calcium wikipedia the free encyclopedia

Calcium Simple English , the free encyclopedia

Its mass number is about 40.08. Calcium is very important in the human body, for making bones and for other purposes. Properties[change change source] Physical In vertebrates, calcium ions, like many other ions, are of such vital importance to many physiological processes that its concentration is maintained within specific limits to ensure adequate homeostasis. This is evidenced by human plasma calcium, which is one of the most closely regulated physiological variables in the human body. Normal plasma levels vary between 1 and 2% over any given tiCalcium in biology

Calcium metabolism

Calcium is the most abundant mineral in the human body. [3] The average adult body contains in total approximately 1 kg, 99% in the skeleton in the form of calcium Calcium supplements are salts of calcium used in a number of conditions. Supplementation is generally only required when there is not enough calcium in the diet. [2] [3] By mouth Calcium supplement

Calcium phosphate

Calcium phosphates are white solids of nutritional value [2] and are found in many living organisms, e.g., bone mineral and tooth enamel. [3] In milk, it exists in a colloidal form in micelles bound to casein protein with magnesium, zinc, and citrate –collectively referred to as colloidal calcium phosphate (CCP). [4]Calcium imaging is a microscopy technique to optically measure the calcium (Ca 2+) status of an isolated cell, tissue or medium.Calcium imaging takes advantage of calcium indicators, fluorescent molecules that respond to the binding of Ca 2+ ions by fluorescence properties. Two main classes of calcium indicators exist: chemical indicators and Calcium imaging

Calcium metabolism

Calcium metabolism. The body regulates calcium homeostasis with two pathways; one is signaled to turn on when blood calcium levels drop below normal and one is the pathway that is signaled to turn on when blood calcium levels are elevated. Calcium metabolism is the movement and regulation of calcium ions (Ca 2+) in (via the gut) and out (viaCalcium sulfide is a chemical compound made of one calcium atom and one sulphide atom.

Dicalcium phosphate Simple English , the free encyclopedia

Properties. Dicalcium phosphate is a white solid. It does not dissolve in water. It can be thought of as phosphoric acid where two of the hydrogen ions are replaced with calcium ions.. Preparation. It can be made by reacting phosphoric acid with calcium hydroxide.It can also be made by reacting sulfuric acid with a certain amount of tricalcium phosphate.Hard water is water that has a high mineral content (contrast with soft water ). The main components of these minerals usually are calcium (Ca 2+) and magnesium (Mg 2+) ions. But there are also dissolved metals, bicarbonates, and sulfates.

Sodium-calcium exchanger

The sodium-calcium exchanger (often denoted Na + /Ca 2+ exchanger, exchange protein, or NCX) is an antiporter membrane protein that removes calcium from cells. It uses the energy that is stored in the electrochemical gradient of sodium (Na + ) by allowing Na + to flow down its gradient across the plasma membrane in exchange for the countertransport Reactivity series. In introductory chemistry, the reactivity series or activity series is an empirical series of metals, in order of chemical reactivity from highest to lowest. It is used to summarize information about the chemical reactions of metals with acids and water, single displacement reactions and the extraction of metals from their ores.Reactivity series Simple English , the free encyclopedia
