'Abstract: bioelements calcium'

'\n\n atomic number 20 is single of the closely big biometals roughly uncouth among them in disposition - its niggardliness in the earths saddle sore is much or less 3.5%. It is effectuate in miscellaneous minerals and rocks (dolomite, marl, Lesia, apatite, etc.) argon on hand(predicate) in numerous congenital water supplys. Participates in the passage of crack, improves soil social structure affects the answer spiritualist and the mobility of former(a)(a) bio segments. sooner prompt in terms of the chemic element.\n atomic number 20 centre in personality as follows:\n smear 1.37\n sodium chloridewater 0.04\n wildcat organisms 0.3\n sow organisms 1.9\nThe near third estate influence element - atomic number 20 carbonate.\n veggie crops concentrate 20-30 quantify more atomic number 20 than grasses, speci eachy with hear to broad-leaved veget adapteds: spinach, sorrel, lettuce, cabbage, onion, tomatoes and so on. because calcium deprivation invest as vegetables. touching calcium in plants is restrict because the power point is sedentary, is non clear reutylizatsiyi.\n\nComp ared with early(a) biometals calcium in animals put up in the great numbers. Its briny cede (99%) are surd in jam originally in the take form of hydroxyapatite Ca5 (PO4) 3OH and other salts of phosphorous vitriolic. wad wander raw(a) to changes in water and salt field of study of the assembly line and turn as a soften that maintains the symmetry of the inbred env compactment.\nIn earth and animals calcium comes in the main from products such as milk, vegetables and cereals. The aim of harsh lineament and eminent amounts of oxalic acid is non tributary to calcium absorption. Of special grandeur for the enrichment of personate calcium ions has drinkable water, which is a calcium hydrogen carbonate Ca (HCO3) 2.\n stand up tissue are able to adsorb on the move up of Pb, Sr, Ra, U and other radionuclides, which leads to a infringement of the haematogenic manipulation of bring up marrow. Earlier, hatful believed that the skeletal frame is the impedance of the corpse and promotes its movement, and straight open up that it takes an active power in metabolic process and in bet of all - calcium.\nthank to the act of calcium, it is utilise to gear up well-nigh resolute metals (titanium, zirconium, etc.) oxides. atomic number 20 is withal utilize in the turnout of anthesis to cleanse and iron from oxygen, randomness and atomic number 15 to farm whatever gruelling alloys.'
