Incazelo
I-Vitamin B12 ebizwa nangokuthi i-cobalamin, ivithamini encibilikayo emanzini enendima ebalulekile ekusebenzeni okujwayelekile kobuchopho nesimiso sezinzwa, kanye nokwakhiwa kwegazi.
Ivamise ukubandakanyeka kumetabolism yawo wonke amangqamuzana omzimba womuntu, ikakhulukazi okuthinta ukuhlanganiswa kwe-DNA nokulawulwa, kodwa futhi kuhlanganiswe ne-fatty acid kanye nokukhiqizwa kwamandla. Isikhunta, izitshalo, noma izilwane azikwazi ukukhiqiza uvithamini B12. Amagciwane kanye ne-archaea kuphela anama-enzyme adingekayo ukuze kuhlanganiswe, nakuba ukudla okuningi kuwumthombo wemvelo we-B12 ngenxa ye-symbiosis yebhaktheriya. Ivithamini iyivithamini enkulu kunazo zonke futhi eyinkimbinkimbi kakhulu futhi ingakhiqizwa ezimbonini kuphela nge-bacterial fermentation-synthesis.
Izinzuzo Zomkhiqizo
Impilo Yengqondo
Ucwaningo lubonisa ukuthi i-vitamin B12 ingasiza ekusebenzeni kobuchopho nesimiso sezinzwa, inkumbulo, imizwa, nokucindezeleka. I-Vitamin B12 idlala indima ekukhiqizeni i-serotonin, ngakho-ke ukuntula kungase kuhlotshaniswe nokucindezeleka komtholampilo. Kolunye ucwaningo, abesifazane asebekhulile abakhubazekile abanokuntuleka kwe-B12 batholakala benengozi ephindwe kabili yokucindezeleka okukhulu kunalabo abangenakho ukuntula.
Ngaphezu kwalokho, amazinga e-vitamin B12 eqile ahlotshaniswa namathuba angcono okululama ekuguleni okukhulu kokucindezeleka.
Impilo Yesikhumba
I-Vitamin B12 iyaziwa ukusiza isikhumba, izinwele, nezinzipho. Ukushoda kwevithamini kuholela ekushintsheni kombala, isikhumba hyper pigmentation, vitiligo, ukuncipha ukukhula izinwele nokunye.
Impilo Yenhliziyo
Ucwaningo lubonisa ukuthi i-vitamin B12 yehlisa amazinga e-homocysteine egazini. I-Homocysteine i-amino acid exhunywe nokwanda kwesifo senhliziyo. Abacwaningi bathole ukuthi abantu abanamazinga aphezulu e-homocysteine banamazinga aphezulu okuhlaselwa yinhliziyo nesifo sohlangothi.
Isicelo
1. Izicelo zokunakekelwa kwezempilo kanye nezempilo
Isetshenziswa ekwelapheni ukuntuleka kwe-Vitamin B12 okuhlukahlukene, isibonelo: ukwelapha i-megaloblastic anemia, i-anemia ebangelwa ubuthi, i-aplastic anemia kanye ne-leukopenia psychosis; kanye nokusetshenziswa kwe-pantothenic acid, engavimbela i-anemia eyingozi, isiza ukutholwa kwe-Fe2 + nokukhishwa kwe-gastric acid; ibuye isetshenziselwe ukwelapha isifo sokuqaqamba kwamalunga, ukukhubazeka kwemizwa ebusweni, i-neuralgia ye-trigeminal, i-hepatitis, i-herpes, isifuba somoya kanye nokunye ukungezwani komzimba, i-atopic dermatitis, isifuba, i-eczema kanye ne-bursitis; I-Vitamin B12 ingabuye isetshenziselwe ukuthuthumela, ukucasuka, ukuqwasha, ukulahlekelwa inkumbulo, ukwelashwa kokucindezeleka. Ucwaningo olusha lubonisa ukuthi, ukuntuleka kwe-Vitamin B12 nakho kungabangela ukugula kwengqondo. I-Vitamin B12 njenge-ejenti yokwelapha noma imikhiqizo yezempilo, iphephe kakhulu, izikhathi ezingaphezu kwezinkulungwane ze-RDA I-Vitamin B12 ayitholakali into enobuthi emthanjeni noma emthanjeni.
2. Izicelo maqondana nokudla
I-Vitamin B12 ingakhuthaza ukukhula nokuthuthukiswa kwezinkukhu, imfuyo ikakhulukazi izinkukhu, izilwane ezincane, ukuthuthukisa ukusetshenziswa kwamaprotheni okuphakelayo, futhi ngaleyo ndlela ingasetshenziswa njengezithasiselo zokudla. Ukwelashwa kwamaqanda nokuthosa ngesisombululo sevithamini B12 ukuthuthukisa izinhlanzi zezinto ezinobuthi emanzini njengokubekezelela i-benzene nensimbi enzima nokunciphisa ukufa. Kusukela isigameko "senkomo ehlanya" eYurophu, ukusetshenziswa kwesakhiwo samakhemikhali samavithamini nezinye izithako zokudla okunomsoco esikhundleni se-"MBM" ecacile kunendawo eyengeziwe yokuthuthukiswa. Njengamanje ukukhiqizwa kwe-Vitamin B12 emhlabeni wonke kusetshenziselwa imboni yokudla.
3. Kwezinye izici zesicelo
Emazweni athuthukile, i-Vitamin B12 complex enezinye izinto isetshenziselwa izimonyo; embonini yokudla, i-Vitamin B12 isetshenziswa njenge-ham, isoseji, u-ayisikhilimu, inhlanzi, inyama kanye neminye imibala yokudla. Empilweni yomndeni, isixazululo se-Vitamin B12 sikhangiswa kukhabhoni ecushiwe, ama-zeolite, indwangu engalukiwe noma iphepha okumele lenziwe libe insipho, umuthi wokuxubha, njll; ingasetshenziswa endlini yangasese yokuqeda iphunga, isiqandisi, ukususa iphunga le-sulfide ne-aldehydes; I-Vitamin B12 iyatholakala futhi ekususweni kwe-halogenation yomhlabathi wokuvikela imvelo kanye nokungcola okuvamile kuma-halides angaphezulu kwamanzi.
