Taw qhia

Boc-Asp-OBzl (Boc-Asp-OBzl) yog ib qho chaw uas muaj cov khoom nram qab no:

 

1. Cov tsos: Dawb crystalline khoom.

2. Cov mis mos molecular: C24H27N3O7.

3. Molecular Luj: 469.49g/mol.

4. Melting point: txog 130-134 ° C.

 

Boc-Asp-OBzl yog dav siv hauv biochemistry thiab hluavtaws organic chemistry, feem ntau siv rau hauv kev sib txuas ntawm peptides, proteins thiab tshuaj, nrog rau kev siv hauv qab no:

 

1. Peptide synthesis: Raws li ib feem ntawm pab pawg tiv thaiv (Boc tiv thaiv pawg), cov amino pawg hauv aspartic acid amino acid tuaj yeem tiv thaiv.

2. Kev tshawb fawb tshuaj: rau kev sib txuas ntawm cov tshuaj peptide nrog cov tshuaj tiv thaiv kab mob, tiv thaiv qog thiab tiv thaiv kab mob.

3. Cov tshuaj tiv thaiv Enzyme: Boc-Asp-OBzl tuaj yeem siv rau enzyme catalyzed cov tshuaj tiv thaiv substrate.

 

Txoj kev npaj Boc-Asp-OBzl yog raws li nram no:

 

Aspartic acid thiab benzoyl chloride yog esterified los ua tert-butoxycarbonyl-aspartic acid benzyl ester (Boc-Asp-OMe), uas yog tom qab reacted nrog sodium hexoxide kom tau ib tug intermediate nyob rau hauv daim ntawv ntawm N-hexanoate. Thaum kawg, nws tau txais cov tshuaj tiv thaiv benzoylation los tsim Boc-Asp-OBzl.

 

Ua tib zoo saib cov ntaub ntawv kev nyab xeeb hauv qab no thaum siv Boc-Asp-OBzl:

 

1. Qhov sib xyaw ua ke tuaj yeem ua rau khaus thiab ua xua rau tib neeg lub cev, thiab kev sib cuag ncaj qha rau ntawm daim tawv nqaij thiab qhov muag yuav tsum zam.

2. Kev tiv thaiv tus kheej tsim nyog yuav tsum tau ua thaum lub sijhawm ua haujlwm, xws li hnav hnab looj tes thiab tsom iav.

3. Khaws kom qhuav thiab kaw thaum khaws cia, thiab kom deb ntawm hluav taws thiab oxidant.

4. Thaum siv thiab tuav Boc-Asp-OBzl, thov ua raws li cov txheej txheem kev ua haujlwm raug cai thiab kev ua haujlwm zoo.

 

Thov nco ntsoov tias thaum siv Boc-Asp-OBzl lossis lwm yam tshuaj, koj yuav tsum ua raws li cov lus qhia txog kev nyab xeeb, thiab ua raws li kev tiv thaiv tus kheej thiab kev ntsuas kev pheej hmoo raws li qhov xwm txheej tiag tiag.
