Imininingwane Yomkhiqizo

Omaka bomkhiqizo

I-N(ε)-benzyloxycarbonyl-L-lysine ingxube yemvelo enezici ezilandelayo:

Ukubukeka: I-crystalline powder emhlophe noma i-crystalline.
Ukunyibilika: Kunzima ukuncibilika emanzini, kuncibilika kuzixazululo ezine-asidi ne-alkaline nezincibilikisi eziphilayo njenge-ethanol nama-ether.
Izici zamakhemikhali: Iqembu layo le-carboxylic acid lingafinyezwa ngamaqembu e-amine ukuze kwakheke izibopho ze-peptide.

Ukusetshenziswa okuyinhloko kwe-N(ε)-benzyloxycarbonyl-L-lysine kuyiqembu elivikelayo lesikhashana ocwaningweni lwamakhemikhali ezinto eziphilayo. Ivikela iqembu lama-amino ku-lysine ukuze ilivimbele ekubambeni iqhaza ekuphenduleni okungaqondile. Lapho kuhlanganiswa ama-peptides noma amaprotheni, i-N(ε)-benzyloxycarbonyl-L-lysine ingasetshenziselwa ukuvikela bese ikhishwa uma kudingeka.

Ukulungiswa kwe-N(ε)-benzyloxycarbonyl-L-lysine kuvame ukutholakala ngokusabela i-L-lysine nge-ethyl N-benzyl-2-chloroacetate.
Kungase kucasule amehlo, isikhumba, kanye nendlela yokuphefumula futhi kufanele yelashwe ngokuthintana ngqo. Gqoka izibuko zokuzivikela, amagilavu ​​namamaski lapho usebenza. Kufanele igcinwe endaweni eyomile, epholile, kude nomlilo nama-oxidants.

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