Taw qhia
Boc-L-glutamic acid yog cov organic compound nrog cov tshuaj npe tert-butoxycarbonyl-L-glutamic acid. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm Boc-L-glutamic acid:
Zoo:
Boc-L-glutamic acid yog dawb crystalline khoom uas yog soluble nyob rau hauv ib co organic solvents xws li methanol, ethanol, thiab dimethyl sulfoxide. Nws yog qhov ruaj khov ntawm chav tsev kub, tab sis tuaj yeem decompose ntawm qhov kub thiab txias.
Siv:
Boc-L-glutamic acid yog cov tshuaj tiv thaiv uas feem ntau siv hauv peptide synthesis cov tshuaj tiv thaiv hauv cov organic synthesis. Nws tiv thaiv cov carboxyl pawg ntawm glutamic acid, yog li tiv thaiv nws los ntawm sab hauv cov tshuaj tiv thaiv. Thaum cov tshuaj tiv thaiv tiav, Boc tiv thaiv pab pawg tuaj yeem raug tshem tawm los ntawm cov tshuaj tiv thaiv acid lossis hydrogenation, uas ua rau tsim cov peptide ntawm kev txaus siab.
Txoj kev:
Boc-L-glutamic acid tuaj yeem tau txais los ntawm kev ua haujlwm L-glutamic acid nrog tert-butylhydroxycarbamoyl (BOC-ON). Cov tshuaj tiv thaiv tshwm sim hauv cov kuab tshuaj organic, feem ntau ntawm qhov kub thiab txias, thiab yog catalyzed los ntawm lub hauv paus.
Cov ntaub ntawv kev nyab xeeb:
Kev siv Boc-L-glutamate yuav tsum ua raws li kev soj ntsuam kev nyab xeeb. Nws cov plua plav tuaj yeem ua rau lub ntsws ua pa, qhov muag thiab tawv nqaij, thiab cov khoom siv tiv thaiv tus kheej xws li lub tshuab ua pa, tsom iav thiab hnab looj tes yuav tsum hnav thaum tuav. Nws yuav tsum tau muab cia rau hauv qhov chaw qhuav, txias kom tsis txhob muaj oxidants thiab muaj zog acids thiab bases. Nyob rau hauv cov ntaub ntawv ntawm kev huam yuaj los yog kev sib cuag nrog daim tawv nqaij, nrhiav kev kho mob los yog nrog ib tug kws tshaj lij tam sim ntawd.
