Zinc(II) ions are catalytic, structural, and regulatory cofactors in proteins. In contrast to painstakingly collecting the pieces by isolating and characterizing zinc proteins, 'omics' approaches are now allowing us to tease out information about zinc proteins from genomes and to piece together the information to a broader knowledge and appreciation of

Zinc tolerance tests in zinc deficient and zinc supplemented diets [PDF]
The American Journal of Clinical Nutrition, 1986 Seven men consumed a low-zinc (3.3 mg/day) diet for 8 wk, followed by zinc-repletion (+15 mg/day) for 12 days. Zinc tolerance tests (50 mg) were administered initially and following depletion and repletion periods. Plasma zinc after 2 h in the zinc tolerance test was marginally higher after both the depletion (p less than 0.06) and repletion (p less ...

European Journal of Drug Metabolism and Pharmacokinetics, 1982
In this study the authors compared the pharmacokinetics of three zinc salts after parenteral and oral administration to rabbits: zinc sulfate, a soluble mineral salt; zinc pantothenate, a soluble organic salt; and zinc orotate, an insoluble organic salt. The results obtained with the two soluble salts were not significantly different (p less than 0.05).

Nutritional deficiency of zinc is widespread throughout the developing countries and a conditioned deficiency of zinc is known to occur in many diseased states. Zinc is known to play an important role in the immune system and zinc deficient subjects may experience increased susceptibility to a variety of pathogens. We have studied the effects of a mild

Experimental evidence exists to suggest that zinc can have positive and negative effects on the physiology of cells depending on the "local" concentration, localisation (extracellular vs. intracellular) and/or state (bound vs. free). The retina contains particularly high amounts of zinc suggesting a pivotal role in the tissue.

Abstract This article describes the zinc and zinc alloys for decorative and functional applications. It focuses on the types of zinc coatings, namely, hot dip galvanizing, electrogalvanizing, metallizing, and mechanical galvanizing. The article covers the uses of zinc alloy castings, including pressure die castings, and gravity castings.

Zinc-directed inhibitors for zinc proteinases
Acta Crystallographica Section D Biological Crystallography, 1995Zinc proteinases have been recognized as a distinct class of proteolytic enzymes in which at least one ion of zinc is involved directly in catalysis. This family includes a growing number of biologically important enzymes which are attractive targets for rational drug design. In this paper we examine the special features of the zinc binding environment
