History

Kufunika kwa vitamini C kwadziwika mwasayansi patadutsa zaka zambiri kulephera komanso matenda owopsa. (matenda omwe amabwera chifukwa chosowa vitamini C) adazunza anthu kwazaka zambiri, kufikira pomwe pamapeto pake adayesedwa kuti awachiritse. Odwala nthawi zambiri amakhala ndi zizindikilo monga zotupa, zotuluka m'kamwa, kutuluka magazi kambiri, pallor, kukhumudwa, ndi ziwalo pang'ono.

400 BC Hippocrates ndiye anali woyamba kufotokozera za matenda a scurvy.
Zima za 1556 - panali mliri wa matenda womwe udafalikira ku Europe konse. Ndi ochepa omwe amadziwa kuti kubuka kumeneku kumayambitsidwa ndi kuchepa kwa zipatso ndi ndiwo zamasamba m'miyezi yozizira iyi. Ngakhale uwu unali umodzi mwamatenda oyambilira amiseche, palibe kafukufuku wambiri amene wachitika kuti athetse matendawa. Jacques Cartier, wofufuza malo wodziwika, anazindikira mwachidwi kuti amalinyero ake, omwe amadya malalanje, mandimu ndi zipatso, sanapeze scurvy, ndipo omwe anali ndi matendawa adachira.
Mu 1747, a James Lind, dokotala waku Britain, adatsimikiza koyamba kuti pali ubale weniweni pakati pa zakudya ndi zochitika zamatenda. Pofuna kutsimikizira mfundo yake, adayambitsa madzi a mandimu kwa iwo omwe adawazindikira. Pambuyo pamiyeso ingapo, odwala adachiritsidwa.
Mu 1907, kafukufuku adawonetsa kuti pamene nkhumba za Guinea (imodzi mwa nyama zochepa zomwe zingatenge matendawa) idadwala matenda amiseche, kuchuluka kwa vitamini C kunawathandiza kuchira kwathunthu.
Mu 1917, kafukufuku wachilengedwe adachitika kuti adziwe zovuta zakudya.
Mu 1930 Albert Szent-Gyorgyi adatsimikizira izi hyaluronic acid, yomwe adatulutsa m'matumba a adrenal a nkhumba mu 1928, ali ndi mawonekedwe ofanana ndi vitamini C, omwe adatha kuwapeza ochuluka kuchokera ku tsabola wa belu.
Mu 1932, mu kafukufuku wawo wodziyimira pawokha, Heworth ndi King adakhazikitsa vitamini C.
Mu 1933, kuyesa koyambirira kunapangidwa kuti apange asidi ya ascorbic, yofanana ndi vitamini C wachilengedwe - gawo loyamba pakupanga mavitamini kuyambira 1935.
Mu 1937, Heworth ndi Szent-Gyorgyi adalandira Mphotho ya Nobel pazofufuza zawo za vitamini C.
Kuyambira 1989, kuchuluka kwa vitamini C patsiku kwakhazikitsidwa ndipo lero ndikwanira kuthana ndi scurvy.

Pali zinthu zopitilira 30,000 zokonda zachilengedwe, mitengo yowoneka bwino komanso kukwezedwa pafupipafupi, kosalekeza 5% kuchotsera ndi nambala yampikisano CGD4899, kutumiza kwaulere padziko lonse lapansi kulipo.

Zopindulitsa za vitamini C

Monga micronutrients ambiri, vitamini C imagwira ntchito zingapo. Ndi yamphamvu komanso yopanga zochitika zingapo zofunika. Imachita mbali yofunikira pakupanga collagen, chinthu chomwe chimapanga gawo lalikulu la malo athu ndi khungu. Popeza thupi silingathe kudzikonza lokha popanda kolajeni, kuchiritsa mabala kumadalira kuchuluka kwa vitamini C - ndichifukwa chake chimodzi mwazizindikiro za scurvy ndi zilonda zotseguka zomwe sizichira. Vitamini C imathandizanso thupi kuyamwa ndikugwiritsa ntchito (ndichifukwa chake kuchepa magazi kumatha kukhala chizindikiritso chamatenda, ngakhale anthu omwe amadya chitsulo chokwanira).

