Vitamin C(Vitamin C), alias Ascorbic acid (Ascorbic acid), cov mis mos molecular yog C6H8O6, yog polyhydroxyl compound uas muaj 6 carbon atoms, yog ib tug dej-soluble vitamin tsim nyog los tswj lub cev physiological ua hauj lwm ntawm lub cev thiab cov metabolic tsis xws luag. hlwb. Cov tsos ntawm cov ntshiab vitamin C yog dawb crystalline hmoov los yog crystalline hmoov, uas yog yooj yim soluble nyob rau hauv dej, me ntsis soluble nyob rau hauv ethanol, insoluble nyob rau hauv ether, benzene, roj, thiab lwm yam. Vitamin C muaj acidic, txo, optical kev ua si thiab carbohydrate zog, thiab muaj hydroxylation, antioxidant, tiv thaiv kab mob thiab detoxification cuam tshuam rau tib neeg lub cev. Kev lag luam yog tsuas yog los ntawm biosynthesis (fermentation) txoj kev los npaj cov vitamin C, vitamin C yog tsuas yog siv nyob rau hauv kev kho mob teb thiab zaub mov teb.
| Lub cev thiab tshuaj muaj zog | 1. Cov tsos: dawb crystalline hmoov los yog crystalline hmoov. 2. Solubility: yooj yim soluble hauv dej, me ntsis soluble hauv ethanol, insoluble hauv ether, benzene, roj, thiab lwm yam. 3. Kev ua haujlwm kho qhov muag: Vitamin C muaj 4 optical isomers, thiab cov kev sib hloov ntawm cov tshuaj aqueous uas muaj L-ascorbic acid ntawm 0.10 g / ml yog +20.5 ° - + 21.5 °. 4. Acid: Vitamin C muaj enediol puag, uas yog acidic, feem ntau manifested raws li ib tug yooj yim acid uas yuav hnov mob nrog sodium bicarbonate los tsim sodium ntsev. 5. Cov khoom carbohydrate: Cov qauv tshuaj ntawm cov vitamin C zoo ib yam li cov suab thaj, nrog cov khoom ntawm cov suab thaj, uas tuaj yeem hydrolyzed thiab decarboxylated los tsim pentose nyob rau hauv lub xub ntiag, thiab txuas ntxiv poob dej los tsim, ntxiv pyrrole thiab cua sov rau. 50 ºC yuav ua rau xiav. 6. Ultraviolet absorption yam ntxwv: Vim lub xub ntiag ntawm conjugated ob daim ntawv cog lus nyob rau hauv vitamin C molecules, nws dilute tov muaj ib tug siab tshaj plaws haum ntawm 243 nm wavelength, thiab lub siab tshaj plaws nqus wavelength yuav redshifted rau 265 nm nyob rau hauv acidic los yog alkaline tej yam kev mob. 7. Kev txo qis: pawg enediol nyob rau hauv cov vitamin yog reducible heev, ruaj khov nyob rau hauv ib puag ncig acidic, thiab yooj yim puas nyob rau hauv tshav kub, lub teeb, aerobic thiab alkaline ib puag ncig. Vitamin C yog oxidized los tsim ib tug diketo-raws li qauv ntawm dehydrovitamin C, dehydrovitamin C yuav tau tom qab hydrogenation txo ntawm vitamin C. Tsis tas li ntawd, nyob rau hauv alkaline kua thiab muaj zog acid tov, dehydrovitamin C tuaj yeem ntxiv hydrolyzed kom tau diketogulonic acid. |
| Physiological muaj nuj nqi | 1. Hydroxylation Vitamin C koom nrog cov tshuaj tiv thaiv hydroxylation hauv tib neeg lub cev, uas cuam tshuam rau cov metabolism hauv ntau yam tseem ceeb hauv tib neeg lub cev. Piv txwv li, vitamin C tuaj yeem koom nrog thiab txhawb cov hydroxylation ntawm cov cholesterol mus rau hauv cov kua tsib acids; Txhim khu kev sib xyaw ua haujlwm oxidase kev ua haujlwm; Nws koom nrog hauv kev ua hydroxylase thiab txhawb kev sib txuas ntawm amino acid neurotransmitters 5-hydroxytryptamine thiab norepinephrine. 2. Antioxidant Vitamin C muaj zog txo qis thiab yog cov dej-soluble antioxidant zoo heev, uas tuaj yeem txo cov hydroxyl radicals, superoxides thiab lwm yam oxides hauv tib neeg lub cev, thiab tuaj yeem tshem tawm cov dawb radicals thiab tiv thaiv lipid peroxidation. 3. Txhawb kev tiv thaiv Lub phagocytic kev ua haujlwm ntawm leukocyte muaj feem xyuam rau qib vitamin hauv plasma. Cov nyhuv antioxidant ntawm vitamin C tuaj yeem txo cov disulfide daim ntawv cog lus (-S - S -) hauv cov tshuaj tiv thaiv rau sulfhydryl (-SH), thiab tom qab ntawd txhawb kev txo qis ntawm cystine rau cysteine, thiab thaum kawg txhawb kev tsim cov tshuaj tiv thaiv. 4. Detoxify Cov koob tshuaj loj ntawm cov vitamin C tuaj yeem ua rau cov hlau hnyav xws li Pb2+, Hg2+, Cd2+, cov kab mob co toxins, benzene thiab qee cov tshuaj lysins. Lub ntsiab mechanism yog raws li nram no: lub zog reducibility ntawm vitamin C yuav tshem tawm oxidized glutathione los ntawm tib neeg lub cev, thiab ces tsim ib tug complex nrog hnyav hlau ions yuav tsum tau tawm ntawm lub cev; Vim tias cov pa oxygen hauv C2 txoj haujlwm ntawm vitamin C tsis zoo, vitamin C nws tus kheej kuj tuaj yeem ua ke nrog cov hlau ions thiab tawm hauv lub cev los ntawm cov zis; Vitamin C txhim khu kev ua haujlwm enzyme (hydroxylation) los pab txhawb kev tshem tawm cov tshuaj lom thiab tshuaj. 5. Absorption thiab metabolism Kev nqus ntawm vitamin C los ntawm kev noj zaub mov hauv tib neeg lub cev yog kev thauj mus los hauv cov hnyuv loj los ntawm tus neeg nqa khoom, thiab ib qho me me yog absorbed los ntawm passive diffusion. Thaum noj cov vitamin C tsawg, yuav luag txhua tus tuaj yeem nqus tau, thiab thaum noj txog 500 mg / d, tus nqi nqus yuav poob mus txog 75%. Cov vitamin C absorbed yuav sai sai nkag mus rau hauv cov ntshav ncig thiab nkag mus rau ntau yam ntaub so ntswg thiab lub cev ntawm lub cev. Feem ntau cov vitamin C yog metabolized hauv tib neeg lub cev rau hauv oxalic acid, 2, 3-diketogulonic acid, los yog ua ke nrog sulfuric acid los tsim ascorbate-2-sulfuric acid thiab tawm hauv cov zis; Ib txhia ntawm nws yog excreted nyob rau hauv cov zis. Tus nqi ntawm cov vitamin C tawm hauv cov zis yog cuam tshuam los ntawm kev noj cov vitamin C, lub raum ua haujlwm, thiab lub cim xeeb khaws cia hauv lub cev. |
| Txoj kev khaws cia | Tsis txhob khaws cia nrog cov oxidants muaj zog thiab alkalis, thiab khaws cia rau hauv lub thawv kaw uas muaj cov pa roj tsis zoo ntawm qhov kub thiab txias. |
