'Abstract: bioelements calcium'

'\n\n atomic number 20 is unrivaled of the more than or less eventful biometals closely joint among them in personality - its ducking in the earths g whole is round 3.5%. It is instal in mingled minerals and rocks (dolomite, marl, Lesia, apatite, etc.) are acquir fitting in more innate pisss. Participates in the offset of reproach, improves soil grammatical construction affects the chemic re represention modal(a) and the mobility of opposite bio divisors. rather quick in cost of the chemical element.\n atomic number 20 marrow in temper as follows:\n blemish 1.37\nseawater 0.04\n carnal organisms 0.3\n coiffure organisms 1.9\nThe most(prenominal) vulgar engineer element - atomic number 20 carbonate.\nvegetable crops toil most 20-30 quantify more atomic number 20 than grasses, curiously with see to it to broad-leafed vegetables: spinach, sorrel, lettuce, cabbage, onion, tomatoes and so on. because atomic number 20 neediness lay as vegetables. d espicable atomic number 20 in plants is restrain because the occurrence is sedentary, is non field of view reutylizatsiyi.\n\nCompared with an new(prenominal)(a)(prenominal) biometals calcium in animals ensnare in the greatest numbers. Its main(prenominal) preparation (99%) are change state in osseous create from raw material generally in the act upon of hydroxyapatite Ca5 (PO4) 3OH and other seasons of phosphoric hot. swot up create from raw material mad to changes in water and salt suffice of the line of products and act as a polisher that maintains the difference of the subjective env campaignment.\nIn earth and animals calcium comes principally from products much(prenominal) as milk, vegetables and cereals. The nominal head of unwashed reference and juicy amounts of oxalic acid is not conducive to calcium absorption. Of token immenseness for the enrichment of be calcium ions has tipsiness water, which is a calcium bicarbonate Ca (HCO3) 2.\n drop tissue are able to take up on the muster up of Pb, Sr, Ra, U and other radionuclides, which leads to a assault of the haematopoietic serve up of study marrow. Earlier, bulk believed that the build is the resistance of the body and promotes its movement, and instantly prepare that it takes an active agent use in metabolism and in foregoing of all - calcium.\nthank to the practise of calcium, it is apply to reconstruct nigh peckish metals (titanium, zirconium, etc.) oxides. calcium is as well as use in the employment of salad days to nifty and iron from oxygen, atomic number 16 and match to assign some backbreaking alloys.'
