Lintho tsa 'mele le tsa lik'hemik'hale | 1. Ponahalo: kristale e tšoeu kapa phofo ea kristale. 2. Sollubility: e qhibiliha habonolo ka metsing, e qhibiliha hanyenyane ka har'a ethanol, e sa qhibilihe ka har'a ether, benzene, grease, joalo-joalo. 3. Ts'ebetso ea optical: Vithamine C e na le li-isomers tsa optical tse 4, 'me ho potoloha ho khethehileng ha tharollo ea metsi e nang le L-ascorbic acid ea 0.10 g / ml ke +20.5 ° -+21.5 °. 4. Acid: Vitamin C e na le enediol base, e nang le asiti, ka kakaretso e bonahatsoa e le asiti e bonolo e ka sebetsanang le sodium bicarbonate ho hlahisa letsoai la sodium. 5. Lintho tsa lik'habohaedreite: Sebopeho sa lik'hemik'hale tsa vithamine C se tšoana le sa tsoekere, se nang le thepa ea tsoekere, e ka sebelisoang ka hydrolyzed le decarboxylated ho hlahisa pentose e teng, 'me e tsoela pele ho lahleheloa ke metsi ho hlahisa, ho eketsa pyrrole le ho futhumatsa ho 50 ºC e tla hlahisa boputsoa. 6. Litšobotsi tsa ho monya ha ultraviolet: Ka lebaka la boteng ba li-conjugated bond tse peli ka limolek'hule tsa vithamine C, tharollo ea eona ea dilute e na le tekanyo e phahameng ea ho monya ho 243 nm wavelength, 'me boholo ba maqhubu a ho monya bo tla khutlisetsoa ho 265 nm tlas'a maemo a acidic kapa alkaline. 7.

Vithamine C e na le oxidized ho hlahisa sebopeho sa diketo-based dehydrovitamin C, dehydrovitamin C e ka fumanoa ka mor'a ho fokotseha ha hydrogenation ea vithamine C. Ho phaella moo, ka tharollo ea alkaline le tharollo e matla ea acid, dehydrovitamin C e ka tsoela pele ho hydrolyzed ho fumana diketogulonic acid. |
Mosebetsi wa fisioloji | 1. Hydroxylation Vithamine C e kenya letsoho karabelong ea hydroxylation 'meleng oa motho, e amanang le metabolism ea lintho tse ngata tsa bohlokoa' meleng oa motho. Ka mohlala, vithamine C e ka kenya letsoho le ho khothalletsa hydroxylation ea k'holeseterole ka bile acid; Ho ntlafatsa ts'ebetso ea oxidase ea ts'ebetso e kopaneng; E ameha ketsong ea hydroxylase 'me e khothalletsa motsoako oa li-neurotransmitters tsa amino acid 5-hydroxytryptamine le norepinephrine. 2. Antioxidant Vithamine C e na le reducibility e matla 'me ke antioxidant e ntle haholo e qhibilihang ka metsing, e ka fokotsang hydroxyl radicals, superoxides le li-oxide tse ling tse sebetsang' meleng oa motho, 'me e ka tlosa li-radicals tsa mahala le ho thibela lipid peroxidation. 3.
