Kugwiritsa Ntchito Malic Acid Ndi Kaphatikizidwe

Kufotokozera	L-Malic acid imakhala yopanda fungo (nthawi zina kukomoka, fungo la akridi) yokhala ndi kukoma kwa tart, acidic.Ndi zosapungent.Akhoza kukonzekera ndi hydration wa asidi maleic;mwa kupesa kuchokera ku shuga.
Chemical Properties	L-Malic acid imakhala yopanda fungo (nthawi zina kukomoka, fungo lokoma).Pagululi lili ndi tart, acidic, kukoma kosasangalatsa.
Chemical Properties	njira yabwino yopanda mtundu
Zochitika	Amapezeka mu mapulo sap, apulo, vwende, papaya, mowa, vinyo wamphesa, koko, chifukwa, kiwifruit ndi mizu ya chicory.
Ntchito	L-Malic acid imagwiritsidwa ntchito ngati chowonjezera cha chakudya, Chosankha α-amino kuteteza reagent kwa zotumphukira za amino acid.Synthon yosinthasintha pokonzekera mankhwala a chiral kuphatikizapo κ-opioid receptor agonists, 1α,25-dihydroxyvitamin D3 analogue, ndi phoslactomycin B.
Ntchito	Chomwe chimachitika mwachilengedwe ndi mawonekedwe a L omwe amapezeka mu maapulo ndi zipatso ndi zomera zina zambiri.Kusankha α-amino kuteteza reagent kwa zotumphukira amino acid.Synthon yosinthika pokonzekera mankhwala a chiral kuphatikizapo κ-opioid rece
Ntchito	Wapakatikati mu kaphatikizidwe ka mankhwala.Chelating ndi buffering wothandizira.Zonunkhira, zowonjezera kukoma komanso acidulant muzakudya.
Tanthauzo	ChEBI: Mtundu wowoneka bwino wa malic acid wokhala ndi (S) -kusintha.
Kukonzekera	L-Malic acid akhoza kukonzedwa ndi hydration wa asidi maleic;mwa kupesa kuchokera ku shuga.
Kufotokozera Kwambiri	L-Malic acid ndi organic acid yomwe imapezeka mu vinyo.Zimagwira ntchito yofunika kwambiri pakukhazikika kwa vinyo wa microbiological.
Zochita za Biochem/physiol	L-Malic acid ndi gawo la metabolism yama cell.Kugwiritsa ntchito kwake kumazindikiridwa muzamankhwala.Ndiwothandiza pochiza matenda a chiwindi, ogwira ntchito motsutsana ndi hyper-ammonemia.Amagwiritsidwa ntchito ngati gawo la kulowetsedwa kwa amino acid.L-Malic acid imagwiranso ntchito ngati nanomedicine pochiza matenda a ubongo.TCA (Krebs cycle) wapakatikati ndi mnzake mu malic acid aspartate shuttle.
Njira Zoyeretsera	Crystallize S-malic acid (malala) kuchokera ku ethyl acetate/pet ether (b 55-56o), kusunga kutentha kosachepera 65o.Kapena sungunulani ndi refluxing mu magawo khumi ndi asanu a anhydrous diethyl ether, decant, concentrate to the third volume and crystallize it pa 0o, mobwerezabwereza mpaka kusungunuka kosalekeza.[Beilstein 3 IV 1123]
