Uhlalutyo lubonisa ukuba i-25-OH ivithamin D?

iimvavanyo igazi ukulinganisa izinga vitamin eyenziwe ukuze sibone yokuphazamiseka nethe, kwakunye nokubeka esweni imeko yesigulane, nto leyo uchongwe amayeza eziqulathe vitamin esebenzayo D. Bhalani isifundo kuyo nayiphi kwilebhu yezonyango, apho uza kufumana isiphumo uguqulwa. Loo uphethwe yini kuyimfuneko, ugqirha oqeshwe yi Iimpawu ezithile. Eli nqaku liza kukhangela oko ivithamin D, iinzuzo zayo umzimba, kwakunye nendlela zohlalutyo ukuchonga le vitamin.

malunga vitamin

Le element ezisebenza ezahlukeneyo kwemisebenzi. Vitamin D lilawulwa ngokutshintshiselana phosphorus kunye calcium ebantwini. Phosphorus imibala akukho isongelwa malunga nabani na, kodwa calcium ngxaki yingozi empilweni. ukungabikho Strong of ivithamin D ebantwaneni kunokubangela yamathambo abadala nayo kukhokelela ukuthambisa amathambo kunye nengozi yokuba waphuka. Oku kubangela iingxaki emazinyweni. Le element normalizes imisebenzi luvo, iiproteins ukutya, ikhuthaza ekukhuleni iiseli ezibomvu zegazi kwandisa ukuxhathisa kusuleleko.

Ukongezelela ukuncedisa ukufunxeka calcium iphosphate, ivithamin D onesiphumo phezu abanamajoni omzimba yonyango. Yena uyakwazi 'ukucima "yaye" ziquka "100-1250 20000-30000 ngezakhi sikhona nakubantu. Ekubeni Ukwanda eziphilayo njengako vitamin zehlisa umngcipheko zizifo sentliziyo, umhlaza kunye nezifo sokuhlasela. Namhlanje kuqhutywa izifundo eziphambili kwi Vitamin D luncedo kwi unyango kunye nothintelo lwezifo ezahlukeneyo.

Mhlawumbi uyazi wena, ukuba vitamin D olwavezwa eluswini phezu elangeni. Kuye kwafunyaniswa nangakumbi lufumaneka iintlobo ezithile iimveliso zezilwanyana (kwesibindi, inyama yehagu, yenkomo cod, mackerel, ioli cod isibindi, iqanda sac) kunye nemifuno (amakhowa ezifana chanterelles neenkowane). Hi ndlela leyi, lwesi sakhi siyakhuselwa kakuhle ngexesha upheka. oyile Yemifuno kunye amafutha ezilwanyana igalelo nokwenziwa ngokupheleleyo ngumzimba.

Emva koko, sele iqhuba esibindini is kuguquka vitamin 25 hydroxycholecalciferol-, okanye 25-OH. Ukuze sibone indlela entle bazaliswa umzimba womntu, uhlalutyo lwenziwa ivithamin D (25-OH). Ngoko 25-hydroxycholecalciferol kwi kidney iguqulelwa uhlobo esebenzayo eyenza uninzi umsebenzi. Emva Yindibanisela ivithamin D eluswini ivavanywa inguqu kwesibindi, kwandula nezintso. isifo sezintso Chronic kunokubangela ukuswela lo mzimba, nokuba bahlale ezaneleyo elangeni.

Iinzuzo ivithamin D abantwana, amadoda kunye nabafazi

Phantse isinye kwisithathu ngabafazi xa exesheni, ubunzima ngenxa yokuba izimbiwa leached ukusuka amathambo, le nkqubo ibizwa ngokuba osteomalacia. Ngenxa yoko, ubungozi Ukophuka kwamathambo.

Amadoda amakhulu nabo phantsi kwamathambo kunye osteomalacia, nangona kaninzi ngaphantsi abafazi. Ngoko ke, kufuneka uphumelele uvavanyo ukuze ivithamin D 25-OH. Njengoko unyango kunye nothintelo uya kumisela ukuthatha novithamini D. Kwakhona, kunye nobudala ukukwazi komzimba ukuze nokulungelelanisa le vitamin xa zidibene nelanga mandundu.

Ezinye izifundo kubonisa ukuba lulutho ivithamin D abantu abagulayo kunye ukhwekhwe. Ngapha koko, oku kunciphisa amathuba zizifo sentliziyo, izifo samathambo kunye nomhlaza.

Ngokuba abantwana vitamin D kubalulekile ekwenzeni ekuthinteleni yamathambo kunye neengxaki amazinyo. Kodwa musa ukulibala ukuba iivithamini D2 kunye D3 aba ilikhubalo lokunyanga zonke izigulo ehlabathini. Kodwa ukuba ufunde kabanzi ngazo umntu ayinakukukhathaza.

namazinga

Vitamin D ngokuqhelekileyo zifumaneka igazi abasetyhini kunye namadoda bonke ubudala, intsha, abantwana neentsana malunga efanayo abadala. Kodwa ke mna ndithi ukuba intsebenzo yalo kunokwahluka ngokuxhomekeka:

• ubudala (abantu abadala babe kwinqanaba elisezantsi);
• ixesha;
• uhlobo ekudleni.

A ukuhla ivithamin D ngexesha lokukhulelwa.

I omdala umntu ufumana, ukuba kunzima kakhulu ukuphumeza isalathisi eqhelekileyo ivithamin D, ngenxa ukwaluphala kuguga imveliso umzimba phantsi kwelanga yale vitamin. Kuba siyakwazi ukuthetha awushiye yokuthatha ivithamin D ebudaleni. Kuba abantu abadala abafumana la machiza kuba luncedo ngakumbi kunokuba yentsana kunye nabasetyhini abakhulelweyo. Abantu abamnyama banyanzelwa ukuba baphile kweli lizwe kunye nemozulu epholileyo lisibekele, akakwazi ukwenza ngaphandle kokuthatha ivithamin D azipilisi. Ngapha koko, lo mnyama umbala, yokuba kuveliswe le vitamin na ngaphantsi baboniswa UV eyingozi.

Uhlalutyo ukujonga izinga ivithamin D

Ukuze ubone uyondelelwano lwee- uhlalutyo kwenziwa ngomhla wama-25-OH (hydroxyl) novithamini D. Thina sele siyazi ukuba ubuncwane yenziweyo isibindi, kwaye ke kufanele kube kwi izintso, ukuze ingaguqulwa njani na ibe uhlobo esebenzayo.

Phi na lo hlalutyo? Thatha igazi ivithamin D kufuneka amaziko ikakhulu ezikhethekileyo ze hormone, kunye yintoni kuthiwe:

• Uhlalutyo 25-OH (hydroxyl) ivithamin D uphando ngokukhawuleza - iintsuku 1-2.
• Uyakwazi ukufumana iziphumo nge email.
