I-DL-Methionine/iMethionine/i-CAS: 59-51-8
Inkcazo emfutshane:
Igama leMveliso: DL-Methionine/Methionine
I-CAS: 59-51-8
Uhlobo: ZA-Y
MF:C5H11NO2S
MW:149.21
ULWAKHIWO:
Inkcazo:
I-Methionine yi-α-amino acid enefomyula yekhemikhali i-HO2CCH(NH2)CH2CH2SCH3. Le amino acid ibalulekileyo ihlelwa njenge-nonpolar. Le amino-acid ikhowudiwa yi-initiation codon AUG ebonisa indawo yekhowudi ye-mRNA apho ukuguqulelwa kwiproteni kuqala khona.
Inkcazo:

Ukusetyenziswa
Ukuveliswa kweekhompawundi eziguquguqukayo ezinxulumene nencasa yokutya ngenxa yokonakala kwe-DL-methionine eStrecker.
Ukongezwa kwe-methionine ngobuninzi obufanelekileyo kwezi zinto zokutya kunokulindeleka ukuba kuphucule ixabiso leproteni. Ngokwezoqoqosho, i-DL-methionine ingcono.
I-amino acid ebalulekileyo engeyiyo i-polar eneempawu zokukhusela uxinzelelo lwe-oxidative
Ngamanye amaxesha i-DL-Methionine inikwa izinja njengesongezelelo; inceda izinja zingalimazi ingca ngokunciphisa i-pH yomchamo.
I-Methionine ivumelekile njengesongezelelo kwisondlo seenkukhu zendalo phantsi kwenkqubo ye-organic eqinisekisiweyo yase-US.
Ukupakishwa kunye nokuthunyelwa
25KG/Idrama.
Yeyokwempahla eqhelekileyo kwaye inokuhanjiswa ngolwandle nangomoya
Gcina kwaye ugcine
Ixesha lokuphelelwa: Iinyanga ezingama-24 ukususela kumhla wokwenziwa kwayo kwiphakheji yokuqala engavulwanga igcinwe kwindawo epholileyo neyomileyo kude nelanga elithe ngqo, amanzi.
Indawo yokugcina umoya, Ukomisa kubushushu obuphantsi, Yahlulwe kwii-oxidants, ii-asidi.
