Isicelo:

I-D-Tyrosine (i-HD-Tyr-OH) (i-CAS: i-556-02-5), i-amino acids kunye ne-derivatives, isetyenziswe kwi-peptide synthesis, isetyenziswe njenge-organic synthesis intermediate, i-pharmaceutical intermediate, izongezo zokutya / zokutya, izongezo zesondlo, i-biochemical reagent. okanye reagent yeekhemikhali.
I-D-Tyrosine yi-D-form ye-amino acid yeTyrosine.Yi-amino acid engabalulekanga.Kwizilwanyana, inokuba yi-de novo eyenziwe kwi-phenylalanine.Ikwayi-precursor ye-epinephrine, i-thyroid, ihomoni kunye ne-melanin.Ngokukodwa, uphando lubonise ukuba lunokuthi luthathwe i-chiral precuor kwi-inhibitors ezinamandla zomntu we-Nonpancreatic secretory phospholipase A 2 (IIa) kunye nomsebenzi onamandla ochasayo.Inokusetyenziswa kwakhona njengento yokuqala yokulungiswa kwe-anisomycin.
I-D-Tyrosine ngumthombo ongeyiyo iprotheni ye-chiral amino acids, esetyenziswa ngokubanzi kwi-synthesis yeziyobisi ze-chiral.Ngokomzekelo, ichiza le-peptide i-atosiban eyenziwe kunye ne-D-Tyrosine njenge-chiral intermediate lichiza le-tocolytic, kwaye i-anisomycin eyenziwe yi-deacetylated ine-antigenic, i-anti-Amoeba, i-anti-fungal, i-anti-dumba, ukukhusela indima yesifo sokungunda kwezityalo, amachiza enziweyo epeptide kunyango lwamathumba anobungozi asebenza ngendlela ekhethekileyo, angasetyenziselwa imiphunga, inkqubo yemithambo-luvo ephakathi, amalungu, i-endocardium, amehlo, iindlebe, ulusu, isisu, ukudumba kwenkqubo yomchamo kunye nokusebenza kakuhle kakhulu kweziyobisi ezichasayo.
Indlela yokuvelisa kunye ne-DL-Tyrosine njengento eluhlaza, i-acylation reaction kunye ne-Chloroacetyl Chloride yenziwa, yahluzwa kwaye yagxininiswa, imveliso yakhutshwa nge-acetone ebilayo, iphinda iphinde ifakwe kwi-ether ye-petroleum, kwaye iphinde iphinde iphinde iphinde iphinde iphinde iphinde ifakwe kwi-acidification nge-hydrochloric acid.
