Taw qhia

Fmoc-L-isoleucine yog ib tug derivative ntawm ib tug natural amino acid nrog rau cov nram qab no zog:

 

Cov tsos mob: feem ntau yog dawb los yog tawm-dawb crystalline hmoov.

 

Solubility: Fmoc-L-isoleucine yog soluble hauv cov kuab tshuaj organic xws li dimethyl sulfoxide lossis dimethylformamide, insoluble hauv dej.

 

Kev Siv: Fmoc-L-isoleucine yog dav siv nyob rau hauv cov khoom-theem synthesis thiab tuaj yeem siv rau peptide synthesis thiab protein ntau spectrometry.

 

Txoj kev: Kev npaj ntawm Fmoc-L-isoleucine feem ntau yog ua los ntawm cov txheej txheem tshuaj synthesis, qhov twg cov kauj ruam tseem ceeb suav nrog kev qhia txog Fmoc tiv thaiv pawg rau cov amino pawg L-isoleucine.

 

Cov Lus Qhia Txog Kev Nyab Xeeb: Fmoc-L-isoleucine tsis muaj tshuaj lom thiab muaj kev phom sij raws li kev siv ib txwm muaj. Zoo li feem ntau cov tshuaj tua kab mob, yuav tsum tau saib xyuas kom tsis txhob muaj kev sib cuag nrog daim tawv nqaij thiab nqus tau pa. Hnav cov khoom tiv thaiv tsim nyog, xws li cov hnab looj tes (lab) thiab tsom iav tiv thaiv, thaum siv lawv.
