Usawoti we-sodium, i-potassium, ne-calcium we-ascorbic acid ubizwa ngokuthi ama-ascorbates futhi asetshenziswa njengezilondolozi zokudla.Ukwenza i-ascorbic acid encibilike ngamafutha, ingafakwa esterified.Ama-Esters e-ascorbic acid nama-acids, afana ne-palmitic acid ukuze akhe i-ascorbyl palmitate ne-stearic acid ukuze enze i-ascorbic stearate, asetshenziswa njengama-antioxidants ekudleni, kwezemithi, nasezintweni zokugcoba.I-Ascorbic acid nayo ibalulekile kumetabolism yamanye ama-amino acid.Isiza ukuvikela amangqamuzana ekulimaleni kwama-radical mahhala, isiza ukumuncwa kwensimbi, futhi ibalulekile ezinqubweni eziningi ze-metabolic.
