Abstract
I HAVE adduced evidence1 that manganese has a specific role in the synthesis of ascorbic acid by plants and animals. Until now the evidence of the synthesis of ascorbic acid in presence of manganese has been chemical; that is, by titration with the indophenol reagent. Evidence that the indophenol-reducing substance synthesized is identical with vitamin C has now been obtained.
