I-D-Tyrosine (i-HD-Tyr-OH) (i-CAS: 556-02-5), ama-amino acid kanye nokuphuma, esetshenziswa ekuhlanganiseni kwe-peptide, esetshenziswa njenge-organic synthesis intermediate, imithi ephakathi nendawo, izithasiselo zokudla / okuphakelayo, isengezo sokudla okunempilo, i-biochemical reagent. noma i-reagent yamakhemikhali.
I-D-Tyrosine yi-D-form amino acid ye-Tyrosine.Kuyi-amino acid engabalulekile.Ezilwaneni, ingaba yi-de novo eyenziwe nge-phenylalanine.Kubuye kube ngumanduleli we-epinephrine, i-thyroid, amahomoni kanye ne-melanin.Ngokukhethekile, ucwaningo luye lwabonisa ukuthi kungathathwa isandulela se-chiral kuma-inhibitor anamandla we-Nonpancreatic secretory phospholipase A 2(IIa) enomsebenzi oqinile wokulwa nokuvuvukala.Ingasetshenziswa futhi njengesiqalo sokulungiselela i-anisomycin.
I-D-Tyrosine ingumthombo ongewona wamaprotheni we-chiral amino acids, esetshenziswa kakhulu ekuhlanganiseni kwezidakamizwa ze-chiral.Isibonelo, isidakamizwa se-peptide i-atosiban ehlanganiswe ne-D-Tyrosine njenge-chiral intermediate iyisidakamizwa se-tocolytic, futhi i-anisomycin ehlanganisiwe ye-deacetylated ine-antigenic, i-anti-Amoeba, i-anti-fungal, i-anti-ukuvuvukala, ukuvimbela indima yesifo sesikhunta sezitshalo, Izidakamizwa ze-peptide zokwenziwa zokwelapha izimila eziyingozi ngokusebenza okukhethekile, zingasetshenziselwa amaphaphu, isimiso sezinzwa esiyinhloko, amalunga, i-endocardium, amehlo, izindlebe, isikhumba, i-gastrointestinal, ukuvuvukala kwesistimu yomchamo ngokusebenza kahle kakhulu kwezidakamizwa ezilwa nokuvuvukala.
Indlela yokukhiqiza ene-DL-Tyrosine njengempahla eluhlaza, ukusabela kwe-acylation nge-Chloroacetyl Chloride kwenziwa, kwahlungwa futhi kwagxilwa, umkhiqizo wakhishwa nge-acetone ebilayo, waphinda wahlungwa ku-petroleum ether, waphinde wahlungwa kabusha ngemva kokwenziwa kwe-acidification nge-hydrochloric acid.
