Taw qhia
FMOC-L-leucine yog ib qho organic compound.
Zoo:
FMOC-L-leucine yog dawb mus rau yellowish crystal nrog muaj zog hygroscopicity. Nws yog soluble hauv cov kuab tshuaj organic xws li ethanol, methanol, thiab dimethylformamide, thiab lwm yam.
Siv:
FMOC-L-leucine feem ntau yog siv rau peptide synthesis thiab polymer synthesis hauv solid-thesis synthesis. Raws li pab pawg tiv thaiv hauv peptide synthesis, nws tiv thaiv kev tsis sib haum xeeb ntawm lwm cov amino acids, ua rau cov txheej txheem synthesis ntau qhov tshwj xeeb thiab siab purity.
Txoj kev:
FMOC-L-leucine tuaj yeem npaj los ntawm condensation ntawm leucine nrog 9-fluhantadone. N-acetone thiab leucine tau ntxiv rau hauv lub cev hnyav, thiab tom qab ntawd 9-fluhantadone tau maj mam ntxiv dropwise, thiab thaum kawg crystallization tau nqa tawm kom tau txais cov khoom.
Cov ntaub ntawv kev nyab xeeb:
FMOC-L-leucine feem ntau tsis muaj tshuaj lom rau tib neeg thiab ib puag ncig. Raws li cov organic compound, nws yuav muaj kev cuam tshuam rau ntawm daim tawv nqaij, ob lub qhov muag, thiab mucous daim nyias nyias. Kev sib cuag nrog daim tawv nqaij ntev yuav tsum tau zam thaum siv, thiab yuav tsum tau saib xyuas kom tsis txhob sib cuag nrog lub qhov muag thiab nqus tau nws cov plua plav.
