O le sodium, potassium, ma le calcium salts o acids ascorbic e taʻua o ascorbates ma e faʻaaogaina e fai ma meaʻai.Ina ia mafai ona solu ga'o ascorbic acid, e mafai ona esterified.Esters o le ascorbic acid ma acids, e pei o le palmitic acid e fausia ai le ascorbyl palmitate ma le stearic acid e fausia ai le ascorbic stearate, e faʻaaogaina e fai ma antioxidants i meaʻai, vailaʻau, ma mea teuteu.Ascorbic acid e taua foi i le metabolism o nisi amino acids.E fesoasoani e puipuia sela mai faʻaleagaina faʻamaʻi saoloto, fesoasoani i le faʻaogaina o le uʻamea, ma e manaʻomia mo le tele o gaioiga metabolic.
