Fulvic Acids and Viral Infections
Fulvic acids are active principles in humic substances allowing big absorption of mineral ions from soil through vegetables. They are formed by large organic molecules having several reactive sites. Tested in mice and rats with radioactive labeled ions (Ca, PO4, Fe and I) in drinking water, it has been found that for even concentrations of mineral ions (μg/ml), more than double of them are filt...

متن کاملInteraction of anions and divalent metal ions with phosphoenolpyruvate carboxykinase.
The catalytic activity of phosphoenolpyruvate carboxykinase in rat liver cytosol is stimulated by incubating with Fe2+, Mn2+, Co2+, and Cd2+. When purified, the enzyme no longer responds to Fe2+, Co2+, or Cd2+ but retains a response to Mn2+. Low concentrations of SO4(2-) in the incubation medium with enzyme and divalent transition metal allow stimulation by Fe2+ and Co2+ and enhance the respons...
متن کاملInteraction and conformational changes of chromatin with divalent ions.
We have investigated the interaction of divalent ions with chromatin towards a closer understanding of the role of metal ions in the cell nucleus. The first row transition metal ion chlorides MnCl2, CoCl2, NiCl2 and CuCl2 lead to precipitation of chicken erythrocyte chromatin at a significantly lower concentration than the alkali earth metal chlorides MgCl2, CaCl2 and BaCl2. A similar distincti...

The presence oí aggregates oí humic substances (HS) with inorganic adsorbates in a lagaon located in Huelva (south Spain) ia reported. The chemical nature oftbe fulvic acid (FA) fraction, extracted froro the natura] aggregate by treatment with chelating resins, has been investigated by physical and chemical methods. Tbe results suggest that these FA are similar f.o FA from other aquatic environ...
