Tabuleti Yodziwika Kwambiri ya Vitamini C Yowonjezera Chitetezo cha Anthu
Mafotokozedwe Akatundu
| Zogulitsa | Vitamini C |
| CAS | 50-81-7 |
| Maonekedwe | White crystal kapena ufa woyera wa crystalline |
| Kusungunuka | Kusungunuka m'madzi, kusungunuka pang'ono mu ethanol, osasungunuka mu etha, benzene, mafuta, etc. |
Vitamini C (Vitamini C), yemwenso amadziwika kuti Ascorbic acid (Ascorbic acid), mawonekedwe a molekyulu ndi C6H8O6, ndi polyhydroxyl pawiri yomwe ili ndi maatomu a kaboni 6, ndi vitamini yosungunuka m'madzi yofunikira kuti thupi lizigwira ntchito bwino komanso kagayidwe kachakudya. zochita za maselo.Maonekedwe a vitamini C oyera ndi kristalo woyera kapena ufa wonyezimira, womwe umasungunuka mosavuta m'madzi, kusungunuka pang'ono mu Mowa, osasungunuka mu etha, benzene, mafuta ndi zina. Vitamini C ali ndi acidic, kuchepetsa, kuwala komanso mphamvu zama carbohydrate. hydroxylation, antioxidant, kupititsa patsogolo chitetezo chamthupi ndi zotsatira za detoxification m'thupi la munthu.Makampani makamaka kudzera biosynthesis (yowotchera) njira kukonzekera vitamini C, vitamini C zimagwiritsa ntchito m'munda wa zachipatala ndi chakudya.
| Thupi ndi mankhwala katundu | 1. Maonekedwe: kristalo woyera kapena ufa wa crystalline. 2. Kusungunuka: kusungunuka mosavuta m'madzi, kusungunuka pang'ono mu ethanol, kusungunuka mu etha, benzene, mafuta, ndi zina zotero. 3. Kuwala kwa ntchito: Vitamini C ili ndi ma isomers a 4, ndipo kusinthasintha kwapadera kwa njira yamadzimadzi yokhala ndi L-ascorbic acid ya 0.10 g/ml ndi +20.5 °-+21.5 °. 4. Acid: Vitamini C imakhala ndi ediol base, yomwe imakhala ya acidic, yomwe imawonetsedwa ngati asidi osavuta omwe amatha kuchitapo kanthu ndi sodium bicarbonate kupanga mchere wa sodium. 5. Zakudya zama carbohydrate: Kapangidwe kake ka vitamini C ndi kofanana ndi shuga, wokhala ndi shuga, womwe umatha kukhala hydrolyzed ndi decarboxylated kupanga pentose pamaso , ndikupitilizabe kutaya madzi kuti apange, kuwonjezera pyrrole ndikuwotcha. 50 ºC idzatulutsa buluu. 6. Mawonekedwe a Ultraviolet mayamwidwe: Chifukwa cha kukhalapo kwa ma conjugated awiri omangika mu mamolekyu a vitamini C, njira yake yochepetsera imakhala ndi mayamwidwe apamwamba kwambiri pa 243 nm wavelength, ndipo kutalika kwa mayamwidwe ake kudzasinthidwa kukhala 265 nm pansi pa acidic kapena alkaline mikhalidwe. 7. Reducibility: gulu la enediol mu vitamini ndilochepa kwambiri, lokhazikika m'malo a acidic, ndipo limawonongeka mosavuta kutentha, kuwala, aerobic ndi alkaline chilengedwe.Vitamini C ndi okosijeni kuti apange diketo-based structure of dehydrovitamin C, dehydrovitamin C ingapezeke pambuyo pa kuchepa kwa hydrogenation kwa vitamini C. Komanso, mu njira ya alkaline ndi yankho lamphamvu la asidi, dehydrovitamin C ikhoza kuwonjezeredwa ndi hydrolyzed kuti ipeze diketogulonic acid. |