Kuphatikiza pa maubwino awa, vitamini C ndi antihistamine: imalepheretsa kutulutsidwa kwa neurotransmitter histamine, yomwe imayambitsanso kutupa chifukwa chotsatira. Ichi ndichifukwa chake scurvy nthawi zambiri imabwera ndi totupa, ndipo chifukwa chiyani kupeza vitamini C wokwanira kumathandiza kuthana ndi zovuta zina.

Vitamini C imalumikizananso ndi matenda ena osafalikira monga matenda amtima, komanso. Kafukufuku apeza kulumikizana pakati pa vitamini C ndi kuchepa kwa matenda amtima. Kafukufuku wosiyanasiyana wa mayesero a vitamini C awonetsa kusintha kwa endothelial ntchito ndi kuthamanga kwa magazi. Mavitamini C ambiri m'magazi amachepetsa chiopsezo chotenga 42%.

Posachedwa, akatswiri azachipatala ali ndi chidwi ndi zomwe zingapindule ndi vitamini C kudzera m'mitsempha yoteteza moyo wa odwala omwe amalandira chemotherapy. Kuchepetsa mavitamini C m'matumba a diso kumalumikizidwa ndi chiopsezo chowonjezeka chochitika, chomwe chimafala kwambiri kwa anthu achikulire. Kuphatikiza apo, pali umboni kuti anthu omwe amadya vitamini C wokwanira ali ndi chiopsezo chochepa chokhala ndi matenda a kufooka kwa mafupa. Vitamini C imathandizanso kwambiri kuthana ndi poyizoni wa lead, mwina kuteteza kuyamwa kwake m'matumbo ndikuthandizira kutuluka kwamikodzo.

European Scientific Committee on Nutrition, yomwe imapereka upangiri wasayansi kwa omwe amapanga mfundo, yatsimikizira kuti kusintha kwakukula kwaumoyo kwawoneka mwa anthu omwe adamwa vitamini C. Ascorbic acid imathandizira:

kuteteza zigawo zikuluzikulu za selo ku oxidation;
mapangidwe abwinobwino a kolajeni ndi magwiridwe antchito am'magazi, khungu, mafupa, chichereŵechereŵe, nkhama ndi mano;
kukonza mayamwidwe azitsulo kuchokera kumagwero azomera;
kugwira ntchito kwabwino kwa chitetezo chamthupi;

kusinthika kwa mtundu wosavuta wa vitamini E;
mkhalidwe wabwinobwino wamaganizidwe;
kuchepetsa kumva kutopa ndi kutopa.

Kuyesera kwa Pharmacokinetic kwawonetsa kuti kuchuluka kwa vitamini C m'magazi kumayang'aniridwa ndi njira zitatu zoyambirira: kuyamwa matumbo, kuyenda kwa minofu, ndi kubwezeretsanso kwaimpso. Poyankha kuchuluka kwa mavitamini C amchere, kuchuluka kwa vitamini C mu plasma kumawonjezeka kwambiri pamiyeso kuyambira 30 mpaka 100 mg / tsiku ndikufika pamlingo wokhazikika (kuyambira 60 mpaka 80 μmol / L) pamlingo wochokera 200 mpaka 400 mg / tsiku patsiku mwa achinyamata athanzi. Ntchito yokwanira 200% ya kuyamwa imawonedwa mukamamwa vitamini C pakamwa mpaka XNUMX mg nthawi imodzi. Mlingo wa plasma ascorbic acid ukafika pakukhwima, vitamini C yowonjezera imatulutsidwa mumkodzo. Makamaka, vitamini C kudzera m'mitsempha yodutsa m'matumbo imadutsa kuyamwa kwamatumbo kuti ma plasma okwera kwambiri a ascorbic acid akwaniritsidwe; Popita nthawi, kuchotsedwa kwa impso kumabwezeretsa vitamini C m'magawo oyambira a plasma.

