Piritsi Rinonyanya Kutsenga reVitamin C reKuvandudza Dziviriro Yemuviri Yevanhu
Tsananguro yeChigadzirwa
| Chigadzirwa | Vhitamini C |
| CAS | 50-81-7 |
| Chitarisiko | Upfu hwekristaro chena kana chena hwekristaro |
| Kunyunguduka | Inonyungudika mumvura, inonyungudika zvishoma mu ethanol, hainyungudike mu ether, benzene, grisi, nezvimwewo |
Vhitamini C (Vhitamini C), inozivikanwawo seAscorbic acid (Ascorbic acid), fomura yemamorekuru inonzi C6H8O6, imusanganiswa wepolyhydroxyl une maatomu matanhatu ekabhoni, ivhitamini inonyungudika mumvura inodiwa kuchengetedza mashandiro emuviri uye mashandiro asina kujairika emasero. Kuonekwa kwevhitamini C yakachena ikristalo chena kana kristalo upfu, hunonyungudika nyore nyore mumvura, hunonyungudika zvishoma muethanol, haunyungudike mu ether, benzene, grisi, nezvimwewo. Vhitamini C ine acidic, reduction, optical activity uye carbohydrate properties, uye ine hydroxylation, antioxidant, immune enhancement uye detoxification effects mumuviri wemunhu. Indasitiri inonyanya kushandisa biosynthesis (fermentation) nzira yekugadzira vhitamini C, vhitamini C inonyanya kushandiswa mumunda wekurapa uye mumunda wezvekudya.
| Hunhu hwemuviri nemakemikari | 1. Chitarisiko: kristalo chena kana upfu hwekristaro. 2. Kunyungudika: inonyungudika nyore mumvura, inonyungudika zvishoma mu ethanol, hainyungudike mu ether, benzene, grisi, nezvimwewo. 3. Kushanda kweOptical: Vhitamini C ine maisomers mana e optical, uye kutenderera kwemvura ine L-ascorbic acid ye0.10 g/ml ndeye +20.5 °-+21.5 °. 4. Asidhi: Vhitamini C ine enediol base, iyo ine acid, inowanzoonekwa seasidhi iri nyore inogona kusangana nesodium bicarbonate kugadzira sodium salt. 5. Hunhu hwemakabhohaidhiretsi: Maumbirwo emakemikoro evhitamini C akafanana nehunhu hweshuga, hunhu hweshuga, iyo inogona kunyungudutswa uye kubudiswa mucarboxylated kuti ibudise pentose iripo, uye inoramba ichirasikirwa nemvura kuti ibudise, kuwedzera pyrrole uye kupisa kusvika ku50 ºC kuchaita bhuruu. 6. Hunhu hwekunyudzwa kweUltraviolet: Nekuda kwekuvapo kwezvisungo zviviri zvakasanganiswa mumamorekuru evhitamini C, mushonga wayo we dilute une mukana wepamusoro wekunyudzwa pa243 nm wavelength, uye mukana wepamusoro wekunyudzwa uchaderedzwa kusvika 265 nm kana paine acidic kana alkaline. 7. Kugona kuderedzwa: boka re enediol riri muvhitamini rinogona kuderedzwa zvakanyanya, rakagadzikana munzvimbo ine acid, uye rinoparadzwa zviri nyore munzvimbo dzinopisa, dzakareruka, dzine aerobic uye dzine alkaline. Vhitamini C inogadziriswa kuti igadzire chimiro che dehydrovitamin C chakavakirwa pa diketo, dehydrovitamin C inogona kuwanikwa mushure mekuderedzwa kwe hydrogenation yevhitamini C. Pamusoro pezvo, mune alkaline solution uye strong acid solution, dehydrovitamin C inogona kuwedzeredzwa kuti iwane diketogulonic acid. |
