Application

Trehalose 6-phosphate (T6P) dipotassium salt has been used as a standard to measure T6P concentrations in potato tubers. It has also been used as a calibration standard in liquid chromatography-mass spectrometry (LC-MS) assay for measurement of T6P in plants.

Biochem/physiol Actions

Trehalose 6-phosphate (T6P) is synthesised from glucose-6-phosphate (G6P) and uridine 5-diphospho-glucose. Trehalose-6-phosphate synthase catalyzes this reaction. T6P serves as a precursor for the synthesis of trehalose. It regulates sugar metabolism in in Arabidopsis plants and promotes its growth. In plants, T6P blocks the action of sucrose nonfermenting-1-related protein kinase 1, which affects the energy and carbon metabolism.

Packaging
