Sodium, potasiyumu, na calcium umunyu wa acide acorbike bita ascorbates kandi bikoreshwa mu kubika ibiryo.Gukora aside irike ya acorbike, irashobora gushirwa.Esters ya acide acide na acide, nka acide palmitike kugirango ibe palmitate ya ascorbyl na acide stearic kugirango ibe asorbike stearate, ikoreshwa nka antioxydants mubiribwa, imiti, no kwisiga.Acide ya Ascorbic nayo ni ngombwa muri metabolism ya acide amine.Ifasha kurinda selile kwangirika kwubusa, ifasha kwinjiza fer, kandi ni ngombwa mubikorwa byinshi byo guhinduranya.