| Basa remuviri | 1. Kunyungudutsa kwemvura mumuviri Vhitamini C inobatana nekuita kwehydroxylation mumuviri wemunhu, izvo zvine chekuita nekushandiswa kwezvinhu zvakawanda zvakakosha mumuviri wemunhu. Semuenzaniso, vhitamini C inogona kutora chikamu mukuwedzera hydroxylation yecholesterol kuita bile acids; Kuvandudza mashandiro e mixed function oxidase; Inobatanidzwa mukuita kwehydroxylase uye inokurudzira kugadzirwa kweamino acid neurotransmitters 5-hydroxytryptamine uye norepinephrine. 2. Antioxidant Vhitamini C inogona kudzikiswa zvakanyanya uye iantioxidant yakanaka kwazvo inonyungudika mumvura, iyo inogona kuderedza hydroxyl radicals, superoxides nedzimwe oxides dzinoshanda mumuviri wemunhu, uye inogona kubvisa free radicals nekudzivirira lipid peroxidation. 3. Wedzera dziviriro yemuviri Basa rema "phagocyte" rine chekuita nehuwandu hwevhitamini muropa. Vitamin C inogona kuderedza disulfide bond (-S-S-) mu "antibody to sulfhydryl" (-SH), uye yobva yawedzera kudzikira kwe cystine kuita cysteine, uye pakupedzisira inokurudzira kuumbwa kwe "antibodies". 4. Bvisa chepfu mumuviri Madhigirii akawanda evhitamini C anogona kushanda pamaion ane simbi dzakakora akadai sePb2+, Hg2+, Cd2+, chepfu dzebhakitiriya, benzene nedzimwe drug lysins. Maitiro makuru ndeaya anotevera: kuderedzwa kwakasimba kwevhitamini C kunogona kubvisa glutathione yakasanganiswa mumuviri wemunhu, uye wobva wagadzira complex ine maion ane simbi dzakakora kuti abudiswe mumuviri; Nekuti okisijeni iri panzvimbo yevhitamini C yeC2 ine charge yakaipa, vhitamini C pachayo inogonawo kusanganiswa nemaion esimbi uye kuburitswa mumuviri kuburikidza ne weti; vhitamini C inowedzera mashandiro ema enzyme (hydroxylation) kuti zvive nyore kubvisa chepfu nemishonga. 5. Kunyudzwa uye kugadzirwa kwemuviri Kupinda kwevhitamini C mumuviri wemunhu kuburikidza nechikafu chinodyiwa kunonyanya kuendeswa muura hwepamusoro nechinhu chinotakurwa, uye huwandu hushoma hunotorwa nekupararira kwemuviri. Kana vhitamini C ishoma, inenge yese inogona kutorwa, uye kana ikasvika 500 mg/zuva, mwero wekupinza kwevhitamini C unoderera kusvika pa75%. Vhitamini C inotorwa inokurumidza kupinda muropa uye inopinda munyama dzakasiyana-siyana nenhengo dzemuviri. Vhitamini C yakawanda inogadzirwa mumuviri wemunhu kuita oxalic acid, 2, 3-diketogulonic acid, kana kusanganiswa nesulfuric acid kugadzira ascorbate-2-sulfuric acid uye inoburitswa muweti; Imwe yacho inoburitswa muweti. Huwandu hwevhitamini C inoburitswa muweti hunokanganiswa nekudya kwevhitamini C, mashandiro eitsvo, uye huwandu hwendangariro dzakachengetwa mumuviri. |
| Nzira yekuchengetedza | Dzivisa kuchengeta pamwe chete nemakemikari ane simba uye alkali, uye chengeta mumudziyo wakavharwa wakazadzwa nemagasi asina simba patembiricha yakaderera.

Zvakanakira Zvedu
1.Tine timu yehunyanzvi uye inoshanda zvakanaka inogona kusangana nezvinodiwa zvako zvakasiyana-siyana.
2. Iva neruzivo rwakakura uye ruzivo rwekutengesa muzvigadzirwa zvemakemikari, uye uve netsvakiridzo yakadzama pakushandiswa kwezvigadzirwa uye kuti ungawedzera sei mhedzisiro yazvo.
3. Sisitimu iyi yakanaka, kubva pakugovera kusvika pakugadzira, kurongedza, kuongororwa kwemhando, mushure mekutengesa, uye kubva pamhando kusvika pabasa kuti ive nechokwadi chekugutsikana kwevatengi.
4. Mutengo wakanaka. Tichifunga nezvehunhu hwezvinhu, tichakupai mutengo wakanakisisa kuti tibatsire kuwedzera zvido zvevatengi.
5. Zvakanakira zvekufambisa, mhepo, gungwa, nyika, nekukurumidza, zvese zvine vamiririri vakazvipira kuzvitarisira. Hazvina mhosva kuti nzira ipi yekufambisa yaunoda kushandisa, isu tinogona kuzviita.
