Sitraydh Calcium, dabeecad, farsamo garoomada, isticmaalka

bulk ee Ca in jidhka qof qaangaar ah (oo ku saabsan 99%) ku jira unugyada lafuhu ka kooban kiristaalo hydroxyapatite. In serum nuujiya ugu, fiirsashada calcium wuxuu ku saabsan yahay 3 mmol / l (10-12 mg / 100 ml) oo waa joogto. isbedbedelka Daily of geysid ma ka badnaan 3-5%. Ca waa lagama maarmaanka u ah hawlaha caadiga ah ee habka dareemayaasha jirka. muruqyada The synapses udhigo calcium kor u sii daayo reer acetylcholine iyo xarunta choline la receptor, iyo marka ay cholinesterase xad acetylcholine shaqeysiin - Insaymkaas ah in hydrolyzes acetylcholine.

udhigo Ca ku jira reticulum ku sarcoplasmic, kor u wada falgelidda actin iyo myosin, hoos i.e. macdantaa muruqa. saamayn Tani waa la fuliyay in joogitaanka udhigo magnesium.

udhigo Calcium dhaqaajiso habka enzymatic ku jira marxaladaha hore ee xinjirowga dhiigga - in formation of thrombin iyo thromboplastin. The qabanaya of udhigo calcium in oxalate plasma ama sitraydh ka hortagtaa xinjirowga dhiigga.

Recently cadaato doorka gaarka ah ee calcium in dhaqdhaqaaqa gacanta, kaas oo cytoplasm ah, ay fiirsashada kama badna 10-6 jirjirroolaha. At heerka gacanta, waxaa jira lix hababka aasaasiga ah nafsaaniga ah in ay ku xiran tahay midda of udhigo calcium:

a) waxqabad motor of unugyada (muruqa);

b) excitability ee unugyada oo ay awoodaan in ay curiyaan electrostatic iman kara tallaabo (cabirida xaalada muruqa, dareemayaasha Suu photoreception foosha wadnaha);

c) kabsaday maadooyin uu ku dhexsameeysmo gacanta (dheecaan hoormoonada iyo neurotransmitters);

g) noqoshada ee walxaha milma ee gacanta by vesiculation (phagocytosis);

d)-shiid ah intracellular (Avv of glucose, lipolysis, iwm);

e) dhalmo cell (maytosis iyo oocytes unugyada labka iyo dheddiga, motility manida).

udhigo Ca wada jir ah ula borotiinada gaar ah siiyaan barti iyo qalbi engegnaantooda lafta. daawo Modern isticmaalaa diyaarinta badan oo ay ku jiraan udhigo oo kaalshiyam ah (glyukanat, sitraydh, chloride, lactate, carbonate, phosphate, iwm). sitraydh Calcium waa muhiim gaar ah. yada ugu weyn ee loo sii daayo calcium ka kaxeynayo (phosphates, sulfates, chlorides) ay la qaybaha organic iyo macdanta ee cuntada ka dhacdaa caloosha sarkhaansan chloride acid iyo falgalka proteolytic. Carbonic acid iyo phosphoric acid cusbo calcium ee dhexdhexaad ah acidic ee caloosha waxaa duco, iyo calcium ee foomka ionized ama adag la chelates L gala xiidmaha yar. Sidaa darteed, in la dhimay secretory shaqada caloosha helitaanka Ca nuugid waa ku filnayn, waxay noqon kartaa mid ka mid ah sababaha hoos u dhaca dhaqaalaha ee element this ee jirka. sitraydh Calcium waxaa sida ugu wanaagsan kala diri ee deegaanka acidic ee caloosha. calcium Ionized dhaba guskiisa xuubka noolaha, xataa iyada oo caqabad mandheerta. Qaybta waaweyn (80%) ka mid ah calcium raaca saxarada, kaadida wax soo saarka ee ku saabsan 20%. Maxaa yeelay, calcium sitraydh cusbo halkii sitraydh kor u hoos of oxalate kaadida, isticmaalka daroogada ma keeni formation of dhagxaan kellida.

Waxaa la ogaaday in habeenkii shaqeysiin doorashada ee cusbada macdanta jirka. Maxaa yeelay, dhakhaatiirta talineynaa qaadashada sitraydh calcium galabtii ama fiidkii. Tijaabiyeen la xiriirta correlative xun u dhexeeya dose ee calcium diyaarinta iyo hawl dawooyinka. Maxay ka dhigan tahay? sitraydh calcium waxaa ka wanaagsan ee jidhku u nuugo in yar ka qaataan. Sidaa darteed waxaa ugu wanaagsan in ay qaataan daawada dhawr jeer maalintii. Waayo, koox da 'kasta aasaasay caadooyinka calcium isticmaalka nafsaaniga ah. Calcium qoray sida ka hortagga iyo daweynta (rickets, osteoporosis, osteomalacia, waayo, xoojinta dhaldhalaalka ilkaha) Ujeeddada. sitraydh potassium waa la qoray, waayo, wadnaha, dhiig-karka, caadi ah ee salka acid iyo dheelitirka biyaha-cusbo ah ee jirka ku.
