D-Tyrosine (HD-Tyr-OH) (CAS: 556-02-5), amino acids thiab derivatives, siv nyob rau hauv peptide synthesis, siv los ua cov organic synthesis intermediate, tshuaj intermediate, khoom noj khoom haus / pub additives, khoom noj khoom haus ntxiv, biochemical reagent los yog tshuaj reagent.
D-Tyrosine yog D-form amino acid ntawm Tyrosine.Nws yog ib qho tsis tseem ceeb amino acid.Hauv cov tsiaj, nws tuaj yeem yog de novo synthesized los ntawm phenylalanine.Nws tseem yog tus thawj coj ntawm epinephrine, thyroid, hormones thiab melanin.Tshwj xeeb, txoj kev tshawb fawb tau pom tias nws tuaj yeem raug coj mus rau chiral precusor rau cov muaj zog inhibitors ntawm tib neeg Nonpancreatic secretory phospholipase A 2 (IIa) nrog rau kev ua kom muaj zog tiv thaiv.Nws kuj tseem siv tau los ua cov khoom pib rau kev npaj ntawm anisomycin.
D-Tyrosine yog ib qho uas tsis yog-protein qhov chaw ntawm chiral amino acids, uas yog dav siv nyob rau hauv lub synthesis ntawm chiral tshuaj.Piv txwv li, peptide tshuaj atosiban synthesized nrog D-Tyrosine raws li ib tug chiral intermediate yog ib tug tocolytic tshuaj, thiab cov synthesized deacetylated anisomycin muaj antigenic, anti-Amoeba, anti-fungal, anti-o, los tiv thaiv lub luag hauj lwm ntawm cov nroj tsuag fungal kab mob, Synthetic peptide tshuaj rau kev kho mob ntawm cov qog nqaij hlav nrog kev ua tau zoo tshwj xeeb, kuj tuaj yeem siv rau lub ntsws, hauv nruab nrab lub paj hlwb, pob qij txha, endocardium, qhov muag, pob ntseg, tawv nqaij, plab hnyuv, urinary system o nrog kev ua haujlwm zoo ntawm cov tshuaj tiv thaiv.
Cov txheej txheem ntau lawm nrog DL-Tyrosine raws li raw khoom, acylation cov tshuaj tiv thaiv nrog Chloroacetyl Chloride yog nqa tawm, lim thiab concentrated, cov khoom tau muab rho tawm nrog boiling acetone, recrystallized los ntawm roj av ether, thiab recrystallized dua tom qab acidification nrog hydrochloric acid.
