In humans, ascorbic acid is an essential vitamin, anti-oxidant and co-factor of a variety of metal ion-dependent enzymatic reactions. In this review, the transport of L-ascorbic acid is described from food to target cells. Transport of ascorbic acid across the plasma membrane is facilitated by members of the SLC23 family, SLC23A1/SVCT1 and SLC23A2/SVCT2. We present in silico models of these tra…
