Isingeniso

I-FMOC-O-tert-butyl-L-threonine iyinhlanganisela enezici ezilandelayo:

 

Ukubukeka: I-crystalline emhlophe noma emhlophe eqinile.

Ukunyibilika: kuncibilika kuzincibilikisi zemvelo, njenge-dimethyl sulfoxide, N, N-dimethylformamide, njll., engancibiliki emanzini.

 

Ukusetshenziswa kwe-FMOC-O-tert-butyl-L-threonine:

I-Peptide synthesis: njengeqembu elivikelayo, isetshenziselwa ukuhlanganiswa kokulandelana kwe-peptide kanye nokusabela kokushintshaniswa kwe-ion ngaphakathi kwabo.

Ucwaningo lwe-biochemical: lokuhlanganiswa nokutadisha kwama-peptide emvelo namaprotheni.

 

Indlela yokulungiselela ye-FMOC-O-tert-butyl-L-threonine:

I-FMOC-O-tert-butyl-L-threonine ingahlanganiswa ngezinyathelo ezilandelayo:

I-L-threonine isabela nge-FMOC-O-tert-butyl-N-hydroimide ukuze kukhiqizwe i-FMOC-O-tert-butyl-L-threonine-N-agar powder ester.

I-FMOC-O-tert-butyl-L-threonine-N-agar powder ester yenziwe nge-hydrolyzed ukuze ithole i-FMOC-O-tert-butyl-L-threonine.

 

Ulwazi lokuphepha lwe-FMOC-O-tert-butyl-L-threonine:

Gwema ukuthintana ngqo nesikhumba namehlo, ukucasuka nokungezwani komzimba kungenzeka.

Sicela usebenze endaweni enomoya omuhle futhi ugweme ukuhogela umhwamuko noma uthuli.

Kufanele ivalwe ngokuqinile lapho igcinwa futhi igweme ukuthintana nama-oxidants.

Sebenzisa izindlela zokuzivikela ezifana namagilavu ​​okuzivikela, izibuko, namajazi elebhu ngesikhathi sokusetshenziswa.
