Malic asidhi

Malic asidhi (Formula NOOSSN2SN (OH) COOH) oksiyantarnaya, dibasic hydroxycarboxylic (muchero acid). It inomiririrwa Hauoneki crystalline fuma. Malic asidhi zvakanaka soluble mu panyaya iyi uye mvura, taita - mu Eteri.

The fuma ane kucheneswa, Anti oxidant, Anti-anogumbura, hydrating uye munyoro astringent zvivako.

Kupatsanura NOOSSN2SN acids (OH) COOH

Under dzinongoitika ezvinhu, zvakafanana L-malic acid. Utsotso pfungwa - madhigirii zana. Zvikuru soluble mumvura. The solubility panyaya iyi 68,3 d diethyl Eteri - 1.9 magiramu por zana magiramu ose solvent.

D-malic asidhi ane utsotso tembiricha kuti 130,8 inegumi. Solubility mu panyaya iyi - 35.9 g, diethyl Eteri - 0,6 magiramu por zana magiramu ose solvent.

Zvose zvinhu zviri insoluble mu benzene.

Malic asidhi akapa namakemikari ehupfumi oxyacids. munyu ayo uye esters raireva Malatya. Kana neshungu kune madhigirii zana kumbowanikwa kutendeuka malic iine acid anhydride, ane fingapirindi lactide. Over kwenguva refu kudziyisa (kusvika 140-150 madhigirii) hwezvekukurukurirana kubviswa mvura. Somugumisiro, kutendeuka malic asidhi kuti fumaric acid, pamwe nokukurumidza kudziyisa kusvika zana namakumi masere madhigirii aumbwa asi, uye maleic anhydride.

NOOSSN2SN (OH) COOH ichaongororwa chimwe chezvinhu zvinokosha zvenguva zvinoumba metabolic pezvakaitwa mu zvipenyu. Malic asidhi rinobatanidzwa muviri muchimiro malate. Zvinonzi akaumba mune tricarboxylic iine acid kutenderera, gluconeogenesis pa. Malate pashure enzymatic siyana zvinogona dzikwanise pyruvate, fumarate, oxaloacetate.

Wakagadzirira NOOSSN2SN (OH) COOH kubudikidza rutapudzo pamusoro tartaric acid, hydrolysis pamusoro D, L- bromyantarnoy acid.

In indasitiri NOOSSN2SN (OH) COOH rakashandiswa kugadzirwa kwezvinhu confectionery zvinhu uye muchero mvura. Uye malic asidhi inoshandiswa winemaking. Zvinoshanda fuma sechinhu ph adjuster uye uhwiro mumiririri.

Agadzirira malic asidhi (D, L) kana kudzorera oksaliluksusnoy asidhi NOOSSOSN2SOON Na amalgam kana ayo hydrolysis (oksaliluksusnoy acid) kuti akatorazve Esteri.

The sezvingatarisirwa kuitika fuma yakawanikwa muchero acid. Izvi zvikuru zvinosanganisira saibva maapuro, gomo dota zvibereko, gooseberries, rhubarb. In fodya malic asidhi zvirimowo muchimiro calcium munyu. The shoma rinogona kuwanikwa waini. Zvakasikwa NOOSSN2SN (OH) COOH achiumbwa nokuda kukwana oxidation chirongwa shuga. Kunyanya yakawanda malic asidhi dzinogona kuonekwa mune mazambiringa saibva (kubvira gumi kusvika gumi magiramu muzana dm3). Panguva ichiibvira nhamba muchero NOOSSN2SN (OH) COOH wakaderedzwa kusvika maviri nemashanu magiramu muzana dm3. vasanyanye chakadaro wevasungwa nokuda ndechokuti fuma iri kuitika mu kufema kwendangariro. Zvinofanira kucherechedzwa kuti mazambiringa kubva kuchamhembe kunzvimbo akawana mukuru malic asidhi pane michero kubva kumaodzanyemba kumatunhu. Mukati NOOSSN2SN (OH) COOH, inobvawo pane mamiriro okunze panguva gore uye dzakasiyana-siyana mazambiringa.

Kana doro chinovira pakati sezvakarayirwa maviri nezvishanu kubva muzana malic asidhi yekubata mbiriso. Munguva paumbwe doro nekuona carbon dioxide. Chirwere chinovira zvabuda pakugadzirwa yakakwirira kutsvinda succinic acid. Condensation NOOSSN2SN (OH) COOH uye urea usage ndiye nechepasi uracil (RNA chikamu).

Nokupesvedzera lactic asidhi mabhakitiriya anogona zvinoshatisa malic asidhi kune lactic acid. NOOSSN2SN (OH) COOH kunokanganisa manakiro waini. Mukuru zviri malic asidhi kunokonzera "munyoro acidity" - jeko kuravira. Muzviitiko izvi, yakatakura kunze zvoutachiona "acidity". muitiro musimboti inobva mano mbiriso uye lactic asidhi bacteria Sechipanji NOOSSN2SN (OH) COOH.
