Tilapia (Oreochromis niloticus) protein was hydrolysed by papain, and then the tilapia (Oreochromis niloticus) protein hydrolysates (TPH) chelated with ferrous ions at various mass ratios of TPH to FeCl2 (5:1, 10:1 and 20:1) to obtain the biological materials of chelate I, chelate II and chelate III, respectively. The ferrous-binding rate and antioxidant activities of the chelates were investigated. It was found that the ferrous-binding rate increased with the increase of mass ratios (TPH/FeCl2) from 5:1 to 20:1. The DPPH radical scavenging activity and reducing power activity of chelate III w

Traditionally, trace elements are supplemented in the diet of the animals as inorganic salts. However, recently there are many reports indicating that absorption and utilization of trace elements is comparatively far better if they are supplemented in the chelated forms related to their inorganic salts. A large number of studies conducted on chelated forms of trace elements indicate that they not only improve the performance of the animals in respect of growth, milk production, wool production or reproduction but they are effective in reducing the various stresses and also improve the immune r

The element iron plays a key role in plant physiology. For plant nutrition, chelated forms of iron are preferred. Therefore, in clonal micropropagation media, FeSO4 x 7H2O is usually introduced together with Na2EDTA. At the same time, other effective iron chelates with both carboxyl and phosphorus chelates are known. So far, there are few scientific studies on the effect of iron chelates complexes on blueberry plants under in vitro conditions. Therefore, studies were conducted with different iron chelate complexes in 4 concentrations on highbush blueberry (Vaccinium corymbosum L.) cv. Brigitta

Thrombin is a trypsin-like serine protease that plays a critical role in the blood coagulation cascade. Thus, studies on thrombin-specific inhibitor are useful for the design of clinical useful compounds. We have previously reported of the Schiff base metal chelates carrying benzamidine and amino acid moieties. More than 50 kinds of Schiff base copper(II) chelates were synthesized fromp- orm-amidinosalicylaldehyde and various L- or D-amino acids. These chelates have effective inhibitory activity for trypsin and thrombin (Ki= 10-5~ 10-6M). In this series of inhibitors, the copper(II) chelate de

In addition, all chelates were tested against bacterial strains and the HepG2 cell line to determine their antiseptic and carcinogenic properties. The Ni(II) complex was preferable to the other chelates. Molecular optimization revealed that H2L had the highest reactivity, followed by Hg-chelate, Ag-chelate, Ni-chelate, and Cu-chelate. Moreover

Abstract In this paper, the toxic effect of a complex chelate mixture containing microelements (Fe, Mn, Zn, Se, I, Cu) on Danio rerio was investigated. Chelated compounds are used to detoxify elements in the aquatic environment, as well as feed additives for various types of farm animals. The effect of chelate complexes was studied according to the following parameters: LC50, survival in chronic experience (30 days), embryotoxicity and genotoxicity by the micronucleus test method. The established LC50 value was 2.73 mg/l, the maximum allowable concentration that does not have a negative effect

The coupling of diazotized 1-aminonaphthalene with 1,3-dicarbonyl compounds (acetylacetone, methylacetoacetate and acetoacetanilide) yielded a new series of bidentate ligand systems (HL). Analytical, IR, 1H-NMR and mass spectral data indicate that the compounds exist in the intramolecularly hydrogen bonded keto-hydrazone form. With Ni(II), Cu(II) and Zn(II), these potential monobasic bidentate ligands formed [ML2] type complexes. The IR, 1H- -NMR and mass spectral data of the complexes are consistent with the replacement of the chelated hydrazone proton of the ligand by a metal ion, thus leadi

However, the dependence of the reaction rate on the concentration of chelate in solution has never been quantified.

Resumo:
Rhizoferrin, a siderophore produced by Rhizopus arrhizus, has been shown in previous studies to be an outstanding Fe carrier to plants. However, calculations based on stability constants and thermodynamic equilibrium lead to contradicting conclusions. In this study a kinetic approach was employed to elucidate this apparent contradiction and to determine the behavior of rhizoferrin under conditions representing soil and nutrient solutions. Stability of Fe3+ complexes in nutrient solution, rate of metal exchange with Ca, and rate of Fe extraction by the free ligand were monitored for rhizoferrin
