I-L-Tyrosine Ethyl Ester Hydrochloride (H-Tyr-OEt · HCl) (CAS: 4089-07-0) isetshenziswa njengezokwelapha kanye ne-organic intermediate futhi njenge-amino evikelayo ebalulekile.Iphinde isetshenziselwe ukwethula i-t-Boc protect gene.Okuphuma ku-amino acid, okusetshenziselwa ukuhlanganiswa kwe-peptide, i-organic synthesis intermediates, i-intermediate yemithi, ama-reagents we-biochemical, ama-chemical reagents.
Isingeniso: I-L-Tyrosine ingenye yama-amino acid angama-20 akha amaprotheni futhi iyi-amino acid ebalulekile ezilwaneni ezincelisayo.I-L-Tyrosine Ethyl Ester Hydrochloride yiyona nto eyinhloko yokusetshenziswa kwezinhlobonhlobo zamahomoni e-peptide, ama-antibiotics nezinye izidakamizwa.
Sebenzisa: I-L-Tyrosine Ethyl Ester Hydrochloride yiyona nto eyinhloko yokwakhiwa kwamahomoni e-peptide, ama-antibiotics nezinye izidakamizwa.Embonini yokudla, i-L-Tyrosine Ethyl Ester Hydrochloride isetshenziswa esikhundleni sama-amino acid njengezithasiselo zokudla, ezingashintsha ukunambitheka nokunambitheka kokudla futhi kwandise impilo yeshalofu yokudla.Ama-amino acid ester asetshenziswa ekudleni aphinde akhulise ukunyibilika kwama-amino acid kanye nokucaciswa kwe-enzyme catalysis, enenzuzo ekugayeni nasekumunceni umzimba futhi idlala indima embaxambili ekudleni nasekunakekelweni kwezempilo.
Indlela yokulungiselela: Faka u-19 mL we-anhydrous ethanol eflaskini enemilomo emithathu engu-250 mL efakwe i-stirrer, ifaneli yokuwisa kanye ne-thermometer, uyipholise ifike cishe ku -8℃ kubhavu kasawoti weqhwa ukuze isetshenziswe ngaphandle, kancane kancane wengeze u-2.4 mL i-sulfoxide chloride ngaphansi kokunyakaziswa (ukusheshisa okwehlayo kukhawulelwe ekushiseni okungadluli ku-0 ℃), ngemuva kokwehla, gxuma kulokhu kushisa ihora elingu-1, engeza u-4.5g L-Tyrosine ngaphansi kwezimo zokupholisa, ukhuphule izinga lokushisa ekamelweni bese ugoqa ukuze Amahora angu-2, bese kushisa futhi kuphinde kube ne-reflux ku-65 ℃ amahora angu-2, distill ngemva kokusabela ukuze kuhwamuke i-methanol eningi kanye ne-thionyl chloride eyeqile, dlulisela insalela kubhikha ukuze lipholiswe, engeza u-125 mL ethyl acetate ukuze kuqhume inani elikhulu lamakristalu, vacuum. ukuhlunga, nokuqoqa amakristalu, kwatholakala i-L-Tyrosine Ethyl Ester Hydrochloride.
