Ivithamin C(I-Vitamin C), i-alias Ascorbic acid (i-Ascorbic acid), i-molecular formula yi-C6H8O6, i-polyhydroxyl ikhompawundi equlethe i-athomu ze-carbon ezi-6, yivithamin enyibilikayo emanzini eyimfuneko ukuze kugcinwe umsebenzi oqhelekileyo womzimba kunye nesenzo esingaqhelekanga se-metabolic reaction. iiseli.Imbonakalo yevithamin C esulungekileyo yikristale emhlophe okanye icrystalline powder, enyibilika lula emanzini, inyibilika kancinane kwi ethanol, ayinyibiliki kwi ether, benzene, grease, njalo njalo. Ivithamin C ineasidi, iyancitshiswa, iyakwazi ukusebenza kunye neempawu zecarbohydrate, kwaye i-hydroxylation, i-antioxidant, ukuphuculwa kwe-immune kunye nemiphumo ye-detoxification emzimbeni womntu.Ishishini ikakhulu ngokusebenzisa biosynthesis (fermentation) indlela yokulungisa ivithamin C, ivithamin C isetyenziswa ikakhulu kwintsimi yezonyango kunye nentsimi ukutya.
Iimpawu zomzimba kunye neekhemikhali | 1. Ukubonakala: ikristale emhlophe okanye i-crystalline powder. 2. Ukunyibilika: ukunyibilika ngokulula emanzini, ukunyibilika kancinci kwi-ethanol, ukunyibilika kwi-ether, benzene, igrisi, njl. 3. Umsebenzi we-Optical: I-Vitamin C ine-4 isomers ye-optical, kunye nokujikeleza okuthe ngqo kwesisombululo samanzi esine-L-ascorbic acid ye-0.10 g / ml yi-20.5 ° - + 21.5 °. 4. I-Acid: I-Vitamin C inesiseko se-enediol, esine-acidic, esibonakaliswa ngokubanzi njenge-asidi elula enokusabela nge-sodium bicarbonate ukuvelisa ityuwa ye-sodium. 5. Iimpawu zeCarbohydrate: Ukwakhiwa kweekhemikhali zevithamini C kufana neswekile, kunye neempawu zeswekile, ezinokuhlanjululwa nge-hydrolyzed kunye ne-decarboxylated ukuvelisa i-pentose phambi kobukho , kwaye uqhubeke ulahlekelwa ngamanzi ukuvelisa, ukongeza i-pyrrole kunye nokufudumeza. 50 ºC uya kuvelisa blue. 6. Iimpawu zokuxilwa kwe-Ultraviolet: Ngenxa yobukho be-conjugated double bonds kwii-molecule ze-vitamin C, isisombululo saso se-dilute sine-absorption ephezulu kwi-243 nm wavelength, kwaye ubuninzi be-absorption wavelength buya kutshintshwa kwi-265 nm phantsi kweemeko ze-acidic okanye i-alkaline. 7. Ukunciphisa: iqela le-enediol kwi-vitamin liyancipha kakhulu, lizinzile kwindawo ene-acidic, kwaye litshatyalaliswe ngokulula ekushiseni, ukukhanya, i-aerobic kunye ne-alkaline.I-Vitamin C i-oxidized ukuvelisa i-diketo-based structure ye-dehydrovitamin C, i-dehydrovitamin C inokufumaneka emva kokunciphisa i-hydrogenation ye-vitamin C. Ukongezelela, kwisisombululo se-alkaline kunye nesisombululo esinamandla se-asidi, i-dehydrovitamin C inokuqhutyelwa ngakumbi nge-hydrolyzed ukufumana i-diketogulonic acid. |
Umsebenzi wePhysiology | 1. I-Hydroxylation I-Vitamin C ithatha inxaxheba kwi-hydroxylation reaction emzimbeni womntu, ehambelana ne-metabolism yezinto ezininzi ezibalulekileyo kumzimba womntu.Ngokomzekelo, i-vitamin C inokuthatha inxaxheba kwaye ikhuthaze i-hydroxylation ye-cholesterol kwi-bile acids;Ukuphucula umsebenzi odibeneyo we-oxidase;Ibandakanyeka kwisenzo se-hydroxylase kwaye ikhuthaza ukuhlanganiswa kwe-amino acid neurotransmitters 5-hydroxytryptamine kunye ne-norepinephrine. 2. I-Antioxidant I-Vitamin C ine-reducibility enamandla kwaye i-antioxidant enhle kakhulu e-soluble yamanzi, enokunciphisa i-hydroxyl radicals, i-superoxides kunye nezinye i-oxides ezisebenzayo emzimbeni womntu, kwaye inokususa i-radicals yamahhala kunye nokukhusela i-lipid peroxidation. 3. Khulisa ukhuseleko Umsebenzi we-phagocytic we-leukocyte unxulumene nenqanaba levithamini kwi-plasma.Impembelelo ye-antioxidant ye-vitamin C inokunciphisa i-disulfide bond (-S - S -) kwi-antibody kwi-sulfhydryl (-SH), kwaye emva koko ikhuthaze ukunciphisa i-cystine kwi-cysteine, kwaye ekugqibeleni ikhuthaze ukubunjwa kwama-antibodies. 4. Ukukhupha ityhefu Iidosi ezinkulu zevithamin C zinokusebenza kwii-ion zentsimbi enzima ezifana nePb2+, Hg2+, Cd2+, ityhefu yebhaktiriya, ibenzene kunye nelysins yeziyobisi.Indlela ephambili yile ilandelayo: ukunciphisa okunamandla kwe-vitamin C kunokususa i-glutathione ene-oxidized emzimbeni womntu, kwaye emva koko yenze i-complex kunye ne-ion zetsimbi enzima ukuba ikhutshwe emzimbeni;Ngenxa yokuba i-oksijini kwindawo ye-C2 ye-vitamin C ihlawuliswa kakubi, i-vitamin C ngokwayo inokudibaniswa ne-ion yensimbi kwaye ikhutshwe emzimbeni ngomchamo;I-Vitamin C iphakamisa umsebenzi we-enzyme (i-hydroxylation) ukuququzelela ukuchithwa kweetyhefu kunye neziyobisi. 5. Ukufunxa kunye nemetabolism Ukufunxwa kwevithamin C ngokutya kumzimba womntu ikakhulu kuthutho olusebenzayo kumathumbu amancinci angasentla ngumthuthi, kwaye isixa esincinci sifunxwa yi-passive diffusion.Xa ukuthathwa kwe-vitamin C kuphantsi, phantse yonke into inokuthatyathwa, kwaye xa i-intake ifikelela kwi-500 mg / d, izinga lokufunxa liya kuhla malunga ne-75%.I-vitamin C efunxayo iya kungena ngokukhawuleza kumjikelezo wegazi kwaye ingene kwizicubu ezahlukeneyo kunye namalungu omzimba. Uninzi lwe-vitamin C luxutywe emzimbeni womntu kwi-oxalic acid, i-2, i-3-diketogulonic acid, okanye idibaniswe ne-asidi ye-sulfuric ukwenza i-ascorbate-2-sulfuric acid kunye ne-excreted kumchamo;Enye ikhutshelwa emchameni.Isixa sevithamin C ekhutshwe kumchamo sichatshazelwa yi-vitamin C, ukusebenza kwezintso, kunye nenani lememori egcinwe emzimbeni. |
Indlela yokugcina | Kuphephe ukugcina nge-oxidants eyomeleleyo kunye neealkali, kwaye ugcine kwisikhongozelo esitywiniweyo esizaliswe ziigesi ezingasebenziyo kumaqondo obushushu aphantsi. |
