Mawu Oyamba

FMOC-O-tert-butyl-L-threonine ndi pawiri ndi zotsatirazi katundu:

 

Maonekedwe: Makristalo oyera kapena osayera.

Solubility: sungunuka mu zosungunulira organic, monga dimethyl sulfoxide, N, N-dimethylformamide, etc., insoluble m'madzi.

 

Kugwiritsa ntchito FMOC-O-tert-butyl-L-threonine:

Kaphatikizidwe ka peptide: monga gulu loteteza, limagwiritsidwa ntchito popanga ma peptide ndikusinthana kwa ion mkati mwawo.

Kafukufuku wam'chilengedwe: kaphatikizidwe ndi kuphunzira ma peptides achilengedwe ndi mapuloteni.

 

Njira yokonzekera FMOC-O-tert-butyl-L-threonine:

FMOC-O-tert-butyl-L-threonine ikhoza kupangidwa ndi izi:

L-threonine imayendetsedwa ndi FMOC-O-tert-butyl-N-hydroimide kupanga FMOC-O-tert-butyl-L-threonine-N-agar powder ester.

FMOC-O-tert-butyl-L-threonine-N-agar powder ester anali hydrolyzed kuti apeze FMOC-O-tert-butyl-L-threonine.

 

Zambiri zachitetezo cha FMOC-O-tert-butyl-L-threonine:

Pewani kukhudzana mwachindunji ndi khungu ndi maso, kuyabwa ndi ziwengo zingachitike.

Chonde gwirani ntchito pamalo olowera mpweya wabwino ndipo pewani kutulutsa nthunzi kapena fumbi.

Iyenera kukhala yosindikizidwa mwamphamvu posunga ndikupewa kukhudzana ndi okosijeni.

Gwiritsani ntchito zodzitetezera zanu monga magolovesi oteteza, magalasi, ndi malaya a labu mukamagwiritsa ntchito.
