Vitamin B12 tseem hu ua Hydroxycobalamin

Hydroxycobalamin (ohcbl, los yog B12a) yog ib hom ntawm vitamin B12, los yog ib qho ntawm cov vitamin B12 chav kawm. Nws yog ib tug tswv cuab ntawm pawg cobalamine. Ntau tus kab mob uas tsim cov vitamins ua lag luam tsim cov vitamin B12 hauv daim ntawv ntawm hydroxycobalamin. Hydroxycobalamin yog xim liab. Vitamin B12 nyob rau hauv tib neeg lub cev tsis nquag muaj nyob rau hauv daim ntawv ntawm hydroxycobalamin. Txawm li cas los xij, hauv tib neeg, hydroxycobalamin tau yooj yim hloov mus rau hauv daim ntawv coenzyme tseem ceeb ntawm Vitamin B12.

Muaj nuj nqi

Tam sim no, muaj plaub hom vitamin B12 hauv ntiaj teb API kev ua lag luam. Lawv yog hydroxycobalamin, Mecobalamin, cyanobalamin thiab cobalamin adenosine. Qhov no yog vim lub hauv paus ion hauv B12 molecule muaj cov pab pawg ua haujlwm sib txawv, yog li nws raug hu ua cov npe sib txawv. Hydroxycobalamin hu ua hydroxycobalamin vim tias lub hauv paus ion ntawm B12 txuas nrog hydroxyl pawg. Ntawm cov plaub B12 molecules, hydroxycobalamin muaj cov dej solubility zoo tshaj plaws thiab qeeb metabolism hauv cov zis, uas tseem hu ua cobalamin ua haujlwm ntev. Txawm hais tias tus nqi nqus tsis zoo piv rau cov cyanocobalamin thiab Mecobalamin, nws cov concentration hauv lub qhov muag yog siab heev, uas tuaj yeem txo qhov pom kev qaug zog thiab txhawb nqa lub paj hlwb. Yog li, nws muaj qee yam kev kho mob ntawm amblyopia tshwm sim los ntawm kev lom. Tsis tas li ntawd, hydroxycobalamin tuaj yeem ua ke sai sai nrog dawb cyanide los tsim cov tshuaj tsis muaj tshuaj lom cyanobalamin hauv cov tshuaj aqueous, yog li nws cov nyhuv kho mob yog tshuaj tua kab mob ntawm cyanide lom.
