L-galactono-1,4-lactone + ferricytochrome c Solanum tuberosum final enzyme in synthesis of ascorbic acid. L-Galactono-gamma-lactone dehydrogenase and vitamin C content in fresh-cut potatoes stored under controlled atmospheres: fresh-cutting provoces an increase in enzyme activity in potato strips in all atmospheres tested. Highest induction, 15.5fold, is observed in strips stored in air L-ascorbate + ferrocytochrome c
