Xwm:

Cov tshuaj formula: C25H22N2O6

Molecular Luj: 446.46g / mol

-Zoo: Dawb los yog yuav luag dawb crystal lossis hmoov

-Solubility: Fmoc-Gln-OH yog soluble nyob rau hauv ib co organic solvents, xws li dimethyl sulfoxide (DMSO) los yog N, N-dimethylformamide (DMF).

 

Siv:

-Biochemical kev tshawb fawb: Fmoc-Gln-OH tuaj yeem siv los ua cov pab pawg tiv thaiv hauv cov khoom sib txuas rau peptide lossis protein synthesis.

-Drug Development: Fmoc-Gln-OH tuaj yeem siv los ua cov nruab nrab hauv kev sib txuas ntawm cov tshuaj lossis cov tshuaj lom neeg peptides.

 

Txoj Kev Npaj:

Kev npaj ntawm Fmoc-Gln-OH tuaj yeem ua tiav los ntawm cov kauj ruam hauv qab no:

1. Ua ntej, glutamine reacted nrog fluoric anhydride (Fmoc-OSu) kom tau Fmoc-Gln-OH acid fluoride (Fmoc-Gln-OF).

2. Tom qab ntawd, Fmoc-Gln-OF yog reacted nrog pyridine (Py) los yog N, N-dimethylpyrrolidone (DMAP) nyob rau hauv tej yam kev mob los tsim Fmoc-Gln-OH.

 

Cov ntaub ntawv kev nyab xeeb:

-Lub Fmoc-Gln-OH feem ntau muaj kev nyab xeeb nyob rau hauv ib txwm ua haujlwm, tab sis nws tseem tsim nyog ua raws li cov txheej txheem kev nyab xeeb hauv chav kuaj.

- Ua tib zoo tiv thaiv kev sib cuag ntawm daim tawv nqaij, ob lub qhov muag los yog mucous daim nyias nyias, thiab tsis txhob nqus los yog noj.

-Thaum siv, koj tuaj yeem hnav cov khoom tiv thaiv tus kheej tsim nyog, xws li cov hnab looj tes kuaj, tsom iav kev nyab xeeb thiab cov khaub ncaws hauv chav kuaj.

-Thaum muaj kev huam yuaj lossis tsis xis nyob, nrhiav kev pab kho mob raws sij hawm thiab nqa cov ncauj lus kom ntxaws txog tshuaj rau kev siv.
