Isiqinisekiso sempilo sisilinganiselo samavithamini emzimbeni, kwaye namhlanje siya kuthetha ngeyona nto inomdla kubo. I-Vitamin B12 okanye i-cyanocobalamin yinto echithwa ngamanzi ene-molecule ye-cobalt. Wafunyanwa ngokutsha kwiqela lamavithamini B. Ukungabikho kwe-vitamin B12 kubangela imiphumo emibi kakhulu, eya kuxoxwa ngezantsi.
Indima yeB12 emzimbeni
I-Cyanocobalamin ibandakanyeka kwiprotheni ye-metabolism, eyinxaxheba ekwakheni i-amino acids, kwaye idlala indima ephambili kwinkqubo ye-hematopoiesis-yoko kutheni ukungabikho kwe-vitamin B12, i-anemia idibene.
Ngaphandle kwe-cyanocobalamin, ukuhlanganiswa kweenzyme ezingaphelelanga, ukongeza, i-vitamin inefuthe le-antisclerotic, ngoko isetyenziswe njengonyango lwe- atherosclerosis .
Izizathu zokungabikho kwe vithamini B12
Ukuntuleka kwe-cyanocobalamin kudibaniswa nezizathu eziqhelekileyo (ukungabikho kokutya okuqulethe i-B12) kunye nokugcina (ukungabi nento ebizwa ngokuba yinto yangaphakathi yeKastla, onoxanduva lokufanisa i-vitamin).
Kwimeko yokuqala, iimpawu zokungabikho kwe-vithamini B12 zibonakala ngenxa yokungabikho kokutya kwenyama, intlanzi, ushizi, amaqanda kunye nemveliso yobisi. Kungenxa yokuba izilwanyana zacetyiswa ukuba zijonge ngenyameko kwinqanaba le-cyanocobalamin kwaye lizalise isitokisi salo ngoncedo lwe-vitamin complexes.
Kwimeko yesibini, iimpawu zokungabikho kwe-vitamin B12 zidibaniswa ne-atrophy ye-mucosa yesisu, i-inherited factor, i-helminthic invasions, i-gastritis, isifo sengqondo sesifo , isifo somhlaza wesisu.
Ukulahlekelwa kwe-cyanocobalamin kubonakala njani?
I-Vitamin B12 isebenza ngokubambisana ne-B9 (i-folic acid), kunye nokusilela kwayo, kukho:
- ukuphulwa kwe-hematopoiesis kunye nesakhiwo samaseli egazi abomvu ngokukhethekileyo, abonakaliswe ngokuhlalutya kwegazi;
- I-anemia kwimvelaphi yokuncipha kwinani lamaseli obomvu;
- ukutshatyalaliswa kwenkqubo ye-nervous, ukukhubazeka, ukuguqulwa kwezandla, iminwe;
- isifo esingapheliyo;
- ukuphazamiseka kokulala, ukuxinezeleka, ukucaphuka.
Ukongezelela, ukungabikho kwe-vitamin B12 kunokubonakalisa iimpawu ezinjalo njenge-nasusea, ukulahleka kwesidlo, isifo se-intestinal, izilonda ngolwimi, ukuyeka ukuveliswa kwe-hydrochloric acid ngesisu (achillia).
Imithombo B12
Ubunqwenelekayo be-cyanocobalamin kukungabikho kwayo ngokupheleleyo kwimveliso yezityalo ezivela kumvelaphi, ngoko ke ukungakwazi ukukwazi ukungakwazi ukukwazi ukungakwazi ukukwazi ukufumana ingqinqatshelwa kwiimpawu zokungabikho kwe-vitamin B12
- isibindi kunye neentso zezilwanyana;
- i-octopus, i-herring, i-mackerel;
- yenkomo, imvana;
- ushizi iintlobo ze-cheddar kunye ne-gouda;
- Inkukhu yenkukhu (ngokukodwa i-yolk);
- ubisi, i-yoghurt eyomuncu.
Umgangatho wemihla ngemihla yeB12 kumntu omdala: 2.6-4 μg. Kwakhona, i-vithamini ihlanganiswe emathunjini omntu omntu, kodwa akukho nto ingagciniweyo.
