I-Ascorbic Acid yaziwa nangokuthi i-Vitamin C
Isingeniso
I-Ascorbic Acid iyinhlanganisela ye-polyhydroxy ene-chemical formula C6H8O6. Isakhiwo sifana neglucose, futhi amaqembu amabili asondelene e-enol hydroxyl endaweni yesi-2 neyesi-3 ku-molecule ahlukaniswa kalula ukuze akhulule i-H+, ngakho-ke inohlobo lwe-asidi, eyaziwa nangokuthi i-L-ascorbic acid. I-Vitamin C inendawo yokunciphisa eqinile futhi i-oxidized kalula ku-dehydrovitamin C, kodwa ukusabela kuyabuyiselwa emuva, futhi i-ascorbic acid ne-dehydroascorbic acid inomsebenzi ofanayo wokuphila. Kodwa-ke, uma i-dehydroascorbic acid iphinde igaywe nge-hydrolyzed ukuze yakhe i-diketogulonic acid, ukusabela ngeke kushintshe futhi ukusebenza kahle komzimba kuzolahleka ngokuphelele.

Isicelo
1. Uvithamini C ungowokwakhiwa kwamasosha omzimba kanye ne-collagen, ukulungiswa kwezicubu (kuhlanganise nemiphumela ethile ye-redox), i-metabolism ye-phenylalanine, i-tyrosine, ne-folic acid, ukusetshenziswa kwensimbi nama-carbohydrate, ukuhlanganiswa kwamafutha namaprotheni, ukugcinwa kwamasosha omzimba, i-hydroxyl Antioxidant 5-hydroxytryptamine iyadingeka ukuze kugcinwe ubuqotho be-abshem nokukhuthaza ubuqotho begazi insimbi. Ngasikhathi sinye, i-vitamin C nayo ine-anti-oxidation, i-anti-free radicals, futhi ivimbela ukwakheka kwe-tyrosinase, ukuze kuzuzwe umphumela wokuba mhlophe nokukhanyisa amabala.
2. Emzimbeni womuntu, i-vitamin C iyi-antioxidant esebenza kahle kakhulu esetshenziselwa ukunciphisa ukucindezeleka kwe-oxidative ye-ascorbate peroxidase sch. Kunezinqubo eziningi ezibalulekile ze-biosynthetic ezidinga no-vitamin C ukuthi abambe iqhaza.
3. Njengoba izilwane eziningi ezincelisayo zingahlanganisa uvithamini C esibindini, ayikho inkinga yokuntuleka; Nokho, izilwane ezimbalwa ezinjengabantu, izinkawu, nezingulube zensimu azikwazi ukuhlanganisa uvithamini C ngokwazo futhi kufanele zimukelwe ngokudla nezidakamizwa.
