Used as a key metabolic intermediate in biochemical research, particularly in studies related to glucose and carbohydrate metabolism, as well as insulin signaling pathways. Trehalose 6-phosphate, in its dipotassium salt form, enables scientists to investigate its role in regulating sucrose levels, starch synthesis, and stress responses in plants, microbes, and some animal cells. Commonly applied in enzyme assays and cell culture experiments to modulate metabolic activity. Also utilized in the development and optimization of diagnostic kits targeting metabolic disorders. The potassium salt enhances solubility and stability in aqueous solutions, making it suitable for in vitro applications.
