Calcium citrate is the calcium salt of citric acid. It is commonly used as a food additive, usually as a preservative, but sometimes for flavor. In this sense, it is similar to sodium citrate. Calcium citrate is also used as a water softener because the citrate ions can
Calcium Absorption—A Paradigm for Mineral Absorption …
A nuer of mineral ions—Ba, Sr, Mn, the lanthanides, Pb—compete with calcium for calbindin, some binding more tightly than calcium (Fullmer and Wasserman 1977). Induction of calbindin can explain why vitamin D administration enhances lead absorption ( Fullmer 1992 ).

The strontium fortified calcium compounds contain calcium ions, calcium atoms, strontium ions, strontium atoms, and coinations thereof and one or more anions. Exemplary anions include, but are not limited to, citrate, phosphate, carbonate, and coinations thereof.
Controlling Metal Ion Fouling in Industrial Water Systems
calcium phosphate precipitation inhibitors and also as iron oxide dispersants.8,9 This paper presents new results of an ongoing effort to investigate fouling by metal oxide/hydroxide with particular emphasis on aluminum, iron, manganese, and zinc ions.
Expt 2 Calcium by visible spectroscopy
Soluble calcium (as Ca 2+ ions) in aqueous samples is usually determined by EDTA titration using Eriochrome Black T as indior. In very dilute solutions, titration becomes impractical to use due to low levels of calcium ions which make the color change at

Boon and Bane of Metal Ions in Medicine | Science
Metal ions contained within well-designed molecules already constitute a great boon for the medicinal pharmacopoeia. However, whether essential or not, the threshold for toxicity can be very low. One of the challenges of designing metal-based drugs is to balance the potential toxicity of an active formulation with the substantial positive impact of these increasingly common therapeutic and

Chelated Fertilizers and Their Use
Metal chelation is important because it makes metal ions more available for uptake by plants. Positively charged metal ions, such as Zn+2, Mn+2, Cu+2 and Fe+2, readily react with negatively charged hydroxide ions (OH-), making them unavailable to plants.
Sodium Citrate - The Chemical Company
Antioxidant: The citrate ion is a powerful chelating agent for trace metal ions. Blood anticoagulant: The citrate ion will chelate calcium, thereby reducing the tendency for blood to clot. Diuretic – potassium citrate has diuretic properties. Clinical Nutrition Medical
INTERACTION OF CELLULOSE WITH ALKALI METAL IONS AND …
Dependent on the type of metal ion present, binding of ions occurs via ion-exchange e.g. in case of calcium ions or via ligand exchange e.g. in the case of heavy metals. The type of metal ion to be inserted and selection of appropriate conditions for metal
US Patent Appliion for Low Water Stannous Fluoride …
These metal ions provide anti-gingivitis and anti-plaque benefits and may also improve breath and reduce sensitivity. Stannous fluoride has been used in dentistry since the 1950''s as a fluoride source to prevent dental caries. Similarly, zinc citrate has been shown
LapG, Required for Modulating Biofilm Formation by …
Biofilm formation by Pseudomonas fluorescens Pf0-1 requires the cell surface adhesin LapA. We previously reported that LapG, a periplasmic cysteine protease of P. fluorescens, cleaves the N terminus of LapA, thus releasing this adhesin from the cell surface and resulting in loss of the ability to make a biofilm. The activity of LapG is regulated by the inner merane-localized cyclic-di-GMP
