Qhov sib txawv tseem ceeb ntawm DL methionine thiab L methionine yog tias DL methionine yog cov sib xyaw ua ke ntawm D thiab L enantiomers ntawm methionine whereas L methionine yog L enantiomer ntawm methionine.
Methionine yog ib qho tseem ceeb amino acid rau tib neeg. Nws plays lub luag haujlwm tseem ceeb hauv cov metabolism thiab kev noj qab haus huv; nws kuj yog ib feem ntawm angiogenesis (kev loj hlob ntawm cov hlab ntsha tshiab). Tsis tas li ntawd, cov tshuaj ntawm methionine tuaj yeem pab cov neeg raug kev txom nyem los ntawm tooj liab lom. Lub codon uas encodes no amino acid yog AUG.
DL Methionine yog dab tsi?
DL methionine yog sib xyaw ntawm ob enantiomers D-methionine thiab L-methionine. Yog li ntawd, nws muaj ib tug sib tov ntawm ob hom ntawm tib lub compound. Peb hu qhov no "racemethionine" vim hais tias ib tug sib tov ntawm D thiab L enantiomers yog hu ua ib tug racemic sib tov. Nws zoo nkaus li dawb crystalline hmoov los yog me me flakes. Tsis tas li ntawd, nws dissolves nyob rau hauv dej sparingly thiab yog me ntsis soluble nyob rau hauv ethanol.
DL methionine yog siv los ua kev noj haus ntxiv. Nws muaj lipotropic kev ua haujlwm. Tsis tas li ntawd, qee zaum nws tau muab rau dev vim nws tuaj yeem pab txo cov pob zeb hauv dev.
L Methionine yog dab tsi?
L methionine yog L enantiomer ntawm cov amino acid methionine. Feem ntau, L methionine yog qhov sib xyaw peb hu ua "methionine". Nws yog thawj zaug pom los ntawm American kws tshawb fawb John Howard Mueller (1921). Tsis tas li ntawd, nws yog ib qho tseem ceeb amino acid hauv peb lub cev uas tseem ceeb rau kev tsim cov proteins. Peb tuaj yeem pom cov amino acid no hauv qee yam khoom noj xws li nqaij, ntses thiab khoom noj siv mis.

Ntxiv mus, cov amino acid no tseem ceeb heev hauv kev loj hlob ntawm cov hlab ntsha tshiab. Tsis tas li ntawd, nws yog ib qho tseem ceeb rau kev kho cov ntaub so ntswg. Tsis tas li ntawd, nws yog ib qho sulfur-muaj amino acid thiab koom nrog ntau cov txheej txheem detoxifying hauv peb lub cev, xws li tiv thaiv cov hlwb los ntawm cov pa phem. Tsis tas li ntawd, nws slows cell aging thiab yog qhov tseem ceeb rau kev nqus ntawm selenium thiab zinc.
Qhov txawv ntawm DL Methionine thiab L Methionine yog dab tsi?
DL methionine yog sib xyaw ntawm ob enantiomers D-methionine thiab L-methionine thaum L methionine yog L enantiomer ntawm amino acid methionine. Yog li, qhov sib txawv tseem ceeb ntawm DL methionine thiab L methionine yog tias DL methionine yog cov sib xyaw ua ke ntawm D thiab L enantiomers ntawm methionine whereas L methionine yog L enantiomer ntawm methionine.
Thaum xav txog lawv cov kev siv, DL methionine yog siv los ua kev noj haus ntxiv thaum L methionine tseem ceeb rau kev loj hlob ntawm cov hlab ntsha tshiab, qeeb cell aging, thiab yog qhov tseem ceeb rau kev nqus ntawm selenium thiab zinc. Yog li, qhov no kuj yog qhov sib txawv tseem ceeb ntawm DL methionine thiab L methionine.
Summary – DL Methionine vs L Methionine
Methionine yog ib qho tseem ceeb amino acid uas tshwm sim hauv ob hom enantiomers li D-methionine thiab L-methionine. Qhov sib txawv tseem ceeb ntawm DL methionine thiab L methionine yog tias DL methionine yog cov sib xyaw ua ke ntawm D thiab L enantiomers ntawm methionine whereas L methionine yog L enantiomer ntawm methionine.
