I-sodium, i-potassium, kunye ne-calcium iityuwa ze-ascorbic acid zibizwa ngokuba yi-ascorbates kwaye zisetyenziswa njengezigcini zokutya.Ukwenza i-ascorbic acid e-fat-soluble, inokuthi i-esterified.I-Esters ye-ascorbic acid kunye ne-acids, ezifana ne-palmitic acid ukwenza i-ascorbyl palmitate kunye ne-stearic acid ukwenza i-ascorbic stearate, isetyenziswa njenge-antioxidants ekutyeni, kumayeza, nakwizinto zokuthambisa.I-ascorbic acid nayo ibalulekile kwimetabolism yezinye ii-amino acids.Inceda ukukhusela iiseli kumonakalo omkhulu wamahhala, inceda ukufunxa intsimbi, kwaye iyimfuneko kwiinkqubo ezininzi ze-metabolic.
