Ko te Huaora C (Huaora C), e mōhiotia ana ko te Waikawa Ascorbic (Waikawa Ascorbic), ko te tātai ngota ko C6H8O6, he pūhui polyhydroxyl kei roto e 6 ngā ngota waro, he huaora wairewa-wai e tika ana hei pupuri i te mahi ā-tinana noa o te tinana me te tauhohenga pākia rerekē o ngā pūtau. Ko te āhua o te Huaora C parakore he tioata mā, he paura tioata rānei, he ngāwari ki te wairewa i roto i te wai, he paku wairewa i roto i te etanoru, kāore e wairewa i roto i te etera, te benzene, te hinu, me ētahi atu. He waikawa, he whakaiti, he mahi whatu me ngā āhuatanga warowaihā te Huaora C, ā, he pānga hydroxylation, antioxidant, whakarei ake i te ārai mate me te tango paitini i roto i te tinana tangata. Ko te ahumahi te nuinga o te wā mā te tikanga biosynthesis (fermentation) hei whakarite i te Huaora C, ko te Huaora C te nuinga e whakamahia ana i roto i te mara hauora me te mara kai.
| Ngā āhuatanga ā-tinana me ngā āhuatanga matū | 1. Āhua: he karaihe mā, he paura karaihe rānei. 2. Wairewatanga: ngāwari te wairewa ki te wai, paku wairewa ki te etanoru, kāore e wairewa ki te etera, te benzene, te hinu, me ētahi atu. 3. Ngohe whatu: E 4 ngā isomer whatu o te Huaora C, ā, ko te hurihanga motuhake o tētahi otinga wai kei roto ko te waikawa L-ascorbic o te 0.10 g/ml he +20.5 °-+21.5 °. 4. Waikawa: Kei te Huaora C te turanga enediol, he waikawa, e whakaatuhia ana i te nuinga o te wā hei waikawa māmā ka taea te tauhohe ki te paikāpōnati konutai hei whakaputa tote konutai. 5. Ngā āhuatanga warowaihā: He rite te hanganga matū o te huaora C ki te huka, engari ko ngā āhuatanga o te huka, ka taea te whakawaikawa me te tango warowaihā hei whakaputa pentose i te aroaro, ā, ka ngaro tonu te wai hei whakaputa, mā te tāpiri i te pyrrole me te whakamahana ki te 50 ºC ka puta he kikorangi. 6. Ngā āhuatanga mimiti hihi-ā-rangi: Nā te noho mai o ngā hononga takirua honohono i roto i ngā ngota huaora C, ko te mimitinga mōrahi o tōna otinga waimeha he 243 nm te roanga ngaru, ā, ka whero te nekehanga o te roanga ngaru mimitinga mōrahi ki te 265 nm i raro i ngā āhuatanga waikawa, kawakore rānei. 7. Te Whakaiti: he tino taea te whakaiti i te rōpū enediol i roto i te huaora, he pumau i roto i te taiao waikawa, ā, he ngawari ki te whakangaro i roto i te wera, te mārama, te taiao aerobic me te taiao kawakore. Ka whakahāngaihia te Huaora C hei whakaputa i te hanganga diketo-based o te dehydrovitamin C, ka taea te whiwhi dehydrovitamin C i muri i te whakaiti hauwai o te huaora C. Hei tāpiri, i roto i te otinga kawakore me te otinga waikawa kaha, ka taea te whakahāngaihia anō te dehydrovitamin C hei whiwhi waikawa diketogulonic. |
| Te mahi ā-tinana | 1. Te Whakahāoraora Ka whai wāhi te Huaora C ki te tauhohenga hydroxylation i roto i te tinana tangata, e pā ana ki te pākia o ngā matū nui maha i roto i te tinana tangata. Hei tauira, ka taea e te Huaora C te whai wāhi me te whakatairanga i te hydroxylation o te cholesterol ki ngā waikawa au; Ka whakarei ake i te mahi whakauru o te oxidase; Ka whai wāhi ki te mahi hydroxylase me te whakatairanga i te hanganga o ngā neurotransmitters waikawa amino 5-hydroxytryptamine me te norepinephrine. 2. Ārai mate pāwera He kaha te whakaitiiti o te Huaora C, ā, he tino pai te antioxidant wairewa-wai, ka taea te whakaiti i ngā radical hydroxyl, ngā superoxide me ētahi atu waikura hohe i roto i te tinana tangata, ā, ka taea te tango i ngā radical kore utu me te aukati i te peroxidation lipid. 3. Whakarei ake i te ārai mate E pā ana te mahi whakapūpū o ngā leukocyte ki te taumata huaora i roto i te toto. Ka taea e te pānga ārai mate o te huaora C te whakaiti i te here disulfide (-S – S -) i roto i te paturopi ki te sulfhydryl (-SH), kātahi ka whakatairanga i te whakahekenga o te cystine ki te cysteine, ā, i te mutunga ka whakatairanga i te hanganga o ngā paturopi. 4. Whakakore i ngā paitini Ka taea e ngā horopeta nui o te huaora C te mahi ki ngā katote konganuku taumaha pērā i te Pb2+, Hg2+, Cd2+, ngā paitini kitakita, te benzene me ētahi lysin rongoā. Ko te tikanga matua koia tēnei: mā te kaha whakaiti o te huaora C ka taea te tango i te glutathione kua waikurahia mai i te tinana o te tangata, kātahi ka hanga he matatini me ngā katote konganuku taumaha hei tuku atu i te tinana; Nā te mea he utu kino te hāora i te tūranga C2 o te huaora C, ka taea hoki te whakakotahi i te huaora C me ngā katote konganuku ka tukuna atu i te tinana mā te mimi; Ka whakarei ake te Huaora C i te mahi whākōkī (hydroxylation) hei whakahaere i te tango paitini me ngā rongoā. 5. Te mimiti me te pākia o te tinana Ko te mimiti o te huaora C mā te kai e kainga ana e te tinana tangata ko te kawe kaha i roto i te whekau iti o runga e te kaikawe, ā, he iti noa te mimiti mā te horapa kore mahi. Ina iti te nui o te huaora C e kainga ana, tata katoa ka taea te mimiti, ā, ina tae te nui o te huaora C ki te 500 mg/rā, ka heke te tere mimiti ki te 75%. Ka tere te mimiti o te huaora C ki roto i te toto, ka uru ki ngā kiko me ngā okana rerekē o te tinana. Ko te nuinga o te huaora C ka hurihia i roto i te tinana tangata hei waikawa oxalic, 2, 3-diketogulonic acid, ka honoa rānei ki te waikawa whanariki hei hanga waikawa ascorbate-2-sulfuric ka tukuna ki roto i te mimi; ko ētahi ka tukuna ki roto i te mimi. Ko te nui o te huaora C ka tukuna ki roto i te mimi ka pāngia e te kai huaora C, te mahi a te whatukuhu, me te nui o te mahara e rongoatia ana e te tinana. |
| Tikanga rokiroki | Kaua e rongoatia me ngā waikura kaha me ngā kawakore, ā, rongoatia ki roto i tētahi ipu hiri kua whakakiia ki ngā hau kore mahi i ngā pāmahana iti.
