Igihagararo Ihamye.Birashobora kuba byoroheje cyangwa byoroshye ikirere.Ntibishobora gukoreshwa na okiside, alkalies, fer, umuringa.

 

Intangiriro yo gusanisha vitamine C ni uguhitamo okiside yisukari yisukari D-sorbit kuri L-sorbose ukoresheje bacteri za Acetobacter suboxidans.L-sorbose noneho ihinduka L-ascorbic aside, izwi cyane nka vitamine C.

Sodium, potasiyumu, na calcium umunyu wa acide acorbike bita ascorbates kandi bikoreshwa mu kubika ibiryo.Gukora aside irike ya acorbike, irashobora gushirwa.Esters ya acide acide na acide, nka acide palmitike kugirango ibe palmitate ya ascorbyl na acide stearic kugirango ibe asorbike stearate, ikoreshwa nka antioxydants mubiribwa, imiti, no kwisiga.Acide ya Ascorbic nayo ni ngombwa muri metabolism ya acide amine.Ifasha kurinda selile kwangirika kwubusa, ifasha kwinjiza fer, kandi ni ngombwa mubikorwa byinshi byo guhinduranya.

Vitamine C ni anti-okiside izwi cyane.Ingaruka zayo muburyo bwisanzuye-radical iyo ikoreshejwe cyane kuruhu hakoreshejwe amavuta ntabwo byagaragaye neza.Imikorere yibikorwa byingenzi yaribazwe kubera vitamine C idahungabana (ifata amazi kandi ikangirika).Imiterere imwe nimwe ivuga ko ifite umutekano muke muri sisitemu yamazi.Ibigereranyo bya sintetike nka magnesium ascorbyl fosifate biri mubifatwa nkibyiza, kuko bikunda guhagarara neza.Iyo usuzumye ubushobozi bwayo bwo kurwanya ibyangiritse byubusa bitewe ningaruka zayo hamwe na vitamine e, vitamine C irabagirana.Nkuko vitamine e ikora hamwe na radical yubuntu, nayo, yangijwe na radical yubusa irwana.Vitamine C ije gusana ibyangiritse byubusa muri vitamine e, bituma e ikomeza ninshingano zayo zo gusiba ubusa.Ubushakashatsi bwashize bwerekanye ko vitamine C ikoreshwa cyane na vitamine C ikoreshwa cyane, kandi bigaragara ko gutegura vitamine yakoreshejwe muri ubwo bushakashatsi byananiye isabune n'amazi, gukaraba, cyangwa gukaraba iminsi itatu.Ubushakashatsi burenzeho bwerekanye ko vitamine C yongerera uburinzi kwangirika kwa uVB iyo ihujwe n’imiti yizuba ya uVB.Ibi byatuma umuntu yemeza ko afatanije nizuba risanzwe ryizuba ryizuba, vitamine C irashobora gutuma izuba riramba kandi rirambye.Na none kandi, ubufatanye hagati ya vitamine C na e bushobora gutanga umusaruro ushimishije, kuko bigaragara ko guhuza byombi bitanga uburinzi bwiza cyane bwo kwangirika kwa uVB.Nyamara, vitamine C isa neza cyane kuruta e mukurinda kwangirika kwa uVA.Undi mwanzuro ni uko guhuza vitamine C, e, hamwe nizuba ryizuba bitanga uburinzi burenze ubwinshi bwuburinzi butangwa na kimwe mubintu bitatu bikora wenyine.Vitamine C nayo ikora nka kolagen biosynthesis.Birazwiho kugenzura ibintu bigize ingirabuzimafatizo nka kolagene, kandi iyo bikozwe mu binyabiziga bikwiye, bishobora kugira ingaruka zo kumurika uruhu.Vitamine C ngo ishobora gufasha umubiri gukomera ku ndwara zanduza ukomeza ubudahangarwa bw'umubiri.Hariho ibimenyetso bimwe (nubwo bigibwaho impaka) byerekana ko vitamine C ishobora kunyura mubice byuruhu kandi igatera gukira mubice byangijwe no gutwikwa cyangwa gukomeretsa.Iraboneka rero, mumavuta yo gutwika hamwe na cream ikoreshwa mugukuramo.Vitamine C irazwi cyane mu bicuruzwa birwanya gusaza.Ubushakashatsi bugezweho bwerekana uburyo bushoboka bwo kurwanya inflammatory.

Antioxydants ya physiologique.Coenzyme kubintu byinshi bya hydroxylation reaction;bikenewe kuri synthesis ya kolagen.Ikwirakwizwa cyane mu bimera no mu nyamaswa.Gufata bidahagije bivamo syndrome de sisitemu nka scurvy.Ikoreshwa nka anticicrobial na antioxidant mubiribwa.
