ISAKHIWO:
Incazelo:
I-Methionine iyi-α-amino acid enefomula yamakhemikhali i-HO2CCH(NH2)CH2CH2SCH3. Le amino acid ebalulekile ihlukaniswa njenge-nonpolar. Le amino-acid ifakwa ikhodi yi-initiation codon AUG ekhombisa indawo yokubhala ikhodi ye-mRNA lapho kuqala khona ukuhunyushwa kube yiprotheni.

Ukusetshenziswa
Ukukhiqizwa kwamakhemikhali aguquguqukayo ahlobene nokunambitheka kokudla okuvela ekuwohlokeni kwe-DL-methionine eStrecker.
Ukwengezwa kwe-methionine ngamanani afanele kulokhu kudla kungalindeleka ukuthi kuthuthukise inani lamaprotheni. Ngokomnotho, i-DL-methionine ingcono kakhulu.
I-amino acid ebalulekile engeyona i-polar enezakhiwo zokuvikela ukucindezeleka kwe-oxidative
I-DL-Methionine ngezinye izikhathi inikezwa njengesengezo ezinjeni; isiza ukuvikela izinja ekulimazeni utshani ngokunciphisa i-pH yomchamo.
I-Methionine ivunyelwe njengesengezo sokudla kwezinkukhu okungokwemvelo ngaphansi kohlelo lwe-organic oluqinisekiswe yi-US.
Ukupakisha Nokuthumela
25KG/Isigubhu.
Kungokwempahla evamile futhi kungathunyelwa ngolwandle nangomoya
Gcina futhi ugcine
Isikhathi sokuphila: Izinyanga ezingama-24 kusukela ngosuku lokwenziwa kwento epakishweni lokuqala elingavulwanga, igcinwe endaweni epholile neyomile kude nokukhanya kwelanga okuqondile, amanzi.
Indawo yokugcina izinto enomoya, Ukomisa okuphansi kwezinga lokushisa, Ihlukaniswe nama-oxidants, ama-acid.
