many cases, the physiologic or pathologic proccedures can affect the canals. So, using the instruments and materials, which could be applied in cleaning and shaping of narrow canals is necessary. The aim of this study was the evaluation of Iranian and foreign chelating agents on periradicular tiss...
