L-Methionine yog dab tsi?
L-Methionine yog sulfur-muaj qhov tseem ceeb L-amino acid uas tseem ceeb hauv ntau lub cev ua haujlwm. Methionine yog ib qho khoom noj khoom haus tsis tseem ceeb amino acid uas xav tau rau kev loj hlob thiab kev loj hlob ntawm tib neeg, lwm yam tsiaj txhu, thiab hom avian. Ntxiv nrog rau kev ua lub substrate rau cov protein synthesis, nws yog ib qho nruab nrab ntawm cov tshuaj tiv thaiv transmethylation, ua cov pab pawg neeg loj methyl pub.
Methionine yog hom amino acid tseem ceeb hauv cov tsiaj noj. Ntxiv methionine yog ib qho tseem ceeb ntxiv hauv cov tsiaj pub, uas tuaj yeem pab tsiaj loj hlob sai hauv lub sijhawm luv luv thiab txuag txog 40% ntawm cov khoom noj. Tshwj xeeb tshaj yog nyob rau hauv pub nqaij qaib pub, methionine yog thawj limiting amino acid. Methionine deficiency hauv cov tsiaj txhu tuaj yeem ua rau kev loj hlob qeeb, poob phaus, txo lub raum ua haujlwm, cov leeg nqaij atrophy, thiab degeneration ntawm plaub. Hauv kev lag luam pub, qhov kev thov rau methionine yog qhov loj heev, tshwj xeeb tshaj yog rau ntau yam amino acids hauv cov khoom noj khoom haus additives, methionine account rau 60%, lysine account rau 30%, thiab lwm yam amino acids suav txog li 10%.
Pub Additives
L-Methionine feem ntau yog siv los ua zaub mov noj thiab yog ib qho tseem ceeb amino acids hauv kev loj hlob ntawm cov tsiaj, uas yog "skeleton" amino acid nyob rau hauv protein biosynthesis thiab lub ntsiab pub ntawm methyl nyob rau hauv cov tsiaj lub cev. L-Methionine plays lub luag haujlwm hauv cov txheej txheem ntawm synthesis ntawm choline los ntawm adrenal hormone thiab fatty siab phospholipids thaum lub sij hawm tus txheej txheem ntawm metabolism ntawm tus tsiaj nyob rau hauv vivo. Tsis muaj L-Methioninein cov tsiaj nyeg thiab nqaij qaib yuav ua rau kev loj hlob tsis zoo, poob phaus, lub siab thiab lub raum ua haujlwm poob qis, cov leeg nqaij atrophy, fur deterioration, thiab lwm yam.
ML-Methionine yog sulfur amino acid thiab qhov thib ob txwv cov amino acids tseem ceeb rau npua. Kev siv piv ntawm cov protein pub tuaj yeem txhim kho tau zoo yog tias lysine thiab L-Methioninewere ntxiv rau hauv cov khoom noj kom tsim nyog. Yog li cov lysine thiab L-Methionineare hu ua enhancer rau protein pub. Pub additives; Raws li cov khoom thiab cysteine ob leeg koom nrog sulfur-muaj amino acids, yog li muaj ntau ntawm lawv muaj nyob rau hauv cov tsiaj proteins. Txawm li cas los xij, nws belongs rau txwv cov amino acids hauv cov nroj tsuag proteins xws li oats, rye, mov, pob kws, nplej, txiv laum huab xeeb, taum pauv, qos yaj ywm, spinach thiab lwm yam zaub mov thiab cov ntsiab lus tsawg dua li tsiaj proteins. saum cov zaub mov los txhim kho qhov sib npaug ntawm cov amino acids. Yav dhau los, sulfur-muaj cov amino acids tau xav tias tsuas yog tsim nyog rau cov tsis muaj ruminants. Tab sis tam sim no qhov kev sim tau ua pov thawj tias nws muaj feem xyuam rau cov neeg tsis muaj ruminants. Nws yog tsim nyog rau nqaij qaib thiab npua noj. Ntawm kev kho mob, nws tuaj yeem siv rau infusion ua ke nrog lwm cov amino acids. Kuj tseem siv los ua kab lis kev cai nruab nrab thaum fermentation.
Kev siv L-methionine
Nws yog dav siv raws li pub additives los txhim kho kev noj zaub mov zoo, txhim kho kev siv cov protein ib txwm thiab txhawb cov tsiaj loj hlob. Xws li DL-methionine tuaj yeem ua rau cov qe qe ntau ntxiv ntawm cov nqaij qaib, npua ua rau qhov hnyav nce, ntau cov mis nyuj thiab lwm yam. Nyob rau tib lub sijhawm, nws tuaj yeem siv los ua cov khoom noj khoom haus. Rau kev tshawb fawb biochemical thiab khoom noj khoom haus, thiab raws li kev kho mob rau kev mob ntsws, mob siab cirrhosis thiab fatty siab.
