For example, the activities of ascorbate-glutathione cycle enzymes, namely ascorbate peroxidase (APX, EC 1.11.1.11), monodehydroascorbate reductase (MDHAR, EC1.6.5.4), dehydroascorbate reductase (DHAR, EC 1.8.5.1), glutathione reductase (GR, EC 1.6.4.2). I want to try some new method and that is maybe faster.
