Selelekela

N-alpha-fluorene methoxycarbonyl-N-epsilon-tert-butoxycarbonyl-L-lysine ke motsoako oa maiketsetso hangata o hlalosoang ke khutsufatso ea Fmoc-Ls (Boc) -OH.

 

Boleng:

1. Ponahalo: hangata phofo e tšoeu kapa e tšoeu ea kristale.

2. Solubility: e qhibilihang ka har'a li-solvents, tse kang dimethyl sulfoxide (DMSO) le methanol mocheso oa kamore.

3. Botsitso: E ka tsitsa tlas'a maemo a tloaelehileng a liteko.

 

Sebelisa:

1. Tšebeliso e ka sehloohong ke sehlopha sa tšireletso ea amino acid le ion e ntle ea ho qala lintho tse entsoeng ka organic synthesis.

2. Hangata e sebelisoa ka peptide synthesis le protheine synthesis ho fetola liketane tsa amino acid le ho haha ​​liketane tsa peptide.

 

Mokhoa:

Mokhoa o tloaelehileng oa ho lokisa Fmoc-Ls(Boc) -OH ke ka tsela ea maiketsetso. Mehato e tobileng e ka kenyelletsa liketso tse ngata, tse kang esterification, aminolysis, deprotection, joalo-joalo Mokhoa oa ho itokisa o hloka hore ho sebelisoe li-reagents le maemo a itseng ho netefatsa bohloeki bo phahameng le chai.

 

Lintlha tsa Tšireletseho:

1. Mekhoa ea ts'ebetso ea ts'ireletso ea mantlha e tlameha ho lateloa ha e sebelisoa, ho kenyelletsa ho roala lisebelisoa tse loketseng tsa ho itšireletsa (joalo ka liatlana, likhalase) le ho sebetsa tlas'a maemo a laboratori a kenang hantle.

2. Motsoako o lokela ho bolokoa hantle le ho lahloa, ho qoba ho kopana le lintho tse sa lumellaneng, le ho o lahla ho latela melao le melaoana e amehang.

3. Haeba u na le mathata a itseng a tšireletso kapa litlhoko, ka kopo sheba litsebi tse amehang tsa lik'hemik'hale kapa u buisane le litsebi tse amehang.
