Calcium - Element information, properties and uses

Calcium is what is known as an essential element, meaning that it is an element which is absolutely necessary for life processes. Which is what the old milk TV adverts were trying to tell us after all. Calcium is used to produce the minerals contained in bones, shells and teeth through a process called biomineralisation.

Molybdenum - Wikipedia

2019-4-23 · Molybdenum does not occur naturally as a free metal on Earth; it is found only in various oxidation states in minerals. The free element, a silvery metal with a gray cast, has the sixth-highest melting point of any element. It readily forms hard, stable carbides in alloys, and for this reason most of world production of the element (about 80%) is used in steel alloys, including high-strength

Calcium - Magnesium ialance implied in benign

Calcium (Ca)- magnesium (Mg) ialance is implied in prostate cancer. Ca/Mg ratio increases or decreases with proliferation or apoptosis, respectively. The study examined whether this Ca/Mg ialance exists in BPH patients and the effect of a phytotherapeutic drug on the Ca/Mg ratio. Thirty (30) BPH patients who used the ethanolic root extract of Croton meranaceus (60 mg/day) for 3 months
