Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Izimpawu Eziyingozi Xi - Irritant
Amakhodi Engozi 36/37/38 - Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba.
Incazelo Yokuphepha I-S24/25 - Gwema ukuthintana nesikhumba namehlo.
S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu ​​kanye nokuvikela iso/ubuso.
S27 – Khumula ngokushesha zonke izingubo ezingcolile.
S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha.

Isingeniso

I-Fmoc-Gln-OH(Fmoc-Gln-OH) iphuma ku-amino acid enezici ezilandelayo:

 

Imvelo:

-Ifomula yamakhemikhali: C25H22N2O6

Isisindo samangqamuzana: 446.46g/mol

-Ukubukeka: Ikristalu emhlophe noma ecishe ibe mhlophe noma impushana

-Ukunyibilika: I-Fmoc-Gln-OH iyancibilika kwezinye izinyibilikisi zemvelo, njenge-dimethyl sulfoxide (DMSO) noma i-N,N-dimethylformamide (DMF).

 

Sebenzisa:

-Ucwaningo lwamakhemikhali ezinto eziphilayo: I-Fmoc-Gln-OH ingasetshenziswa njengeqembu elivikelayo ekuhlanganiseni kwesigaba esiqinile se-peptide noma i-protein synthesis.

-Ukuthuthukiswa Kwezidakamizwa: I-Fmoc-Gln-OH ingasetshenziswa njengabaphakathi ekuhlanganisweni kwezidakamizwa noma ama-peptide asebenzayo.

 

Indlela Yokulungiselela:

Ukulungiswa kwe-Fmoc-Gln-OH kungafezwa ngalezi zinyathelo ezilandelayo:

1. Okokuqala, i-glutamine isabela nge-fluoric anhydride (Fmoc-OSu) ukuze ithole i-Fmoc-Gln-OH acid fluoride (Fmoc-Gln-OF).

2. Bese, i-Fmoc-Gln-OF iphendulwa nge-pyridine (Py) noma i-N,N-dimethylpyrrolidone (DMAP) ngaphansi kwezimo eziyisisekelo ukukhiqiza i-Fmoc-Gln-OH.

 

Ulwazi Lokuphepha:

-I-Fmoc-Gln-OH ngokuvamile iphephile ngaphansi kwezimo zokusebenza ezivamile, kodwa kusadingeka ukuthobela izinqubo zokuphepha zaselabhorethri.

-Qaphela ukuthi ungathintani nesikhumba, amehlo noma ulwelwesi lwamafinyila, futhi ugweme ukuhogela umoya noma ukukungenisa.

-Ngesikhathi sokusebenzisa, ungagqoka izinto zokuzivikela ezifanele, njengamagilavu ​​aselabhorethri, izibuko zokuphepha nezingubo zaselabhorethri.

-Uma kwenzeka ingozi noma ukungakhululeki, funa usizo lwezokwelapha kusenesikhathi futhi ulethe ulwazi oluningiliziwe ngamakhemikhali ukuze uthole ireferensi.

  • Okwedlule:
  • Olandelayo:
    • Bhala umyalezo wakho lapha futhi usithumelele wona
