D-Tyrosine (HD-Tyr-OH) (CAS: 556-02-5), waikawa amino me nga pärönaki, whakamahia i roto i te whakahiato peptide, whakamahia hei takawaenga whakahiato waro, takawaenga rongoa, kai / kai taapiri, taapiri kai, reagent biochemical. reagent matū ranei.
Ko D-Tyrosine te D-form amino acid o Tyrosine.He waikawa amino-kore.I roto i nga kararehe, ka taea te whakahiato mai i te phenylalanine.Koia hoki te tohu o te epinephrine, thyroid, hormones me te melanin.Otirā, kua whakaatuhia e te rangahau ka taea te tango i te tohu o te chiral ki nga aukati kaha o te tangata Nonpancreatic secretory phospholipase A 2(IIa) me te kaha o te mahi anti-inflammatory.Ka taea hoki te whakamahi hei rauemi timatanga mo te whakarite anisomycin.
Ko te D-Tyrosine he puna pūmua-kore o nga waikawa amino chiral, e whakamahia nuitia ana i roto i te whakahiato o nga raau taero chiral.Hei tauira, ko te peptide tarukino atosiban synthesized ki D-Tyrosine hei takawaenga chiral ko te tarukino tocolytic, me te deacetylated anisomycin synthesized he antigenic, anti-Amoeba, anti-fungal, anti-pupuhi, ki te ārai i te mahi o te mate fungal tipu, Ko nga raau taero peptide waihanga mo te maimoatanga o nga pukupuku kino me te whaihua motuhake, ka taea hoki te whakamahi mo nga ngongo, te punaha nerve pokapū, nga hononga, te endocardium, nga kanohi, nga taringa, te kiri, te gastrointestinal, te mumura o te punaha urinary me te tino pai o nga raau taero anti-inflammatory.
Ko te tikanga whakaputa me te DL-Tyrosine hei rauemi mata, ko te tauhohenga acylation me te Chloroacetyl Chloride i mahia, ka tātarihia me te kukū, ka tangohia te hua ki te acetone kohua, ka whakamarokehia mai i te hinu ether, ka rerystallized ano i muri i te waikawa ki te waikawa puota.
