Vitamin C can be transported into the cell either as its reduced form or dehydroascorbate (oxidized form), using active sodium-dependent transporters (SVCT1 and SVCT2) and facilitative glucose transporters (GLUTs) (André et al., 2010). GLUTs also permit the permeation of vitamin C into mitochondria. Besides the protective role of vitamin C against oxidative injury within the cytosol, this water-soluble nutrient can also confer protection to mitochondria that are targets of oxidative attacks resulting from ROS produced as a side product of the respiratory chain that is active within mitochondria. Several beneficial functions have been attributed to vitamin C, . as.
