Acide ya Ascorbic ni polyhydroxy ivanze na formula ya chimique C6H8O6. Imiterere isa na glucose, kandi amatsinda abiri yegeranye ya enol hydroxyl kumwanya wa 2 nuwa 3 muri molekile yatandukanijwe byoroshye kugirango arekure H +, bityo ikaba ifite imiterere ya aside, izwi kandi nka L-ascorbic aside. Vitamine C ifite imitungo ikomeye igabanya kandi ihindurwamo okiside ya dehydrovitamine C, ariko reaction irahinduka, kandi aside asorbike na aside dehydroascorbic ifite imikorere imwe ya physiologiya. Ariko, niba aside ya dehydroascorbic irushijeho kuba hydrolyz kugirango ikore aside diketogulonic, reaction izaba idasubirwaho kandi imikorere ya physiologique izabura burundu.