Vitamini C wa chimfine

Vitamini C amatenga gawo lofunikira kwambiri m'thupi, lomwe limayambitsidwa thupi likakumana ndi matenda. Kafukufukuyu adapeza kuti kugwiritsa ntchito mankhwala ≥200 mg vitamini C owonjezera kumachepetsa kwambiri nthawi yazizira: mwa ana, nthawi yazizindikiro idachepetsedwa pafupifupi 14%, pomwe akulu idachepetsedwa ndi 8%. Kuphatikiza apo, kafukufuku pagulu la othamanga, skiers ndi asitikali omwe amaphunzitsa ku Arctic adawonetsa kuti kuchuluka kwa vitamini kuchokera ku 250 mg / tsiku kufika 1 g / tsiku kumachepetsa chimfine ndi 50%. Kafukufuku wambiri wogwiritsa ntchito wagwiritsa ntchito 1 g / tsiku. Chithandizo chinkayamba pakayamba zizindikiro, kuwonjezera kwa vitamini C sikunachepetse nthawi yayitali kapena kukula kwa matendawa, ngakhale pamlingo waukulu kuyambira 1 mpaka 4 g / tsiku^[38].

Momwe Vitamini C Amayambira

Popeza thupi la munthu silingathe kupanga vitamini C, tiyenera kuyiphatikiza pazakudya zathu za tsiku ndi tsiku. Vitamini C wazakudya wochepetsedwa wa ascorbic acid amalowetsedwa kudzera m'matumbo am'matumbo, kudzera m'matumbo ang'onoang'ono, poyenda mwachangu komanso kufalikira kosagwiritsa ntchito othandizira a SVCT 1 ndi 2.

Vitamini C sayenera kugayidwa asanatengedwe. Momwemo, pafupifupi 80-90% ya vitamini C yodyedwa imatengedwa kuchokera m'matumbo. Komabe, mphamvu ya kuyamwa kwa vitamini C imagwirizana mosagwirizana ndi kudya; Imafikira 80-90% yakuchita bwino ndikudya pang'ono kwa vitamini, koma izi zimatsika kwambiri ndi kudya tsiku lililonse kopitilira 1 gramu. Popeza kudya kwanthawi zonse kwa 30-180 mg / tsiku, kuyamwa nthawi zambiri kumakhala mu 70-90%, koma kumawonjezeka mpaka 98% ndikutsika kwambiri (osakwana 20 mg). Mosiyana ndi zimenezo, mukadyedwa mopitirira 1 g, kuyamwa kumakhala kosakwana 50%. Njira yonseyi ndi yofulumira kwambiri; thupi limatenga zimene limafunikira m’maola aŵiri, ndipo mkati mwa maola atatu kapena anayi gawo losagwiritsidwa ntchito limatuluka m’mwazi. Chilichonse chimachitika mofulumira kwambiri mwa anthu omwe amamwa mowa kapena ndudu, komanso m'mikhalidwe yovuta. Zinthu zina zambiri komanso zinthu zina zimatha kukulitsa kufunikira kwa thupi kwa vitamini C: kutentha thupi, matenda a virus, kumwa maantibayotiki, cortisone, aspirin ndi zoletsa zina zowawa, zotsatira za poizoni (mwachitsanzo, zinthu zamafuta, carbon monoxide) ndi zitsulo zolemera (kwa Mwachitsanzo, cadmium, lead, mercury).

M'malo mwake, kuchuluka kwa vitamini C m'maselo oyera amatha kukhala 80% ya vitamini C mu plasma. Komabe, thupi limakhala ndi mphamvu yochepa yosungira vitamini C. Malo osungira omwe amapezeka kwambiri ndi (pafupifupi 30 mg) ,,, maso, ndi. Vitamini C imapezekanso, ngakhale pang'ono, m'chiwindi, ndulu, mtima, impso, mapapo, kapamba, ndi minofu. Kuwonjezeka kwa mavitamini C a mavitamini C kumawonjezeka ndikudya kowonjezera, koma mpaka malire ena. Kudya kulikonse kwa 500 mg kapena kupitilira apo nthawi zambiri kumachotsedwa mthupi. Vitamini C wosagwiritsidwa ntchito amachotsedwa m'thupi kapena amatembenuzidwa kukhala dehydroascorbic acid. Makutidwe ndi okosijeniwa amapezeka makamaka m'chiwindi komanso impso. Vitamini C wosagwiritsidwa ntchito amatulutsidwa mkodzo.

