N-Carbobenzyloxy-DL-alanine ke motsoako oa tlhaho, o atisang ho khutsufatsoa e le Cbz-DL-Ala. E latelang ke tlhaloso ea sebopeho sa eona, tšebeliso, tlhahiso le tlhaiso-leseling ea polokeho:
Tlhaho:
N-Carbobenzyloxy-DL-alanine ke kristale e tšoeu e tiileng e nang le foromo ea molek'hule ea C12H13NO4 le boima bo amanang le molek'hule ea 235.24. E na le litsi tse peli tsa chiral mme ka hona e bonts'a li-isomers tsa optical. E ka qhibiliha ka har'a metsoako e mengata ea tlhaho, joalo ka joala le dimethylformamide. Ke motsoako o tsitsitseng mme o batla o le thata ho bola.
Sebelisa:
N-Carbobenzyloxy-DL-alanine ke ntho e sebelisoang hangata ho sireletsa amino acid. E ka sebelisoa ho kopantseng li-peptide le liprotheine moo lihlopha tsa eona tsa carboxyl le amine li ka hokahanngoang ke karabelo ea condensation lipakeng tsa amino acid ho theha liketane tsa peptide. Sehlopha se sireletsang N-benzyloxycarbonyl se ka tlosoa ka maemo a loketseng ka mor'a ho phethoa ha karabelo ho tsosolosa sebopeho sa pele sa amino acid.
Mokhoa oa ho itokisa:
Ho lokisoa ha N-Carbobenzyloxy-DL-alanine hangata ho etsoa ho sebelisoa N-benzyloxycarbonyl-alanine le tekanyo e loketseng ea DCC (diisopropylcarbamate) ka sehlapolli se loketseng. Karabelo e senya metsi ho theha sebopeho sa amide, se hloekisoang ka kristale ho fana ka sehlahisoa se lakatsehang.
Lintlha tsa Tšireletseho:
N-Carbobenzyloxy-DL-alanine hangata e bolokehile ha e sebelisoa tlas'a maemo a loketseng a ts'ebetso. Leha ho le joalo, kaha ke lik'hemik'hale, litataiso tsa mekhoa e sireletsehileng ea laboratori li ntse li hloka ho lateloa. E ka khopisa mahlo le letlalo, kahoo roala lisebelisoa tse loketseng tsa ho itšireletsa tse kang liatlana le likhalase nakong ea ts'ebetso. Ho phaella moo, e lokela ho bolokoa sebakeng se omileng, se nang le moea o motle, hole le mollo le lisebelisoa tse tukang. Bakeng sa tlhaiso-leseling e batsi mabapi le ho ts'oaroa le ho ts'oaroa ha bona ka mokhoa o bolokehileng, sheba leqephe le amehang la lintlha tsa polokeho (SDS) la k'hemik'hale kapa buisana le setsebi.
