Used in biochemical and plant physiology research to quantify fructose kinase (FK) enzyme levels in plant tissues. Helps study sugar metabolism, energy regulation, and carbohydrate partitioning in plants. Commonly applied in studies related to photosynthesis, fruit ripening, and stress responses in crops and model plants. Enables researchers to assess FK activity under different environmental conditions or genetic modifications. Suitable for high-throughput screening in agricultural and plant biotechnology research.
