Kev piav qhia:
Methionine yog ib qho α-amino acid nrog cov mis tshuaj HO2CCH(NH2)CH2CH2SCH3. Cov amino acid tseem ceeb no yog cais ua nonpolar. Cov amino-acid no yog coded los ntawm initiation codon AUG uas qhia txog mRNA lub cheeb tsam coding qhov twg txhais lus rau hauv protein pib.

Kev Siv
Kev tsim cov tshuaj volatile uas cuam tshuam nrog cov saj ntawm cov khoom noj los ntawm Strecker degradation ntawm DL-methionine.
Yog tias ntxiv methionine rau hauv cov khoom noj no kom txaus, ces yuav ua rau cov protein muaj nqis ntxiv. Yog xav kom muaj DL-methionine ces zoo dua.
Ib qho tseem ceeb amino acid nonpolar nrog cov khoom tiv thaiv kev ntxhov siab oxidative
DL-Methionine qee zaum muab ua ib qho tshuaj ntxiv rau dev; nws pab tiv thaiv dev kom tsis txhob ua puas rau cov nyom los ntawm kev txo cov pH ntawm cov zis.
Methionine raug tso cai ua ib qho ntxiv rau cov khoom noj qaib organic raws li Tebchaws Meskas cov kev pab cuam organic tau ntawv pov thawj.
Ntim thiab Xa Khoom
25KG / Nruas.
Yog cov khoom siv dav dav thiab tuaj yeem xa los ntawm dej hiav txwv thiab huab cua
Khaws cia thiab khaws cia
Lub neej txee: 24 lub hlis txij li hnub tsim khoom hauv cov ntim khoom tsis tau qhib khaws cia rau hauv qhov chaw txias thiab qhuav kom tsis txhob raug tshav ntuj ncaj qha, dej.
Lub tsev rau khoom muaj cua nkag, ziab kom qhuav kub tsawg, Sib cais ntawm cov tshuaj oxidants, cov kua qaub.
