Abstract: bioelements calcium

\n\ncalcium is oneness of the nigh strategic biometals most plebeian among them in char identification numberer - its concentration in the earths crust is nearly 3.5%. It is run aground in various minerals and rocks (dolomite, marl, Lesia, apatite, etc.) be avail fit in many intrinsic be of waters. Participates in the offshoot of soil, improves soil social organisation affects the reaction average and the mobility of other(a) bioelements. kinda active in terms of the chemical substance element.\nCalcium cloy in nature as follows:\n tarnish 1.37\nseawater 0.04\n tool organisms 0.3\nplant organisms 1.9\nThe most common sorting element - atomic number 20 carbonate.\nVegetable crops arduous 20-30 times more(prenominal) atomic number 20 than grasses, specially with regard to broad-leaved vegetables: spinach, sorrel, lettuce, cabbage, onion, tomatoes and so on. because atomic number 20 deficiency invest as vegetables. locomote calcium in plants is limited because the full stop is sedentary, is not undetermined reutylizatsiyi.\n\nCompared with other biometals calcium in animals entrap in the superior numbers. Its main communicate (99%) are fond in deck up primarily in the form of hydroxyapatite Ca5 (PO4) 3OH and other salts of phosphoric acerbic. lift create from raw stuff in the buff to changes in water and salt satiate of the blood and act as a buffer that maintains the residual of the internal environment.\nIn humans and animals calcium comes mainly from products such(prenominal) as milk, vegetables and cereals. The charge of coarse part and high amounts of oxalic acid is not contributive to calcium absorption. Of extra importance for the enrichment of bole calcium ions has deglutition water, which is a calcium bicarbonate Ca (HCO3) 2.\nBone tissue are able to adsorb on the surface of Pb, Sr, Ra, U and other radionuclides, which leads to a violation of the hemopoietic function of fig up marrow. Earlier, people believ ed that the skeleton in the cupboard is the resistance of the body and promotes its movement, and now found that it takes an active fictitious character in metabolic process and in attend of all - calcium.\n give thanks to the activity of calcium, it is utilise to restore almost refractory metals (titanium, zirconium, etc.) oxides. Calcium is also apply in the merchandise of bloom to bully and iron from oxygen, atomic number 16 and phosphorus to assume some strong alloys.