| Physiological ntchito | 1. Hydroxylation Vitamini C nawo hydroxylation anachita mu thupi la munthu, amene amagwirizana ndi kagayidwe zinthu zambiri zofunika mu thupi la munthu.Mwachitsanzo, vitamini C akhoza kutenga nawo mbali ndikulimbikitsa hydroxylation ya mafuta m'thupi mu bile acid;Kupititsa patsogolo ntchito yosakanikirana ya oxidase;Iwo amachita hydroxylase ndi kulimbikitsa synthesis wa amino acid neurotransmitters 5-hydroxytryptamine ndi norepinephrine. 2. Antioxidant Vitamini C imakhala ndi mphamvu yochepetsetsa komanso imakhala yabwino kwambiri yosungunuka m'madzi, yomwe imatha kuchepetsa ma hydroxyl radicals, superoxides ndi ma oxides ena omwe amagwira ntchito m'thupi la munthu, ndipo amatha kuchotsa ma radicals aulere ndikuletsa lipid peroxidation. 3. Limbikitsani chitetezo chokwanira Ntchito ya phagocytic ya leukocyte imagwirizana ndi kuchuluka kwa vitamini mu plasma.Mphamvu ya antioxidant ya vitamini C imatha kuchepetsa mgwirizano wa disulfide (-S - S -) mu antibody kuti sulfhydryl (-SH), ndiyeno kulimbikitsa kuchepa kwa cystine kukhala cysteine, ndipo pamapeto pake kulimbikitsa mapangidwe a chitetezo. 4. Chotsani poizoni Mlingo waukulu wa vitamini C ukhoza kuchitapo kanthu pa ayoni azitsulo zolemera monga Pb2+, Hg2+, Cd2+, poizoni wa bakiteriya, benzene ndi ma lysins ena amankhwala.Njira yayikulu ndi iyi: kuchepa kwamphamvu kwa vitamini C kumatha kuchotsa oxidized glutathione m'thupi la munthu, kenako kupanga zovuta ndi ayoni azitsulo zolemera kuti atulutsidwe m'thupi;Chifukwa mpweya wa C2 wa vitamini C umakhala woipa, vitamini C yokha imatha kuphatikizidwanso ndi ayoni achitsulo ndikuchotsedwa m'thupi kudzera mkodzo;Vitamini C kumawonjezera enzyme ntchito (hydroxylation) atsogolere detoxification wa ziphe ndi mankhwala. 5. Mayamwidwe ndi kagayidwe Mayamwidwe a vitamini C kudzera mukudya m'thupi la munthu amayenda mwachangu m'matumbo ang'onoang'ono kumtunda kwa matumbo ang'onoang'ono ndi transporter, ndipo pang'ono amatengeka ndi kufalikira kwapang'onopang'ono.Kudya kwa vitamini C kukakhala kochepa, pafupifupi zonse zimatha kuyamwa, ndipo pamene kudya kufika 500 mg / d, kuyamwa kumatsikira pafupifupi 75%.Vitamini C wotengedwa mwachangu amalowa m'magazi ndikulowa m'magulu osiyanasiyana a thupi. Vitamini C ambiri zimapukusidwa mu thupi la munthu mu asidi oxalic, 2, 3-diketogulonic asidi, kapena pamodzi ndi asidi sulfuric kupanga ascorbate-2-sulfuric asidi ndi excreted mu mkodzo;Zina mwa izo zimatuluka mumkodzo.Kuchuluka kwa vitamini C wotulutsidwa mumkodzo kumakhudzidwa ndi kudya kwa vitamini C, ntchito ya impso, ndi kuchuluka kwa kukumbukira kosungidwa m'thupi. |
| Njira yosungira | Pewani kusunga ndi ma okosijeni amphamvu ndi ma alkalis, ndipo sungani mu chidebe chosindikizidwa chodzaza ndi mpweya wopanda mpweya potentha kwambiri.

Ubwino Wathu
1.Tili ndi gulu la akatswiri komanso ogwira ntchito omwe angakwaniritse zosowa zanu zosiyanasiyana.
2.Mukhale ndi chidziwitso chochuluka komanso chidziwitso cha malonda muzinthu za mankhwala, ndipo khalani ndi kafukufuku wozama pakugwiritsa ntchito mankhwala ndi momwe mungawonjezere zotsatira zake.
3.Dongosololi ndi lomveka, kuchokera pakupanga mpaka kupanga, kuyika, kuyang'anira khalidwe, pambuyo-kugulitsa, ndi kuchokera ku khalidwe kupita kuntchito kuti zitsimikizire kukhutira kwa makasitomala.
4.Price mwayi.Pamaziko owonetsetsa kuti zinthu zili bwino, tidzakupatsani mtengo wabwino kwambiri kuti muthandizire kukulitsa zokonda zamakasitomala.
Ubwino wa 5.Transportation, mpweya, nyanja, nthaka, kufotokoza, onse ali ndi othandizira odzipereka kuti azisamalira.Ziribe kanthu kuti mukufuna mayendedwe otani, titha kuchita.
