I-Fmoc-DL-2-Aminobutyric acid (CAS# 174879-28-8) isingeniso

I-N-Fmoc-2-aminobutyric acid, eyaziwa nangokuthi i-N-(9-hemandryl)aminobutyric acid, iyinhlanganisela yezinto eziphilayo. Okulandelayo kuzochaza izakhiwo zayo, ukusetshenziswa, izindlela zokukhiqiza kanye nolwazi lokuphepha:

Ikhwalithi:
I-N-Fmoc-2-aminobutyric acid iqinile okumhlophe kuya kokuphuzi okukhanyayo okunezakhiwo ezincibilika kalula kuzincibilikisi zemvelo. Kuyinhlanganisela ene-asidi engakha usawoti futhi ineqembu elivikela i-phenyl (Fmoc) elingasuswa ngaphansi kwezimo ezine-asidi.

Sebenzisa:
I-N-Fmoc-2-aminobutyric acid isetshenziswa kabanzi ekuhlanganiseni kwe-peptide ku-organic synthesis. Iqembu layo lokuvikela i-phenyl lingavikela iqembu lama-amino ngesikhathi sokuhlanganiswa ukugwema ukusabela okungaqondile. Enqubweni ye-peptide synthesis, i-N-Fmoc-2-aminobutyric acid ivame ukusetshenziswa njenge-synthesis intermediate yokwakha amaketanga e-peptide, futhi ngemva kokuhlanganiswa, i-aminobutyric acid efiselekayo ingatholakala ngokususa iqembu lokuvikela i-phenyl.

Indlela:
Ukulungiswa kwe-N-Fmoc-2-aminobutyric acid ngokuvamile kufinyelelwa ngokwethula iqembu le-phenyl-protecting (Fmoc) ku-2-aminobutyric acid. Izinyathelo ezithile zibandakanya ukusabela ku-2-aminobutyric acid nge-Fmoc-Cl (i-chloride yeqembu le-Fmoc) kusinyibilikisi esifanelekile ukuze kukhiqizwe i-N-Fmoc-2-aminobutyric acid, bese kungena isinyathelo sokuhlanza esifanele ukuze kutholwe umkhiqizo oqondiwe.

Ulwazi Lokuphepha:
I-N-Fmoc-2-aminobutyric acid iyikhemikhali edinga izinyathelo zokuphepha ngesikhathi sokusetshenziswa. Kungase kucasule isikhumba, amehlo, nendlela yokuphefumula futhi kudinga ukugqokwa kwezinto ezifanele zokuzivikela ezifana namagilavu, izingubo zamehlo ezivikelayo, namamaski lapho usebenza. Inhlanganisela kufanele igcinwe futhi isingathwe kude nokuvutha kanye namazinga okushisa aphezulu ukugwema ukuthintana nezinto ezivuthayo. Uma uthinta isikhumba noma amehlo, hlambulula ngokushesha ngamanzi amaningi futhi uthintane nodokotela.
