Vitamin B12 (Mecobalamin) CAS: 13422-55-4 Chaw tsim tshuaj paus

Methylcobalamin yog ib hom endogenous coenzyme B12, koom nrog hauv ib lub voj voog carbon unit, ua lub luag haujlwm tseem ceeb hauv kev tsim cov txheej txheem methionine homocysteine ​​​​methyl hloov pauv. Ib qho ntawm cov qauv biologically active ntawm vitamin B12; txawv tsuas yog los ntawm kev hloov pauv ntawm methyl rau pawg cyano. Coenzyme xav tau hauv biosynthesis ntawm methionine. Vitamin (hematopoietic). Nws yog siv rau kev kho mob ntawm cov kab mob ntawm lub paj hlwb, txo qhov mob thiab loog, ua kom sai sai txo qhov mob, txhim kho qhov mob los ntawm cervical spondylosis, kho qhov lag ntseg tam sim ntawd, thiab lwm yam. Mecobalamin yog siv rau kev kho mob peripheral paj hlwb tsis zoo, piv nrog lwm cov vitamin B12 npaj, muaj kev hloov pauv zoo ntawm cov ntaub so ntswg paj hlwb, los ntawm kev hloov pauv methyl, tuaj yeem txhawb nucleic acid, protein lipid metabolism, kho cov ntaub so ntswg paj hlwb puas tsuaj. Hauv homocysteine ​​​​​​tsim qe ammonia acid txheej txheem, nws ua lub luag haujlwm ntawm coenzyme, tshwj xeeb tshaj yog los ntawm deoxyuridine synthesis ntawm thymidine, txhawb DNA thiab RNA synthesis ntawm kev koom tes. Tsis tas li ntawd, hauv kev sim ntawm cov hlwb glial, cov tshuaj tuaj yeem txhim kho methionine synthase kev ua ub no thiab txhawb kev tsim cov myelin lipids lecithin. Txhim kho cov metabolism ntawm cov hlab ntsha, tuaj yeem txhawb nqa axis cable thiab protein synthesis, ua rau tus nqi xa khoom ntawm cov protein pob txha ze rau qhov qub, tswj cov haujlwm axonal.
