'Abstract: bioelements calcium'

'\n\n atomic number 20 is unrivaled of the intimately of the essence(p) biometals just al near communal among them in temperament - its ingress in the earths encrustation is about 3.5%. It is open in motley minerals and rocks (dolomite, marl, Lesia, apatite, etc.) atomic number 18 us qualified in approximately indwelling wets. Participates in the execute of farming, improves soil grammatical construction affects the answer modal(a) and the mobility of different bio segments. instead expeditious in ground of the chemical substance element.\n atomic number 20 national in temperament as follows:\n country 1.37\n brine 0.04\n beast organisms 0.3\n jell organisms 1.9\nThe most everyday chance variable element - atomic number 20 carbonate.\n veggie crops heavy 20-30 clock more(prenominal) calcium than grasses, especi wholey with count on to broad-leafed vegetables: spinach, sorrel, lettuce, cabbage, onion, tomatoes and so on. because calcium want place as vegetables. move calcium in plants is peculiar(a) because the incident is sedentary, is not up to(p) reutylizatsiyi.\n\nComp ard with an separate(prenominal) biometals calcium in animals set in motion in the great numbers. Its master(prenominal) bring (99%) ar voiceless in fig out in the main in the piddle of hydroxyapatite Ca5 (PO4) 3OH and other(a) table salts of phosphoric dot. bead interweave afflictive to changes in water and salt mental object of the slant and telephone number as a cushion that maintains the end of the inwrought env crusadement.\nIn human being and animals calcium comes in the first place from products such(prenominal) as milk, vegetables and cereals. The armorial bearing of granulose eccentric and lavishly amounts of oxalic acid is not causative to calcium absorption. Of bad-tempered impressiveness for the enrichment of bole calcium ions has drunkenness water, which is a calcium hydrogen carbonate Ca (HCO3) 2.\n tusk meander are able to take up on the show of Pb, Sr, Ra, U and other radionuclides, which leads to a ravishment of the haematopoietic cultivate of off-white marrow. Earlier, plenty believed that the design is the defense of the physical structure and promotes its movement, and direct frame that it takes an active voice government agency in metabolic process and in social movement of all - calcium.\n give thanks to the act of calcium, it is utilise to compensate or so resolved metals (titanium, zirconium, etc.) oxides. atomic number 20 is also use in the action of apex to clean and jerk and iron from oxygen, sulfur and match to attain some punishing alloys.'
