Whakaahuatanga Hua
| Hua | Huaora C |
| CAS | 50-81-7 |
| Te ahua | Kiriata ma, paura tioata ma ranei |
| Wairewa | Wairewa i roto i te wai, paku wairewa i roto i te waihā, karekau e rewa i roto i te ether, benzene, hinu, etc |
Huaora C (Vitamin C), he waikawa Ascorbic (Ascorbic acid), ko te tauira ngota ko C6H8O6, he puhui polyhydroxyl kei roto e 6 nga ngota waro, he huaora wairewa-wai e tika ana hei pupuri i te mahi a-tinana o te tinana me te rereke o te tinana. tauhohenga o nga pūtau.Ko te ahua o te huaora C parakore he karaihe ma, he paura tioata ranei, he ngawari ki te wairewa i roto i te wai, he iti te wairewa i roto i te waihano, he kore e rewa i roto i te ether, benzene, hinu, me etahi atu. Ko te Huaora C he waikawa, he whakaheke, he mahi whatu me nga taonga warowaiha, a he te hydroxylation, te antioxidant, te whakarei ake i te aukati me nga paanga o te whakakore i roto i te tinana o te tangata.Ko te nuinga o te ahumahi na roto i te biosynthesis (fermentation) tikanga ki te whakarite huaora C, te nuinga o te huaora C e whakamahia ana i roto i te mara rongoa me te mara kai.
| Ngā āhuatanga ā-tinana, matū hoki | 1. Te ahua: te karaihe ma, te paura karaihe ranei. 2. Wairewa: he ngawari te whakarewa ki te wai, he iti te wairewa i roto i te waihano, he kore e rewa i roto i te etera, te benzene, te hinu, aha atu. 3. Mahi matakite: E 4 nga inehanga whatu a Huaora C, a ko te hurihanga motuhake o te wairewa wai kei roto te waikawa L-ascorbic o 0.10 g/ml he +20.5 °-+21.5 °. 4. Waikawa: Kei te Huaora C te turanga enediol, he waikawa, ka kitea hei waikawa ngawari ka tauhohe ki te konutai bicarbonate hei whakaputa i te tote konutai. 5. Nga taonga warowaiha: Ko te hanganga matū o te huaora C he rite ki te huka, me nga ahuatanga o te huka, ka taea te whakamaarama me te whakakore i te warowaihā ki te whakaputa pentose i mua i te aroaro , ka ngaro tonu te wai ki te whakaputa, te taapiri i te pyrrole me te whakamahana ki te 50ºC ka puta he kahurangi. 6. Ko nga ahuatanga o te tango i te Ultraviolet: Na te mea kei te noho tahi nga hononga takirua i roto i nga ngota ngota huaora C, ko tana otinga waimeha he nui te whakauru ki te 243 nm te roangaru, a ka huri te roangaru whakauru ki te 265 nm i raro i nga tikanga waikawa, kawakore ranei. 7. Reducibility: Ko te roopu enediol i roto i te huaora he tino whakaheke, he pumau i roto i te taiao waikawa, me te ngawari ki te whakangaro i te wera, te marama, te aerobic me te taiao.Ko te Huaora C te oxidized ki te whakaputa i te hanganga diketo-e hāngai ana o dehydrovitamin C, dehydrovitamin C ka taea te whiwhi i muri i te whakaiti hauwaitanga o te huaora C. I tua atu, i roto i te otinga kawakore me te otinga waikawa kaha, dehydrovitamin C e taea te hydrolyzed atu ki te whiwhi waikawa diketogulonic. |
| Te mahi tinana | 1. Te hauwai Ka whai wāhi te Huaora C ki roto i te tauhohenga hydroxylation i roto i te tinana o te tangata, e pa ana ki te whakawhitinga o te maha o nga matū nui i roto i te tinana o te tangata.Hei tauira, ka taea e te huaora C te whakauru me te whakatairanga i te hydroxylation o te cholesterol ki roto i nga waikawa papa;Te whakarei ake i te mahi whakauru oxidase mahi;Kei roto i te mahi hydroxylase me te whakatairanga i te whakahiato o te waikawa amino neurotransmitters 5-hydroxytryptamine me te norepinephrine. 2. Huaora He kaha te whakahekenga o te Huaora C me te tino pai o te wai-wairewa antioxidant, ka taea te whakaiti i nga rauropi hydroxyl, superoxides me etahi atu waikura kaha i roto i te tinana o te tangata, ka taea te tango i nga rauropi kore utu me te aukati i te lipid peroxidation. 3. Whakanuia te mate Ko te mahi phagocytic o te leukocyte e pa ana ki te taumata huaora i roto i te plasma.Ko te painga antioxidant o te huaora C ka taea te whakaheke i te here disulfide (-S - S -) i roto i te antibody ki te sulfhydryl (-SH), ka whakatairanga i te whakahekenga o te cystine ki te cysteine, me te mutunga ka whakatairanga i te hanganga o nga antibodies. 4. Whakakore Ka taea e nga pota nui o te huaora C te mahi i runga i nga katote whakarewa taumaha penei i te Pb2+, Hg2+, Cd2+, tāoke huakita, benzene me etahi lysins tarukino.Ko te tikanga matua e whai ake nei: ka taea e te whakaheke kaha o te huaora C te tango i te glutathione oxidized mai i te tinana o te tangata, katahi ka hanga he matatini me nga katote whakarewa taumaha ka tukuna mai i te tinana;Na te mea ko te hāora kei te waahi C2 o te huaora C he kino te utu, ka taea hoki te whakakotahi te huaora C ake ki nga katote whakarewa, ka peia atu i te tinana ma te mimi;Ka whakanui te Huaora C i te ngohe o te whana (hydroxylation) kia pai ai te whakakore i nga paihana me nga raau taero. 5. Absorption me te pākia Ko te whakaurunga o te huaora C na roto i te kai kai i roto i te tinana o te tangata ko te nuinga o te kawe kaha i roto i te whekau iti o runga e te kaikawe, a, he iti te nui ka uru mai e te diffusion hāngū.I te iti o te kai o te huaora C, tata katoa ka taea te ngongo, a ka tae te kai ki te 500 mg/d, ka heke te tere o te whakauru ki te 75%.Ka tere te uru o te huaora C ki roto i te tohanga toto, ka uru ki nga momo kopa me nga whekau o te tinana. Ko te nuinga o te huaora C ka whakahiatohia i roto i te tinana o te tangata ki te waikawa oxalic, 2, 3-diketogulonic acid, ka honoa ranei ki te waikawa sulfuric ki te hanga waikawa ascorbate-2-sulfuric ka peia ki roto i te mimi;Ko etahi ka peia ki roto i te mimi.Ko te nui o te huaora C ka puta i roto i te mimi ka pa ki te kai huaora C, te mahi o te whatukuhu, me te nui o te mahara e rongoa ana i roto i te tinana. |
| Tikanga rokiroki | A ape i te penapena me nga waikura kaha me te kawakore, ka penapena ki roto i te ipu hiri kua whakakiia ki nga hau koretake i te pāmahana iti.