Kafukufuku waposachedwa pa vitamini C

Asayansi aku Britain ochokera ku Yunivesite ya Salford apeza kuti kuphatikiza kwa vitamini C (ascorbic acid) ndi antibiotic doxycycline ndikothandiza polimbana ndi ma cell a khansa mu labotore. Pulofesa Michael Lisanti akufotokoza kuti: “Tikudziwa kuti maselo ena a khansa amayamba kugonjetsedwa ndi mankhwala pa chemotherapy ndipo tatha kumvetsetsa momwe izi zimachitikira. Tinkaganiza kuti maselo ena asintha komwe amapezako chakudya. Ndiye kuti, michere imodzi ikayamba kupezeka chifukwa cha chemotherapy, ma cell a khansa amapeza gwero lina la mphamvu. Kuphatikiza kwatsopano kwa vitamini C ndi doxycycline kumachepetsa izi, ndikupangitsa kuti maselo "afe ndi njala". Popeza zinthu zonse ziwiri sizomwe zili ndi poizoni zokha, zimatha kuchepetsa kwambiri zotsatira zake poyerekeza ndi mankhwala amwachikhalidwe.
Vitamini C yawonetsedwa kuti ndi othandiza polimbana ndi matenda amitsempha atachitidwa opaleshoni yamtima. Malinga ndi ofufuza ochokera ku Yunivesite ya Helsinki, kuchuluka kwa ma fibrillation atatha kugwira ntchito mwa odwala omwe adatenga vitamini C adatsika ndi 44%. Komanso, nthawi yomwe amakhala mchipatala atachitidwa opaleshoni idachepa mukamamwa vitamini. Tawonani kuti zotsatirazo zinali zowonekera pakulowetsa kwamankhwala m'thupi. Akatengedwa pakamwa, zotsatira zake zinali zochepa kwambiri.
Kafukufuku wopangidwa pa mbewa za labotale ndikukonzekera kwa chikhalidwe cha minyewa akuwonetsa kuti kumwa vitamini C pamodzi ndi mankhwala a chifuwa chachikulu kumachepetsa nthawi ya chithandizo. Zotsatira za kuyesaku zidasindikizidwa mu nyuzipepala ya Antimicrobial Agents ndi Chemotherapy ya American Society for Microbiology. Asayansi amachiza matendawa m'njira zitatu - ndi mankhwala a chifuwa chachikulu, makamaka vitamini C komanso kuphatikiza kwawo. Vitamini C analibe mphamvu zowonekera pakokha, koma kuphatikiza ndi mankhwala monga isoniazid ndi rifampicin, zidawongolera kwambiri minyewa yomwe ili ndi kachilomboka. Kutsekemera kwa zikhalidwe zamatenda kunachitika masiku asanu ndi awiri.

Kudzera mu mitochondria, poyankha kupsinjika, vitamini C imatumizidwa ku ziwalo zina zam'manja, monga ma chloroplast, komwe amafunikira ngati antioxidant komanso coenzyme pama kagwiritsidwe antchito amadzimadzi omwe amateteza chomeracho.

Vitamini C wosamalira ziweto

Vitamini C ndi wofunikira kwa nyama zonse. Ena mwa iwo, kuphatikiza anthu, anyani ndi nkhumba, amalandira vitamini kuchokera kunja. Zinyama zina zambiri, monga zoweta, nkhumba, akavalo, agalu, ndi amphaka, zimatha kupanga ascorbic acid kuchokera ku shuga m'chiwindi. Kuphatikiza apo, mbalame zambiri zimatha kupanga vitamini C m'chiwindi kapena impso. Chifukwa chake, kufunikira kwakugwiritsa ntchito sikunatsimikizidwe mu nyama zomwe zimatha kupanga payokha ascorbic acid. Komabe, matenda a scurvy, omwe ndi chizindikiro cha kuchepa kwa vitamini C, adanenedwa ndi ng'ombe ndi ng'ombe. Kuphatikiza apo, zowetchera zimatha kuchepa ndi mavitamini kuposa ziweto zina pamene ascorbic acid kaphatikizidwe imasokonekera chifukwa vitamini C imawonongeka mosavuta mu ramu. Ascorbic acid imagawidwa kwambiri m'matumba onse, nyama zomwe zimatha kupanga vitamini C komanso zomwe zimadalira vitamini wokwanira. Mwa nyama zoyesera, kuchuluka kwa vitamini C kumapezeka m'matumbo a pituitary ndi adrenal, milingo yayikulu imapezekanso m'chiwindi, ndulu, ubongo ndi kapamba.
