1.Methylcobalamin yog siv los kho cov vitamin B12 tsis txaus. Vitamin B12 tseem ceeb rau lub hlwb thiab cov hlab ntsha, thiab rau kev tsim cov qe ntshav liab.

2.Methylcobalamin qee zaum siv rau cov neeg muaj ntshav qab zib mellitus, ntshav qab zib, thiab lwm yam mob.

3.Methylcobalamin kuj tseem siv tau rau cov hom phiaj uas tsis tau teev tseg hauv phau ntawv qhia tshuaj no.

Lub luag haujlwm tseem ceeb ntawm Methylcobalamin yog dab tsi?

Lub luag haujlwm tseem ceeb:

Methylcobalamin

1. Txhawb kev hloov methyl

2. Txhawb txoj kev loj hlob thiab kev loj hlob ntawm cov qe ntshav liab, ua kom lub cev hematopoietic muaj nuj nqi, tiv thaiv pernicious anemia; tswj kev noj qab haus huv ntawm lub paj hlwb

3. Nyob rau hauv daim ntawv ntawm coenzyme, nws muaj peev xwm nce qhov kev siv ntawm folic acid thiab txhawb lub metabolism ntawm carbohydrate, rog thiab protein.

4. Nws muaj kev ua haujlwm ntawm activating amino acids thiab txhawb kev biosynthesis ntawm nucleic acid, uas tuaj yeem txhawb nqa cov synthesis ntawm cov protein. Nws ua lub luag haujlwm tseem ceeb hauv kev loj hlob thiab kev loj hlob ntawm cov menyuam mos thiab menyuam yaus.

5. Metabolize fatty acids, kom cov rog, carbohydrates thiab protein yog siv los ntawm lub cev

6. Tshem tawm kev chim siab, mloog zoo, txhim khu kev nco thiab kev sib npaug

7. Nws yog ib qho tseem ceeb ntawm cov vitamin rau kev noj qab haus huv ntawm lub paj hlwb thiab koom nrog kev tsim cov lipoprotein hauv cov ntaub so ntswg.

Ib qho yog txhawm rau txhim kho qhov kev siv ntawm folic acid, synthesize methionine (synthesized los ntawm homocysteine) thiab choline ua ke nrog folic acid, thiab synthesize cyanocobalamin precursors xws li methylcobalamin thiab coenzyme thaum lub sij hawm tsim cov purines thiab pyrimidines B12, koom nrog cov txheej txheem ntawm ntau cov ntsiab lus tseem ceeb. Thaum vitamin B12 tsis txaus, kev ua haujlwm ntawm kev hloov cov methyl pawg los ntawm methyltetrahydrofolate txo qis, ua rau cov tshuaj folic acid ua rau tsis muaj folic acid.

Qhov thib ob yog tswj cov metabolism thiab ua haujlwm ntawm cov paj hlwb myelin sheath. Thaum tsis muaj vitamin B12, nws tuaj yeem ua rau muaj kev puas tsuaj rau lub paj hlwb, tus txha caj qaum degeneration, thiab tuaj yeem ua rau muaj kev puas siab puas ntsws loj. Vitamin B12 deficiency tuaj yeem ua rau peripheral neuritis. Qhov tshwm sim thaum ntxov ntawm tus me nyuam qhov tsis txaus vitamin B12 yog qhov txawv txav ntawm lub siab, kev hais lus qeeb, tsis teb, thiab thaum kawg anemia.

Qhov thib peb yog los txhawb txoj kev loj hlob thiab loj hlob ntawm cov qe ntshav liab. Methylmalonyl-CoA hloov mus rau succinyl-CoA, uas koom nrog hauv lub voj voog tricarboxylic acid, thiab succinyl-CoA muaj feem xyuam rau kev sib txuas ntawm heme.

Plaub, vitamin B12 kuj koom nrog hauv kev sib txuas ntawm deoxynucleic acid (DNA), cov metabolism hauv cov rog, carbohydrates thiab cov protein, thiab ua kom cov synthesis ntawm nucleic acids thiab proteins.

Tsis muaj ntxiv:

Tsis muaj tsos mob

Tsis muaj vitamin B12 ua rau muaj kev tsis txaus ntseeg (3 daim duab)

⒈Pernicious anemia (cov qe ntshav liab tsis txaus)

⒉ Kev coj khaub ncaws tsis xwm yeem

⒊ Qhov muag daj thiab tawv nqaij, hauv zos (me) liab thiab o (tsis mob lossis khaus) ntawm daim tawv nqaij, nrog rau molting;

⒋ xeev siab, tsis qab los noj mov, poob phaus

⒌Dawb daim di ncauj, tus nplaig thiab cov pos hniav, los ntshav cov pos hniav
