Usetyenziso

I-Boc-L-Asn-OH, eyaziwa ngokuba yi-BOC-L-Asparagine, iyimfuneko ebalulekileyo ye-amino acid kunye nezicelo ezahlukeneyo.

Okokuqala, i-Boc-L-Asn-OH ifumana ukusetyenziswa ngokubanzi kwi-biochemistry kunye nokufunyanwa kweziyobisi.Isebenza njengenxalenye ephambili kwi-peptide synthesis, eyenza ukwakhiwa kwamatyathanga e-peptide kunye nemisebenzi ethile yebhayoloji.Ngenxa yeempawu zayo zeekhemikhali ezikhethekileyo, i-Boc-L-Asn-OH inokusabela kunye nezinye i-amino acids okanye i-compounds, ekhokelela ekuveliseni izidakamizwa ezinoveli okanye iamolekyu ze-bioactive ezinemisebenzi eyahlukileyo.

Okwesibini, i-Boc-L-Asn-OH nayo inezicelo kwi-biotechnology kunye nebhayoloji yemolekyuli.Inokuthi isebenze njenge-amino acid ekhusela i-monomer, ikhusela amaqela asebenzayo kwezinye i-amino acids okanye i-peptide chains kwii-chemical reactions ezingafunekiyo ngexesha lokudibanisa okanye ukuhlanjululwa.Ukongezelela, i-Boc-L-Asn-OH ingasetyenziselwa ukuguqulwa kwendawo ethile kubunjineli beprotheni, ukuguqula isakhiwo kunye nomsebenzi weeprotheni.

Ngapha koko, ngokweendlela zobuchule bokuvelisa, i-Boc-L-Asn-OH inokwenziwa ngokusabela kweekhemikhali ezithile.Ngokuqhelekileyo, ilungiswa ngokusebenzisa i-tert-butoxycarbonyl chloride (okanye i-azide) kunye ne-L-asparagine njengezinto zokuqala.Ukusabela kwe-acylation kulandelwa yi-acidification usebenzisa i-citric acid kwaye emva koko ukuhlanjululwa ngokuphindaphindiweyo.Le nkqubo yokuvelisa yenza ukuba ulungelelwaniso olukhulu lwe-Boc-L-Asn-OH, ukuhlangabezana neemfuno zezicelo zayo ezahlukeneyo.
