Ibyinshi bya Vitamine C Yokunywa Tablet yo Kongera Ubudahangarwa bwa muntu
Ibisobanuro ku bicuruzwa
| Ibicuruzwa | Vitamine C. |
| URUBANZA | 50-81-7 |
| Kugaragara | Ifu yera cyangwa ifu ya kirisiti yera |
| Gukemura | Gushonga mumazi, gushonga gake muri Ethanol, kudashonga muri ether, benzene, amavuta, nibindi |
Vitamine C (Vitamine C), alias Ascorbic aside (Acide Ascorbic), amata ya molekile ni C6H8O6, ni polyhydroxyl ivanze na atome 6 za karubone, ni vitamine ishonga amazi ikenewe kugirango ibungabunge imikorere isanzwe yumubiri na metabolike idasanzwe. reaction ya selile.Kugaragara kwa vitamine C yera ni ifu ya kirisiti yera cyangwa ifu ya kristaline, byoroshye gushonga mumazi, gushonga gake muri Ethanol, kutaboneka muri ether, benzene, amavuta, nibindi. Vitamine C ifite aside, igabanya, ibikorwa bya optique hamwe na karubone, kandi ifite hydroxylation, antioxydeant, kongera ubudahangarwa n'ingaruka zo kwangiza umubiri wumuntu.Inganda zikoreshwa cyane cyane muburyo bwa biosynthesis (fermentation) yo gutegura vitamine C, vitamine C ikoreshwa cyane mubuvuzi no mubiribwa.
| Imiterere yumubiri nubumara | 1. Kugaragara: ifu yera ya kirisiti cyangwa ifu ya kristu. 2. Gukemuka: gushonga byoroshye mumazi, gushonga gake muri Ethanol, kudashonga muri ether, benzene, amavuta, nibindi. 3. Igikorwa cyiza: Vitamine C ifite isomeri 4 optique, kandi kuzenguruka kwumuti wamazi urimo aside L-ascorbic ya 0,10 g / ml ni +20.5 ° - + 21.5 °. 4. Acide: Vitamine C ifite base ya enediol, irimo aside, muri rusange igaragara nka acide yoroshye ishobora gukora hamwe na sodium bicarbonate kugirango itange umunyu wa sodium. 5. Imiterere ya Carbohydrate: Imiterere yimiti ya vitamine C isa niy'isukari, hamwe nisukari, ishobora kuba hydrolyz na decarboxylated kugirango itange pentose ihari, kandi ikomeza gutakaza amazi kugirango itange umusaruro, wongere pyrrole no gushyushya 50 ºC izatanga ubururu. 6. Ibiranga Ultraviolet: Bitewe no kuba hari imigozi ibiri ihujwe na molekile ya vitamine C, igisubizo cyayo cya dilute gifite uburyo bwinshi bwo kwinjirira kuri 243 nm yumurambararo wa nm, kandi uburebure bwikwirakwizwa ryinshi buzahindurwa kuri 265 nm mugihe cya acide cyangwa alkaline. 7. Kugabanuka: itsinda rya enediol muri vitamine riragabanuka cyane, rihamye mubidukikije bya acide, kandi ryangirika byoroshye mubushyuhe, urumuri, aerobic na alkaline.Vitamine C ihindurwamo okiside kugirango itange imiterere ishingiye kuri diketo ya dehydrovitamine C, dehydrovitamine C irashobora kuboneka nyuma yo kugabanya hydrogène igabanya vitamine C. Byongeye kandi, mugisubizo cya alkaline hamwe nigisubizo gikomeye cya aside, dehydrovitamine C irashobora kongera hydrolyz kugirango ibone aside diketogulonic. |
| Imikorere ya physiologiya | 1. Hydroxylation Vitamine C igira uruhare muri hydroxylation reaction mu mubiri w'umuntu, ifitanye isano na metabolism y'ibintu byinshi by'ingenzi mu mubiri w'umuntu.Kurugero, vitamine C irashobora kugira uruhare no guteza imbere hydroxylation ya cholesterol muri acide;Gutezimbere ibikorwa bivanze nibikorwa bya okiside;Ifite uruhare muri hydroxylase kandi iteza imbere synthesis ya amino acide neurotransmitters 5-hydroxytryptamine na norepinephrine. 2. Antioxydants Vitamine C ifite kugabanuka gukomeye kandi ni antioxydants nziza cyane yo gushonga amazi, ishobora kugabanya hydroxyl radicals, superoxide nizindi oxyde ikora mumubiri wumuntu, kandi irashobora gukuraho radicals yubuntu kandi ikarinda lipide peroxidisation. 3. Ongera ubudahangarwa Imikorere ya fagocytike ya leukocyte ifitanye isano na vitamine muri plasma.Ingaruka ya antioxydeant ya vitamine C irashobora kugabanya isano ya disulfide (-S - S -) muri antibody kuri sulfhydryl (-SH), hanyuma igateza imbere kugabanuka kwa cystine kuri sisitemu, hanyuma bigateza imbere gukora antibodies. 4. Kwangiza Ingano nini ya vitamine C irashobora gukora kuri ion ziremereye nka Pb2 +, Hg2 +, Cd2 +, uburozi bwa bagiteri, benzene na lysine zimwe na zimwe.Uburyo nyamukuru nuburyo bukurikira: kugabanuka gukomeye kwa vitamine C birashobora gukuraho glutathione ya okiside mu mubiri wumuntu, hanyuma igakora urwego rugizwe na ion zicyuma ziremereye zisohoka mumubiri;Kubera ko ogisijeni iri muri C2 ya vitamine C yishyurwa nabi, vitamine C ubwayo irashobora kandi guhuzwa na ion z'icyuma hanyuma igasohoka mu mubiri ikoresheje inkari;Vitamine C yongera ibikorwa bya enzyme (hydroxylation) kugirango byorohereze uburozi nibiyobyabwenge. 5. Absorption na metabolism Kwinjira kwa vitamine C binyuze mu gufata ibiryo mu mubiri w'umuntu ni ubwikorezi bukora mu mara mato yo hejuru n'umuntu utwara abantu, kandi umubare muto ukoreshwa no gukwirakwiza pasiporo.Iyo gufata vitamine C ari bike, hafi ya byose birashobora kwinjizwa, kandi iyo gufata bigeze kuri mg / d 500, igipimo cyo kwinjira kizagabanuka kugera kuri 75%.Vitamine C yinjiye izahita yinjira mu maraso kandi yinjire mu ngingo zitandukanye no mu ngingo z'umubiri. Vitamine C nyinshi ihindurwa mu mubiri w'umuntu ikabamo aside ya oxyde, 2, 3-diketogulonike, cyangwa igahuzwa na aside sulfurike ikora acorbate-2-sulfurike ikasohoka mu nkari;Bimwe muri byo bisohoka mu nkari.Ingano ya vitamine C isohoka mu nkari iterwa no gufata vitamine C, imikorere y'impyiko, hamwe n'ububiko bwibitse mu mubiri. |
| Uburyo bwo kubika | Irinde kubika hamwe na okiside ikomeye na alkalis, kandi ubike mu kintu gifunze cyuzuyemo imyuka ya inert ku bushyuhe buke.
