Daim ntawv thov
1. L-Methionine yog ib qho tseem ceeb amino acid tseem ceeb rau kev tsim cov protein, ua cov khoom noj khoom haus tseem ceeb hauv cov kab lis kev cai ntawm tes, khoom noj khoom haus, thiab tsiaj pub rau kev loj hlob thiab kev noj qab haus huv.
2. L-Methionine ua raws li lub hauv paus rau cov ntsiab lus tseem ceeb, nrog rau cov antioxidant glutathione, txhawb lub siab noj qab haus huv thiab detoxification txheej txheem, thiab tau kawm txog nws cov anti- laus zog .
3. L-Methionine ua haujlwm raws li tus neeg sawv cev chelating rau cov hlau hnyav xws li cov hlau lead thiab mercury, thiab siv rau hauv kev tshawb fawb txog cov txheej txheem metabolic thiab protein engineering.
Cia thiab ceev faj
1. Khaws L-Methionine nyob rau hauv lub thawv kaw nruj nreem nyob rau hauv qhov chaw txias, qhuav ntawm chav tsev kub (RT) los yog tub yees, tiv thaiv los ntawm lub teeb thiab muaj zog oxidizing cov neeg ua hauj.
2. Khaws L-Methionine nyob rau hauv ib qho chaw inert rau ntev - lub sij hawm stability, raws li L-Methionine yuav hnov mob nrog oxidizers muaj zog thiab yog incompatible nrog muaj zog acids thiab alkalis.
3. Kov L-Methionine siv cov cuab yeej tiv thaiv tus kheej tsim nyog nrog rau cov hnab looj tes thiab tsom iav kev nyab xeeb, thiab zam kev ua pa plua plav los ntawm kev ua haujlwm hauv qhov dej - qhov cua los yog fume hood .
Kev kub ceev teb rau cov dej xau
1. Tshem tawm qhov chaw nchuav, hnav cov cuab yeej tiv thaiv zoo xws li plua plav daim npog qhov ncauj, thiab cheb cov khoom L-Methionine rau hauv cov thawv kaw, cov ntawv sau tsis tsim cov plua plav.
2. Dampen spilled L-Methionine CAS 63-68-3 nrog dej thiab hloov mus rau lub thawv uas tsim nyog, tom qab ntawd ntxuav cov kab mob nrog xab npum thiab dej; tiv thaiv L-Methionine los ntawm kev nkag mus rau hauv cov dej los yog cov dej.
3. Cov neeg ua haujlwm tu L-Methionine spills yuav tsum muab pov tseg pov tseg raws li ib puag ncig kev cai, vim L-Methionine yog nkag tau yooj yim biodegradable thiab tsis xav kom bioaccumulate .
Cov ntaub ntawv kev nyab xeeb
1. L-Methionine feem ntau lees paub tias tsis yog- muaj kev phom sij nrog kev mob toxicity tsawg (LD50 qhov ncauj nas: 36,000 mg/kg), tab sis tej zaum yuav ua rau qhov muag, tawv nqaij, thiab ua pa ua pa thaum muaj plua plav.
2. L-Methionine CAS 63-68-3 yog combustible thiab thaum rhuab mus decomposition emits cov pa phem xws li nitrogen oxides, sulfur oxides, thiab carbon oxides; Cov tshuaj tiv thaiv hnyav tuaj yeem ua rau muaj zog oxidizing cov neeg ua haujlwm.
3. L-Methionine tsis raug cais raws li cov khoom txaus ntshai rau kev thauj mus los, muaj qhov melting point ntawm 284℃(dec.), thiab soluble hauv dej nrog pH ntawm 5-7 (10 g / l ntawm 20 degree).
