Shifts in zinc's location could be exploited for early diagnosis of prostate cancer Zinc, an essential nutrient, is found in every tissue in the body. The vast majority of the metal ion is tightly bound to proteins, helping them to perform biological reactions. Tiny amounts of zinc, however, are only loosely bound, or "mobile," and thought to be critical for proper function in organs such as the brain, pancreas, and prostate gland. Yet the exact roles the ion plays in biological systems...

Study recommends continuing zinc application at critical stages on apple trees Zinc is vital for the healthy growth and reproduction of all organisms. In plants, zinc plays a key role in essential functions such as carbohydrate metabolism, photosynthesis, and sugar and starch synthesis. Apple, one of the world's most popular fruits, tends to be highly susceptible to zinc deficiency. A new study in HortTechnology recommends new protocols for using zinc sprays at critical stages on apple...

Copper is a chemical element in the periodic table that has the symbol Cu and atomic number 29. Notable characteristics Copper is a reddish-coloured metal, with a high electrical and thermal conductivity (among pure metals at room temperature, only silver has a higher electrical conductivity). Copper may well be the oldest metal in use, as copper artifacts dating to 8700 BC have been found. Besides being part of various ores, copper can be found in the metallic form (i.e. native copper)...

Smithsonite, or zinc spar, is zinc carbonate ZnCO3, a mineral ore of zinc. Historically, smithsonite was identified with hemimorphite before it was realised that they were two distinct minerals. The two minerals are very similar in appearance and the term calamine has been used for both, leading to some confusion.

Zinc is a chemical element in the periodic table that has the symbol Zn and atomic number 30. Notable characteristics Zinc is a moderately reactive metal that will combine with oxygen and other non-metals, and will react with dilute acids to release hydrogen. The one common oxidation state of zinc is +2. Applications Zinc is the fourth most common metal in use, trailing only iron, aluminium, and copper in annual production. - Zinc is used to galvanize metals such as steel to...
