Malic acid

Malic acid (Formula NOOSSN2SN (OH) COOH) oksiyantarnaya, hydroxycarboxylic dibasic (iziqhamo acid). Oku imelwe into crystalline enemibala. Malic acid enyibilikayo kakuhle ethanol kunye namanzi, kakuhle - xa kaEtere.

Le nto iye ukucocwa, anti-oxidant, anti-ukudumba, hydrating kunye neempawu ezingephi astringent.

Classification NOOSSN2SN asidi (OH) COOH

Phantsi kweemeko zendalo, eqhelekileyo L-malic acid. Lokunyibilika - nekhulu degrees. Kakhulu enyibilikayo emanzini. Ukunyibilika ethanol 68.3 g diethyl kaEtere - 1.9 grams nganye ikhulu grams wesinyibilikisi.

D-malic acid na iqondo lobushushu yokunyibilika a degrees 130,8. Ukunyibilika in ethanol - 35,9 g, diethyl kaEtere - 0.6 grams nganye ikhulu grams wesinyibilikisi.

Zombini kuhlanganiswa izinto ezingenakunyibilika in benzene.

Malic acid inkululeko iipropati zeekhemikhali oxyacids. neetyuwa zaso, esters wabhekisela Malatya. Xa lashushu degrees nekhulu kwenzeka ukuguquka acetic malic acid, i lactide twatse. Phezu ukufudumeza elide (ukuya ku 140-150 degrees) lula ukuphelisa amanzi. Ngenxa yoko, uguqulo malic acid ukuya fumaric acid, kunye ezikhawulezayo kufudumeze ukuya ku ikhulu elinamanci asibhozo degrees ezikhandelwa okwangoku, kunye acetic maleic.

NOOSSN2SN (OH) COOH igqalwa enye yeendima ezibalulekileyo intermediate lweenkqubo pathways ngayo izinto eziphilayo. Malic acid libandakanyeka nethe ngokohlobo malate. It senziwa kumjikelo acid tricarboxylic, gluconeogenesis kwi. Malate emva reactions enzymatic inokujikwa ibe pyruvate, fumarate, oxaloacetate.

Okulungiselelweyo NOOSSN2SN (OH) COOH ngu ekunciphiseni tartaric acid, haydrolisis ka-D, L- bromyantarnoy acid.

Kushishino NOOSSN2SN (OH) COOH ezisetyenziswayo xa kwenziwa imveliso iimveliso confectionery kunye namanzi iziqhamo. Kwaye malic acid isetyenziswa iwayini. into esebenzayo njenge lwesikhonkwane pH kunye arhente flavoring.

Izimasekile malic acid (D, L) xa nokubuyisela oksaliluksusnoy asidi NOOSSOSN2SOON Na amalgam okanye haydrolisis yayo (oksaliluksusnoy acid) of Ester wachacha.

Le into yendalo efumaneka acid iziqhamo. Ezi ikakhulu ziquka ama-apile ubuntwana, ash intaba iziqhamo, gooseberries, rhubarb. Xa icuba malic acid iqulethwe ngokohlobo calcium yetyuwa. Imali esincinci ingafunyanwa kwi iwayini. Endalweni NOOSSN2SN (OH) COOH amiliswe ngenxa inkqubo engaphelelanga igcwala ngayo iswekile. Ingakumbi isixa esikhulu malic acid sivakala iidiliya ubuntwana (ukusuka grams ezilishumi elinesihlanu dm3 nganye). Ngexesha esivuthiweyo inombolo iziqhamo NOOSSN2SN (OH) COOH zancitshiswa grams ezimbini ukuya kwezintlanu dm3 nganye. Loo ukuhla xi ngenxa yokuba iziyobisi libandakanyeka kwiinkqubo zemiphunga. Kufuneka kuqatshelwe ukuba iidiliya evela kwimimandla esemantla wafumana malic acid ngaphezu ungeniselo evela kwimimandla esemazantsi. Iziqulatho NOOSSN2SN (OH) COOH, ikwaxhomekeke iimeko zemozulu kulo nyaka yaye ezahlukeneyo leediliya.

Xa ibile ezinxilisayo zomyalelo ezingamashumi amabini anesihlanu ekhulwini malic acid ukufunxa nagwele. Ngexesha lokusekwa utywala Nokubuyiselwa carbon dioxide. iziphumo ibile kwegciwane ekubunjweni ngobunyulu ophezulu succinic acid. Ulweliso NOOSSN2SN (OH) COOH kunye urea yokuqaphela ke uracil isiseko (component RNA).

Phantsi yempembelelo iintsholongwane acid lactic ukuze kwehlisa malic acid ukuya lactic acid. NOOSSN2SN (OH) COOH kuchaphazela ukungcamla iwayini. Umxholo aphezulu malic acid ebangela "iasidi green" - incasa elibukhali. Kule meko, wazithwala phandle "iasidi" begazi. Inkqubo siseko isekelwe phezu isakhono Igwele kunye lactic acid iintsholongwane ukufunxa NOOSSN2SN (OH) COOH.
