3-Hydroxybenzylaminobenzoic acid synthesized in the laboratory as a reagent for the determination of zinc in various water samples. Zinc(II) reacts with 3-hydroxybenzylaminobenzoic acid and forms a light yellow colored complex at pH 5.0. The complex has a maximum absorbance at 460 nm. The complex is stable for more than twelve hours. Hence, a detailed study of the extraction of zinc(II) with 3-...

Zinc deficiency is a global nutritional disorder affecting majority of healthy people rather than those suffering from chronic diseases, affects about one third of people around the world and thereby causing clinical manifestations. This work represents new modality to increase the intestinal absorptivity and bioavailability of zinc from the diet by replacing traditional bulk form by zinc nanop...

BACKGROUND Zinc (Zn) biofortification through foliar Zn application is an attractive strategy to reduce human Zn deficiency. However, little is known about the biofortification efficiency and bioavailability of rice grain from different forms of foliar Zn fertilizers. METHODOLOGY/PRINCIPAL FINDINGS Four different Zn forms were applied as a foliar treatment among three rice cultivars under fie...

The chemical forms of zinc (Zn) in the Zn-tolerant and hyperaccumulator Arabidopsis halleri and in the non-tolerant and nonaccumulator Arabidopsis lyrata subsp. petraea were determined at the molecular level by combining chemical analyses, extended x-ray absorption spectroscopy (EXAFS), synchrotron-based x-ray microfluorescence, and muEXAFS. Plants were grown in hydroponics with various Zn conc...

Anthropogenic sources account for much of the zinc (Zn) in the environment. Constraining the isotopic composition of anthropogenic Zn is therefore essential to understanding the environmental biogeochemical cycling of Zn isotopes. This study examines the isotopic variability in several different categories of anthropogenic Zn. Pure Znmetal and Zn dust are the rawmaterials used in many Zn-contai...

We conducted two experiments using marginally Zn-deficient (-Zn) calves to determine which supplemental chemical form of Zn would most rapidly reverse certain Zn deficiency signs and to determine whether a change in protein turnover had occurred in Zn deficiency. In Exp. 1, 40 crossbred beef heifers were allocated by BW to four groups. The control group received 23 mg Zn/kg diet DM from ZnSO4 s...

Fig. 2. Sephadex G.75 elution profiles of kidney supernatants ofrats and mice injected with zinc. The kidney supernatants (10 ml/column) were applied to a Sephadex G-75 column, eluted with 1 mM Tris buffer solution (pH 8.6), and collected (5 ml/tube). -, Zn; and -, Cu. The arrow indicates the metallothionein fraction. RK and MK are abbreviated forms of rat kidney and mouse kidney, respectively....

Zinc is the second most abundant transition metal in the body. It is essential for most living beings. The human body contains approximately 2 g of zinc. It is mainly distributed in the blood, kidney, liver, bone, and brain. Zinc is a co-factor of more than 300 enzymes or metalloproteins. These zinc-related proteins play biologically important roles in mitotic cell division, protein synthesis, ...
