I-Vitamin D3 (i-Cholecalciferol) I-CAS: 67-97-0 Umhlinzeki Womkhiqizi

I-Vitamin D3 ingagcina i-metabolism ejwayelekile ye-calcium ne-phosphorus, ikhuthaze ukumuncwa kwe-calcium ne-phosphorus emzimbeni. Uma ingekho, kulula ezinganeni ukuthola ama-rickets. I-Vitamin D iyi-vitamin encibilikayo emafutheni. Kunezinhlobo eziningi zamakhemikhali ezaziwa ngokuthi zinomphumela we-vitamin D. I-Vitamin D2 ne-vitamin D3 zinokubaluleka okubalulekile okusebenzayo okutholakala kuma-steroid angenazo izilinganiso. I-D3 inikezwa kuqala emhlabeni, "Izindinganiso Zomhlaba Wonke" ze-vitamin D ziyi-crystalline D3 emsulwa. Umsebenzi oyinhloko we-vitamin D ukumuncwa kwe-calcium, i-phosphorus. Kunzima ukukhuthaza ukumuncwa kwe-calcium ne-phosphorus kanye ne-calcification yamathambo. Uma umzimba ungenayo i-vitamin D, ikhono lokumuncwa kwe-calcium ne-phosphorus lizoncipha, futhi okuqukethwe kwe-calcium ne-phosphorus egazini kuzoncipha. Ngemuva kwalokho i-calcium ne-phosphorus azikwazi ukufakwa ezicutshini zamathambo, ngisho nosawoti wamathambo uzoncibilika futhi uvimbele i-calcification yamathambo. Ukuntuleka kwe-vitamin D ezinganeni kuzothola ama-rickets. Ukuntuleka kwe-vitamin D kubantu abadala kuzothola i-osteomalacia. AmaJapane athanda ukukhiqiza nokusebenzisa i-D2. Ezidingweni ezahlukahlukene, inani lemithi lingu-30%, izithasiselo zokudla zingama-65%, kanti izithasiselo zokudla zingama-5%. Ngokusho kwe-"food fortifier use of health standards (1993)" ekhishwe yi-Ministry of Health, i-D2 ne-D3, njengezithasiselo zokudla okunempilo, zingasetshenziswa ubisi oluwuketshezi, i-margarine, imikhiqizo yobisi kanye nokudla kwezingane. Imithi yamavithamini. Ngokuyinhloko ingakhuthaza ukumuncwa kwamathumbu kanye nokufakwa kwe-calcium ne-phosphorus ekwelapheni ama-rickets kanye ne-osteomalacia. Isetshenziswa kakhulu ekudleni, emikhiqizweni yezempilo kanye neminye imikhiqizo ehlobene.
