Calcium citrate: āhuatanga, tikanga o te mahi, te whakamahi o

Ko te nuinga o Ca i roto i te tinana pakeke (e pā ana ki 99%) i roto i roto i te wheua kikokiko arā, o tioata hydroxyapatite. I roto i te serum te nuinga kararehe, te konupūmā kukū ko e pā ana ki 3 mmol / l (10-12 mg / 100 ml) me he tamau. rerekē Daily o te taimau kore e nui ake 3-5%. mea faufaa no te mahi noa o te pūnaha io Ca. Ko te uauaio synapses katote konupūmā whakatairanga tuku o acetylcholine me Matuorakouawai pūhui ki tona receptor, a ka whakahohe i te cholinesterase te taikaha acetylcholine - he paru e hydrolyzes acetylcholine.

E roto katote Ca i te reticulum sarcoplasmic, whakatairanga taunekeneke i waenganui i actin me myosin, i.e. whakaiti o muka uaua. kawea ana tēnei pānga i roto i te aroaro o katote konupora.

whakahohe katote konupūmā te tukanga enzymatic i roto i te wāhanga tuatahi o te upoo- toto - i roto i te hanganga o te thrombin me thromboplastin. Ko te here o ngā katote konupūmā i roto i te oxalate wē ranei ārai citrate upoo- toto.

Aita i maoro a'e whakamatauria tūranga ahurei o te konupūmā i roto i te mahi pūtau, i roto i nei te cytoplasm, e kore e tona kukū nui 10-6 kamiriona. I te taumata pūtau, i reira e ono tukanga whaiaroaro taketake e whakawhirinaki i runga i te kukū o ngā katote konupūmā:

he) mahi nekeneke o ngā pūtau (uaua hukihuki);

b) te excitability o ngā pūtau e he taea ki te whakaputa hiko pea mahi (oro uaua, karere hihiko photoreception hukihuki cardiac);

c) ora matū e kua synthesized i roto i te pūtau (secretion o hormones me neurotransmitters);

g) te whakaurunga o ngā matū wairewa i roto i te pūtau e vesiculation (phagocytosis);

d) te pākia intracellular (kōtuitanga o te kūhuka, lipolysis, me ētahi atu);

e) reproduction pūtau (whāū me oocytes kikiritanga, parāoa motility).

Ca katote tahi me pūmua motuhake whakarato elasticity me te pakeke o te wheua. whakamahi rongoā Modern maha teuteu kei roto katote o te konupūmā (glyukanat, citrate, pūhaumāota, lactate, pākawa waro, Phosphate, me ētahi atu). Ko te konupūmā citrate o faufaa ngā. Ko te atamira matua o te tuku konupūmā i ona complexes (phosphates, pūkawa, te pūhau) ki organic me te kohuke wāhanga o te kai puta i roto i te kopu i raro i te mana o te pūhaumāota waikawa me whākōkī proteolytic. E dissociated Carbonic waikawa me te waikawa phosphoric konupūmā tote i roto i te reo waikawa o te puku, me te konupūmā i roto i te puka ionized ranei i roto i te matatini ki chelates wairewa tomo te whēkau iti. Na reira, i roto i te secretory iti mahi o te puku wātea he iti Ca momi, ka taea e te mea tetahi o nga take mo te tarepa o tenei huānga i roto i te tinana. Kei te pai rewa konupūmā citrate i roto i te taiao waikawa o te puku. konupūmā Ionized noa te ô i kiriuhi koiora, ara i roto i te arai ewe. Ko te wahi nui (e pā ana ki 80%) o te konupūmā excreted i feces, mimi putanga o e pā ana ki 20%. No te mea whakatairanga konupūmā citrate tote kaua citrate whakaiti o oxalate i te mimi, e kore te whakamahi o te tarukino i arahi ki te hanganga o kohatu tākihi.

Kei te kitea te reira e i roto i te po whakahohe kōwhiringa o Mariao kohuke i te tinana. No te mea tākuta tūtohu tango konupūmā citrate i roto i te ahiahi ahiahi ranei. Whakamatauria pā ana correlative kino i waenganui i te horopeta o te konupūmā faaineineraa me mahi ho'oraa. Eaha te auraa? te konupūmā citrate pai riro e te tinana i roto i pota iti. Na reira ko te reira pai ki te tango i te tarukino e rave rahi taime i te ra. Hoki ia rōpū pakeke whakapumautia whaiaroaro tikanga konupūmā kohi. Konupūmā whakaritea rite te taupā me whakaora (kōiwi, osteoporosis, osteomalacia, hoki te whakapakari i niho i tohu) whakaaro. i whakaritea pāhare pāporo citrate te mo te kore te ngakau, takawhita, māori o te waikawa-turanga, me te toenga wai-tote i roto i te tinana.
