Taw qhia
L-2- (tert-butoxycarbonylamino) butyric acid yog ib qho amino acid derivative. Nws yog xim tsis muaj xim nrog cov amino thiab carboxyl ua haujlwm pab pawg. Soluble nyob rau hauv dej ntawm chav tsev kub.
Nws kuj tseem siv los kawm txog cov txheej txheem lom neeg xws li folding, adsorption, thiab enzymatic cov tshuaj tiv thaiv ntawm cov protein.
Txoj kev npaj L-2-(tert-butoxycarbonylamino) butyric acid yog raws li nram no: 2-aminobutyric acid yog reacted nrog tert-butoxycarbonyl chloride los ua L-2-(tert-butoxycarbonyl amino)butyrate. Tom ntej no, ester yog hydrolyzed nrog cov kua qaub kom tau L-2-(tert-butoxycarbonylamino)butyric acid.
Cov ntaub ntawv kev nyab xeeb: L-2-(tert-butoxycarbonylaminobutyric acid) kuj muaj kev nyab xeeb nyob rau hauv ib txwm ua haujlwm, tab sis tseem yuav tsum tau ceev faj hauv qab no: tsis txhob sib cuag nrog lub qhov muag, tawv nqaij thiab khaub ncaws; Tsis txhob nqus los yog nqus tau; siv cov cuab yeej ua pa hauv chaw ua haujlwm tsim nyog; Hnav cov khoom tiv thaiv tus kheej tsim nyog xws li hnab looj tes, tsom iav, thiab khaub ncaws tiv thaiv.
