    Gukoresha aside Malike Gukoresha na Synthesis

    Ibisobanuro Acide L-Malic isa nkimpumuro nziza (rimwe na rimwe impumuro mbi, acrid) ifite tart, uburyohe bwa aside.Ntibisanzwe.Birashobora gutegurwa na hydration ya acide ya manic;na fermentation iva mubisukari.
    Ibikoresho bya Shimi Acide L-Malic isa nkimpumuro nziza (rimwe na rimwe impumuro mbi, acrid).Uru ruganda rufite tart, acide, uburyohe budasanzwe.
    Ibikoresho bya Shimi igisubizo kitagira ibara
    Ibibaho Bibaho muri saple sap, pome, melon, papaya, byeri, vino yinzabibu, cakao, kubera, kiwifruit n'umuzi wa chicory.
    Gukoresha Acide L-Malic ikoreshwa nk'inyongeramusaruro, Guhitamo α-amino ikingira reagent ikomoka kuri aside amine.Synthon itandukanye kugirango itegure ibice bya chiral harimo κ-opioid reseptor agonist, 1α, 25-dihydroxyvitamin D3 analogue, na foslactomycine B.
    Gukoresha Isomer isanzwe igaragara ni L-form yabonetse muri pome nizindi mbuto nyinshi nibimera.Guhitamo α-amino kurinda reagent kubikomoka kuri aside amine.Synthon itandukanye kugirango itegure ibice bya chiral harimo κ-opioid rece
    Gukoresha Hagati muri synthesis ya chimique.Umukozi wa chelating na buffering.Ibiryo biryoha, byongera uburyohe hamwe na acide mu biryo.
    Ibisobanuro ChEBI: Uburyo bukora neza bwa acide malic ifite (S) -iboneza.
    Kwitegura Acide L-Malic irashobora gutegurwa na hydrata ya acide ya manic;na fermentation iva mubisukari.
    Ibisobanuro rusange Acide L-Malic ni aside kama ikunze kuboneka muri vino.Ifite uruhare runini muri divayi mikorobe itajegajega.
    Ibikorwa bya Biochem / physiol L-Malike aside ni igice cya metabolism selile.Gushyira mu bikorwa byemewe muri farumasi.Ni ingirakamaro mu kuvura imikorere mibi ya hepatike, ikora neza kurwanya hyper-ammonemia.Ikoreshwa nkigice cyo kwinjiza aside amine.Acide L-Malic nayo ikora nka nanomedicine mu kuvura indwara zifata ubwonko.TCA (Krebs cycle) hagati kandi igafatanya muri shitingi ya malic acide.
    Uburyo bwo kweza Crystallize S-malic aside (amakara) uhereye kuri Ethyl acetate / pet ether (b 55-56o), bigatuma ubushyuhe buri munsi ya 65o.Cyangwa kuyishonga mugusubiramo ibice cumi na bitanu bya anhydrous diethyl ether, decant, kwibanda kuri kimwe cya gatatu hanyuma ukayitondekanya kuri 0o, inshuro nyinshi kugeza aho ihora ishonga.[Beilstein 3 IV 1123.]
