IVithamini D3 (iCholecalciferol) I-CAS:67-97-0 Umthengisi woMvelisi Umfanekiso oPhambili

I-Vitamin D3 (iCholecalciferol) I-CAS:67-97-0 Umthengisi woMvelisi

I-Vitamin D zizinto eziphuma kwi-steroid. Ligama eliqhelekileyo leekhompawundi ezinezakhiwo ezifanayo kwaye zinefuthe lokukhula okuqhelekileyo kwamathambo kunye nokugcinwa kwawo. Okwangoku, kukho ubuncinane iintlobo ezingaphezu kweshumi ze-sterol ezinomsebenzi we-vitamin D. Kodwa kukho izinto ezimbini ezibalulekileyo kuphela, ezaziwa ngokuba yi-pro-vitamin D. Enye yi-ergosterol ekhoyo kwioyile yemifuno okanye kwimvubelo, enokuvelisa i-vitamin D2 xa ikhanyiswe lilanga okanye yimisebe ye-ultraviolet. Ikwaziwa nangokuthi yi-cholecalciferol okanye i-ergocalciferol. Enye yi-7-dehydrochlesterol ekhoyo eluswini. Iya kuba yi-vitamin D3 emva kokuba ikhanyiswe kukukhanya. Ikwabizwa ngokuba yi-cholecalciferol. I-D2 kunye ne-D3 zinezakhiwo ezifanayo. Zii-B ring derivatives ze-sterol. Umahluko kukuba uthotho lwe-side chain ye-vitamin D2 luneqela le-methyl kunye ne-double bond enye.

Ukusetyenziswa kunye nesiphumo

IVithamini D3 inokugcina imetabolism eqhelekileyo yecalcium kunye nephosphorus, ikhuthaze ukufunxwa kwecalcium kunye nephosphorus emzimbeni. Xa ingekho, kulula kubantwana ukufumana ii-rickets. IVithamini D yivithamini enyibilikayo kumafutha. Kukho iikhompawundi ezilishumi elinesibini ezaziwa ngokuba nefuthe levithamini D. IVithamini D2 kunye neVithamini D3 zibaluleke kakhulu kwi-steroid derivative. I-D3 inikwa phambili kwihlabathi liphela, "iMigangatho yaMazwe ngaMazwe" yevithamini D yikristale emsulwa yeD3. Umsebenzi ophambili weVithamini D kukusetyenziswa kwecalcium, iphosphorus. Kunzima ukukhuthaza ukufunxwa kwecalcium kunye nephosphorus kunye ne-calcification yamathambo. Xa umzimba ungenayo iVithamini D, amandla okufunxwa kwecalcium kunye nephosphorus aya kuncipha, kwaye umxholo wecalcium kunye nephosphorus egazini uya kuncipha. Emva koko icalcium kunye nephosphorus azinakufakwa kwizicubu zethambo, netyuwa yethambo iya kunyibilika kwaye ithintele i-calcification yamathambo. Ukungabikho kweVithamini D kubantwana kuya kufumana ii-rickets. Ukungabikho kweVithamini D kubantu abadala kuya kufumana i-osteomalacia. AmaJapan athanda ukuvelisa nokusebenzisa i-D2. Kwiimfuno ezahlukeneyo, ubungakanani bamayeza yi-30%, izongezo zokutya yi-65%, kwaye izongezo zokutya yi-5%. Ngokwe "ukusetyenziswa kwemigangatho yezempilo yokutya (1993)" ekhutshwe yiSebe lezeMpilo, i-D2 kunye ne-D3, njengezongezo zesondlo, zingasetyenziselwa ubisi olumanzi, i-margarine, iimveliso zobisi kunye nokutya komntwana. Amayeza eevithamini. Ngokuyintloko inokukhuthaza ukufunxwa kwamathumbu kunye nokugcinwa kwe-calcium kunye ne-phosphorus kunyango lwe-rickets kunye ne-osteomalacia. Isetyenziswa kakhulu ekutyeni, kwiimveliso zempilo nakwezinye iimveliso ezinxulumene noko.
