Poyambira kaphatikizidwe ka vitamini C ndikusankha makutidwe ndi okosijeni a shuga pawiri D-sorbit kupita ku L-sorbose pogwiritsa ntchito mabakiteriya a Acetobacter subboxidans.L-sorbose imasinthidwa kukhala L-ascorbic acid, yomwe imadziwika bwino kuti vitamini C.
Mchere wa sodium, potaziyamu, ndi calcium wa ascorbic acid amatchedwa ascorbates ndipo amagwiritsidwa ntchito ngati zosungira chakudya.Kupanga ascorbic asidi mafuta sungunuka, akhoza esterified.Esters of ascorbic acid ndi acids, monga palmitic acid kupanga ascorbyl palmitate ndi stearic acid kupanga ascorbic stearate, amagwiritsidwa ntchito ngati antioxidants muzakudya, mankhwala, ndi zodzoladzola.Ascorbic acid ndiyofunikiranso mu metabolism ya amino acid.Imateteza maselo ku kuwonongeka kwakukulu kwa ma free radicals, imathandizira kuyamwa kwachitsulo, ndipo ndiyofunikira panjira zambiri za metabolic.
Vitamini C ndi anti-oxidant yodziwika bwino.Zotsatira zake pakupanga kwaufulu pamene zimagwiritsidwa ntchito pakhungu pogwiritsa ntchito zonona sizinakhazikitsidwe bwino.Kugwira ntchito kwa mankhwala apamutu kumakayikiridwa chifukwa cha kusakhazikika kwa vitamini C (imachita ndi madzi ndikuwonongeka).Mitundu ina imanenedwa kukhala yokhazikika bwino m'madzi.Ma analogue opangidwa monga magnesium ascorbyl phosphate ndi ena mwa omwe amawonedwa kuti ndi othandiza kwambiri, chifukwa amakhala okhazikika.Mukawunika mphamvu yake yolimbana ndi kuwonongeka kopanda mphamvu potengera mphamvu yake yolumikizana ndi vitamini E, vitamini C imawala.Pamene vitamini E imakhudzidwa ndi ma free radicals, nawonso, amawonongeka ndi ma free radical omwe akumenyana nawo.Vitamini C amabwera kudzakonza kuwonongeka kwa free-radical mu vitamini E, kulola e kupitiriza ndi ntchito zake zowononga zopanda malire.Kafukufuku wam'mbuyomu adawonetsa kuti kuchuluka kwa vitamini C komwe kumagwiritsidwa ntchito pamutu kumateteza zithunzi, ndipo mwachiwonekere kukonzekera kwa vitamini komwe kumagwiritsidwa ntchito m'maphunzirowa kukana sopo ndi madzi, kuchapa, kapena kusisita kwa masiku atatu.Kafukufuku waposachedwa wasonyeza kuti vitamini C imawonjezera chitetezo ku kuwonongeka kwa UVB ikaphatikizidwa ndi mankhwala oteteza dzuwa a UVB.Zimenezi zingachititse munthu kuganiza kuti kuphatikiza ndi mankhwala oteteza ku dzuwa, vitamini C angathandize kuti pakhale chitetezo chokhalitsa padzuwa.Apanso, mgwirizano pakati pa mavitamini C ndi e ukhoza kubweretsa zotsatira zabwino kwambiri, chifukwa mwachiwonekere kuphatikiza zonsezi kumapereka chitetezo chabwino kwambiri ku kuwonongeka kwa UVB.Komabe, vitamini C ikuwoneka bwino kwambiri kuposa E poteteza ku kuwonongeka kwa UVA.Mfundo inanso n’njakuti kuphatikiza mavitamini C, e, ndi mafuta oteteza ku dzuwa kumapereka chitetezo chochuluka kuposa chitetezo chimene chimaperekedwa ndi chilichonse mwa zinthu zitatu zimene zimagwira ntchito zokha.Vitamini C imagwiranso ntchito ngati collagen biosynthesis regulator.Amadziwika kuti amawongolera zinthu zapakati pa cell colloidal monga collagen, ndipo zikapangidwa m'magalimoto oyenerera, zimatha kuwunikira khungu.Vitamini C akuti amatha kuthandiza thupi kulimbana ndi matenda opatsirana polimbitsa chitetezo cha mthupi.Pali umboni wina (ngakhale umatsutsana) kuti vitamini C imatha kudutsa m'zigawo za khungu ndikulimbikitsa machiritso mu minofu yowonongeka ndi kupsa kapena kuvulala.Choncho, amapezeka m'mafuta odzola ndi mafuta odzola omwe amagwiritsidwa ntchito potupa.Vitamini C ndi wotchuka kwambiri mu mankhwala oletsa kukalamba.Kafukufuku wamakono akuwonetsa zotheka anti-inflammatory properties komanso.
Physiological antioxidant.Coenzyme kwa angapo zochita hydroxylation;zofunika kuti collagen kaphatikizidwe.Amagawidwa kwambiri muzomera ndi nyama.Kusadya mokwanira kumabweretsa deficiency syndromes monga scurvy.Amagwiritsidwa ntchito ngati antimicrobial ndi antioxidant muzakudya.
