Dehydroascorbic acid reduction, enzymatic

Enzymatic dehydroascorbic acid reduction activity is also found in a number of tissues (Khatami et al, 1986 Rose and Bode, 1992). Stomach, brain, adrenals, small intestine, and lung have at least as much activity as the liver in guinea pigs. The kidney has long been known to serve in reabsorption of ascorbic acid renal... [Pg.390]

The reduction of dehydroascorbic acid by glutathione directly and in a non-enzymatic fashion has been suggested (Borsook et al., 1937). However, such stud-... [Pg.389]

FIGURE 12. The regeneration of ascorbic acid from dehydroascorbic acid by an enzymic and non-enzymatic mechanism. Dehydroascorbate reductase, using glutathione (GSH) as a cofactor, can regenerate ascorbic acid (ASA) from dehydroascorbic acid (DHAA) intracellularly. In an extracellular environment, DHAA reduction by GSH may occur nonenzymatically. Adapted from Bode et al. (1993). [Pg.390]
