Malic acid

acid Malic oksiyantarnaya (NOOSSN2SN Formula (OH) COOH), hydroxycarboxylic dibasic (midho acid). Waxaa la matalo walax crystalline Biyuhu. Malic acid waa si fiican u milma in ethanol iyo biyo, si liidata - in ether.

walax waxa uu leeyahay a daahirintiisa aawadeed, anti-oxidant, anti-bararka, fuuq iyo guryaha tannic fudud.

Under xaaladaha dabiiciga ah, caadi acid L-malic. barta barafku - boqol darajo. Aadka L. biyo. milmi The of ethanol 68,3 g ether preservative - 1.9 grams halkii boqol garaam oo dareeraha.

D-malic acid uu leeyahay heerkul barafku ka mid ah 130,8 digrii ah. Milmi in ethanol - 35,9 g, preservative ether - 0.6 grams halkii boqol garaam oo dareeraha.

Labada walxaha waa beelaya in benzene.

Malic acid ka fadilnaa kiimikada guryaha oxyacids. Its cusbada iyo esters gudbiyo Malatya. Marka kululeeyo si boqol darajo dhacdaa beddelidda ee anhydride acid malic, lactide ah isku. In ka badan kululaynta dheer (ilaa 140-150 degrees) fududeeyaa reebay oo biyo ah. Sidaas darteed, beddelidda ee malic acid in fumaric acid, iyadoo kor u kululaynta deg deg ah in mid ka mid boqol iyo siddeetan degrees weli la sameeyey, iyo anhydride maleic.

NOOSSN2SN (OH) COOH waxaa loo arkaa mid ka mid ah qaybaha ugu muhiimsan dhexe ee geeddi socodka dheefshiidka ee noolaha. Malic acid waxaa ku lug-shiid ee foomka of malate. Waxaa la aasaasay in wareegga acid tricarboxylic, gluconeogenesis at. Malate ka dib markii reactions enzymatic waxaa loo roggi karaa pyruvate, fumarate, oxaloacetate.

COOH Diyaar NOOSSN2SN (OH) by yareynta acid tartaric, hydrolysis of D, L- acid bromyantarnoy.

In warshadaha NOOSSN2SN (OH) COOH loo isticmaalo soo saaridda ee alaabta macmacaanka iyo biyaha midhaha. Oo malic acid waxaa loo isticmaalaa in winemaking. walax Khusayso sida burinna pH ah iyo wakiilka iidaan ah.

Diyaariyey malic acid (D, L) marka celinta oksaliluksusnoy acid ahaan nuguli uu NOOSSOSN2SOON Na ama ay hydrolysis (oksaliluksusnoy acid) ee Ester soo kabsaday.

walaxda si dabiici ah ka dhaca helay acid midhaha. Kuwaas oo si gaar ah waxaa ka mid ah tufaax aan weli qaan gaadhin, miraha ash buur, gooseberries, rhubarb. In tubaakada malic acid waxaa ku jira foomka of cusbo calcium. Inta ay yar waxaa ka mid ah waxaa laga heli karaa khamrigii. In dabiiciga ah NOOSSN2SN (OH) COOH waxaa la aasaasay sabab u ah geeddi-socodka lagu qayilo dhamaystirnayn oo sonkor. Gaar ahaan in a qadar weyn malic acid waxaa lagu ogaan karaa in canab qaan gaadhin (ka toban ilaa shan iyo toban grams halkii dm3). Inta lagu jiro fulan tirada midho NOOSSN2SN (OH) COOH hoos u dhigay laba ilaa shan garaam halkii dm3. hoos u dhac noocan oo kale ah ee fiirsashada ay sabab u tahay xaqiiqada ah in maalkiisu waa si firfircoon uga qayb qaataan geeddi socodka neefsashada. Waa in la ogaadaa in canab ka soo gobollada waqooyi helay weyn acid malic badan in miraha ka soo gobollada koonfurta. Tusmada NOOSSN2SN (OH) COOH, sidoo kale waxay ku xiran tahay xaaladaha cimilada inta lagu guda jiro sanadka oo kala duwan oo Cinab ah.

Marka halsano khamriga amarka ahaa shan iyo labaatan boqolkiiba malic acid nuugo khamiir. Inta lagu guda jiro formation of khamriga iyo soo celinta carbon dioxide. natiijada halsano jeermisyada in formation of khayroon daahirnimo sare succinic acid. Uumiga NOOSSN2SN (OH) COOH iyo HOL ereygu waa uracil salka (component RNA).

Under saameynta ay bakteeriyada melkesyrebakterier xaqiro laga yaabaa malic acid in jėrto. NOOSSN2SN (OH) COOH saamaysaa dhadhanka oo khamri ah. content sare ee malic acid waxay sababtaa "ashitada cagaaran" - dhadhan af badan. Xaaladahan, waxaa fuliyay noolaha "ashitada". Mabda 'habka ku salaysan yahay awoodda khamiirka iyo jėrto bakteeriyada nuugo NOOSSN2SN (OH) COOH.
