Classification NOOSSN2SN acid (OH) COOH

Tlas'a maemo a tlhaho, ho tloaelehile hore batho L-malic acid e. Qhibiliha ntlha - likhato lekholo. Haholo qhibilihang ka har'a metsi. The solubility ea ethanol 68,3 g, diethyl phenylate - dikgerama 1,9 ka dikgerama lekholo la solvent.

D-malic acid e na le qhibiliha mocheso oa likhato tse 130,8. Solubility ka ethanol - 35,9 g,, diethyl phenylate - dikgerama tse 0.6 ka dikgerama lekholo la solvent.

Bobeli dintho di insoluble ka benzene.

Malic acid e filoe lik'hemik'hale thepa oxyacids. matsoai lona le esters hlalositsweng Malatya. Ha halefile ho likhato lekholo le hlaha ka tšokoloho ea acid e anhydride malic, e tsoanang lactide. Fetang futhumatsang ka nako e telele (ho fihlela ho 140-150 likhato) ntsetso-peleng felisoa ha metsi. Ka lebaka leo, tšokoloho ea acid e malic ho acid e fumaric, ka futhumatsang ka potlako ho fihlela ho likhato tse lekholo le mashome a robeli Ho thehoa leha ho le joalo, 'me maleic anhydride.

NOOSSN2SN (OH) COOH e nkoa e mong oa metsoako e bohlokoa ka ho fetisisa lipakeng tsa dithulaganyo tshilong ya dijo ka lintho tse phelang. asiti Malic ho akarelletsa le metabolism ka mokgwa wa malate. E thehoa ka acid e potoloho tricarboxylic, gluconeogenesis ka. Malate mor'a liphetoho enzymatic ka fetoloa pyruvate, fumarate, oxaloacetate.

The ntho ea tlhaho etsahalang fumanoa ka acid e ea litholoana. Tsena ka ho khetheha e akarelletsa ho liapole immature, litholoana lithaba molora, gooseberries, rhubarb. Ka koae acid e malic e leng ka mokgwa wa k'halsiamo letsoai. The e nyenyane ea eona e ka fumanoa veine. Ka tlhaho NOOSSN2SN (OH) COOH Ho thehoa ka lebaka la ho fella ho kena moea tshebetso ya tsoekere. Haholo-holo ka e kholo chelete malic acid e ka lemoha ka morara immature (ho tloha dikgerama lesometharo ho leshome le metso e mehlano ka dm3). Nakong ea ripening palo tholoana NOOSSN2SN (OH) COOH fokotswa ho dikgerama tse peli ho tse hlano ka dm3. Joalo ea fokotseha ka mahloriso le e loketseng e le hantle hore ntho e amehang ka mafolofolo dithulaganyo ho hema. Re lokela ho hlokomela hore ka morara ho tloha libakeng tse ka leboea fumanoa asiti e khōloanyane malic feta ka ditholwana libaka ka boroa. Tse ka Hare NOOSSN2SN (OH) COOH, hape e itšetlehile ka maemo a boemo ba leholimo nakong ea selemo le ka tse fapa-fapaneng tsa morara.

Ha joala belisoa ea ka taelo ea acid e etsang liphesente tse mashome a mabeli a metso e mehlano malic monya tomoso. Nakong ea sebopeho sa joala le hlaphoheloa carbon dioxide. diphetho baktheria belisoa ka sebopeho sa phahameng hloekileng acid e succinic. Condensation NOOSSN2SN (OH) COOH le urea tswakana ke botlaaseng uracil (RNA motsoako).

Tlas'a tšusumetso ea libaktheria lactic acid e ka 'na degrade acid e malic ho acid e lactic. NOOSSN2SN (OH) COOH ama tatso ea veine. The dikahare tse phahameng tsa acid e malic etsa hore "tala acidity" - tatso e bohale. Maemong ana, ho phethahatsoa tsa likokoana-hloko "acidity". thulaganyou e molao-motheo o thehiloe bokhoni ba tomoso le asiti lactic libaktheria monya NOOSSN2SN (OH) COOH.
