Vitamin C(Vitamin C), alias Ascorbic acid (Ascorbic acid), cov mis molecular yog C6H8O6, yog ib qho polyhydroxyl compound uas muaj 6 carbon atoms, yog ib qho vitamin-soluble hauv dej uas tsim nyog los tswj lub cev ua haujlwm ib txwm thiab cov tshuaj metabolic tsis zoo ntawm cov hlwb. Cov tsos ntawm cov vitamin C ntshiab yog dawb crystalline hmoov, uas yooj yim soluble hauv dej, me ntsis soluble hauv ethanol, insoluble hauv ether, benzene, roj, thiab lwm yam. Vitamin C muaj acidic, txo, optical ua haujlwm thiab carbohydrate zog, thiab muaj hydroxylation, antioxidant, txhim kho kev tiv thaiv kab mob thiab detoxification teebmeem hauv tib neeg lub cev. Kev lag luam yog feem ntau los ntawm biosynthesis (fermentation) txoj kev los npaj vitamin C, vitamin C yog siv rau hauv kev kho mob thiab zaub mov teb.
| Cov khoom siv lub cev thiab tshuaj lom neeg | 1. Tsos: dawb siv lead ua los yog crystalline hmoov. 2. Kev yaj: yooj yim yaj hauv dej, me ntsis yaj hauv ethanol, tsis yaj hauv ether, benzene, roj, thiab lwm yam. 3. Kev ua haujlwm ntawm qhov muag: Vitamin C muaj 4 lub isomers optical, thiab qhov kev sib hloov tshwj xeeb ntawm cov kua dej uas muaj L-ascorbic acid ntawm 0.10 g / ml yog + 20.5 ° - + 21.5 °. 4. Acid: Vitamin C muaj enediol base, uas yog acidic, feem ntau yog ib qho acid yooj yim uas tuaj yeem cuam tshuam nrog sodium bicarbonate los tsim cov ntsev sodium. 5. Cov khoom Carbohydrate: Cov qauv tshuaj ntawm vitamin C zoo ib yam li cov suab thaj, nrog rau 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 tsim xiav. 6. Cov yam ntxwv ntawm kev nqus ultraviolet: Vim muaj cov khoom sib txuas ua ke hauv cov vitamin C molecules, nws cov kua dilute muaj qhov nqus siab tshaj plaws ntawm 243 nm wavelength, thiab qhov nqus siab tshaj plaws yuav raug hloov mus rau 265 nm nyob rau hauv cov xwm txheej acidic lossis alkaline. 7. Kev txo qis: pawg enediol hauv cov vitamin yog qhov txo qis heev, ruaj khov hauv qhov chaw acidic, thiab yooj yim rhuav tshem hauv qhov kub, lub teeb, aerobic thiab alkaline ib puag ncig. Vitamin C yog oxidized los tsim cov qauv diketo-based ntawm dehydrovitamin C, dehydrovitamin C tuaj yeem tau txais tom qab hydrogenation txo qis ntawm vitamin C. Tsis tas li ntawd, hauv cov kua alkaline thiab cov kua qaub muaj zog, dehydrovitamin C tuaj yeem hydrolyzed ntxiv kom tau txais diketogulonic acid. |
| Kev ua haujlwm ntawm lub cev | 1. Hydroxylation Vitamin C koom nrog rau hauv cov tshuaj hydroxylation hauv tib neeg lub cev, uas muaj feem cuam tshuam nrog cov metabolism ntawm ntau yam tseem ceeb hauv tib neeg lub cev. Piv txwv li, vitamin C tuaj yeem koom nrog thiab txhawb nqa hydroxylation ntawm cov cholesterol rau hauv cov kua qaub bile; Txhim kho kev ua haujlwm sib xyaw ua ke oxidase; Nws koom nrog hauv kev ua haujlwm hydroxylase thiab txhawb nqa kev tsim cov amino acid neurotransmitters 5-hydroxytryptamine thiab norepinephrine. 2. Tshuaj tua kab mob Vitamin C muaj zog txo qis thiab yog cov tshuaj antioxidant zoo heev uas yaj hauv dej, uas tuaj yeem txo cov hydroxyl radicals, superoxides thiab lwm yam oxides hauv tib neeg lub cev, thiab tuaj yeem tshem tawm cov free radicals thiab tiv thaiv lipid peroxidation. 3. Txhawb kev tiv thaiv kab mob Lub luag haujlwm phagocytic ntawm leukocyte muaj feem cuam tshuam nrog cov vitamin hauv plasma. Cov nyhuv antioxidant ntawm vitamin C tuaj yeem txo qhov disulfide bond (-S - S -) hauv cov antibody 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. Tshem tawm cov tshuaj lom hauv lub cev Cov tshuaj vitamin C ntau ntau tuaj yeem ua rau cov hlau hnyav xws li Pb2 +, Hg2 +, Cd2 +, cov tshuaj lom kab mob, benzene thiab qee cov tshuaj lysins. Lub tshuab tseem ceeb yog raws li nram no: qhov muaj zog ntawm vitamin C tuaj yeem tshem tawm cov glutathione oxidized ntawm tib neeg lub cev, thiab tom qab ntawd tsim cov khoom sib xyaw nrog cov hlau hnyav kom raug tso tawm ntawm lub cev; Vim tias cov pa oxygen hauv C2 txoj haujlwm ntawm vitamin C raug them tsis zoo, vitamin C nws tus kheej kuj tuaj yeem ua ke nrog cov hlau ions thiab tawm ntawm lub cev los ntawm cov zis; Vitamin C txhim kho kev ua haujlwm ntawm enzyme (hydroxylation) los pab txhawb kev tshem tawm cov tshuaj lom thiab tshuaj. 5. Kev nqus thiab kev ua haujlwm ntawm lub cev Kev nqus cov vitamin C los ntawm kev noj zaub mov hauv tib neeg lub cev feem ntau yog kev thauj mus los hauv txoj hnyuv me me sab saud los ntawm tus neeg thauj khoom, thiab me me raug nqus los ntawm kev sib kis tsis siv neeg. Thaum kev noj vitamin C tsawg, yuav luag txhua yam tuaj yeem nqus tau, thiab thaum kev noj mus txog 500 mg / hnub, tus nqi nqus yuav poob qis txog li 75%. Cov vitamin C uas nqus tau yuav nkag mus rau hauv cov ntshav sai sai thiab nkag mus rau hauv cov nqaij thiab cov kabmob ntawm lub cev. Feem ntau cov vitamin C raug metabolized hauv tib neeg lub cev mus rau hauv oxalic acid, 2, 3-diketogulonic acid, lossis ua ke nrog sulfuric acid los tsim ascorbate-2-sulfuric acid thiab tso tawm hauv cov zis; Ib txhia ntawm nws raug tso tawm hauv cov zis. Qhov ntau ntawm cov vitamin C uas tso tawm hauv cov zis raug cuam tshuam los ntawm kev noj vitamin C, kev ua haujlwm ntawm lub raum, thiab qhov ntau ntawm kev nco qab khaws cia hauv lub cev. |
| Txoj kev khaws cia | Tsis txhob khaws cia nrog cov tshuaj oxidants muaj zog thiab alkalis, thiab khaws cia rau hauv lub thawv kaw uas muaj cov pa roj inert ntawm qhov kub qis. |
