Abstract
The content and redox-state of ascorbic acid in isolated vacuoles, plastids and mitochondria of red beetroot cells (Beta vulgaris L.) is established. The pool of oxidized ascorbic acid in vacuoles is higher than in other investigated organelles. At least three enzymes of vacuolar localization oxidize ascorbic acid and change its redox-state, such as phenolic peroxidase (EC 1.11.1.7), ascorbate peroxidase (EC 1.11.1.11) and, possibly, ascorbate oxidase (EC 1.10.3.3).
