Taw qhia
N-(α)-Boc-L-aspartyl yog ib qho amino acid derivative, uas muaj cov khoom nram qab no:
Cov tsos mob: dawb mus rau yellowish crystalline hmoov;
Solubility: soluble nyob rau hauv cov organic solvents, xws li dimethylformamide (DMF) thiab methanol;
Kev ruaj ntseg: ruaj khov nyob rau hauv ib puag ncig qhuav, tab sis raug rau cov dej noo nyob rau hauv cov huab cua ntub, yuav tsum zam kom tsis txhob muaj cov av noo ntev ntev.
Nws cov ntawv thov tseem ceeb suav nrog:
Peptide synthesis: raws li qhov nruab nrab ntawm cov synthesis ntawm polypeptides, nws tuaj yeem siv los tsim peptide saw kev loj hlob;
Kev tshawb fawb lom neeg: ua ib qho tseem ceeb rau kev sib txuas ntawm cov protein thiab kev tshawb fawb hauv chav kuaj.
Txoj kev npaj ntawm N-(α)-Boc-L-aspartoyl acid feem ntau ua tiav los ntawm kev ua haujlwm L-aspartyl acid nrog Boc-tiv thaiv reagent.
Cov ntaub ntawv kev nyab xeeb: N-(α)-Boc-L-aspartoyl acid feem ntau suav hais tias yog cov khoom sib xyaw nrog cov tshuaj lom neeg tsawg. Raws li cov tshuaj reagent, cov txheej txheem kev ua haujlwm nyab xeeb hauv chav kuaj tshuaj yuav tsum tau ua raws li thaum tuav thiab siv lawv. Kev sib cuag ntawm daim tawv nqaij thiab nqus cov plua plav yuav tsum zam. Cov cuab yeej tiv thaiv tus kheej tsim nyog xws li hnab looj tes, tsom iav, thiab lub ntsej muag tiv thaiv yuav tsum hnav thaum siv. Nyob rau hauv rooj plaub ntawm kev sib chwv los yog kev noj, nrhiav kev kho mob tam sim ntawd.
