Description

α-D-[1-13C]Galactopyranosyl 1-Phosphate Dipotassium Salt is a high-purity, isotopically labeled biochemical reagent essential for advanced metabolic and enzymatic research. This compound serves as a critical, stable-isotope labeled substrate for tracing galactose metabolism and studying the mechanisms of enzymes like galactose-1-phosphate uridylyltransferase. It is primarily required by pharmaceutical R&D laboratories, academic research institutions, and diagnostic developers focused on inborn errors of metabolism, such as Galactosemia, and carbohydrate pathway analysis.

Application

• Metabolic Pathway Tracing: Used as a 13C-labeled tracer in NMR and mass spectrometry studies to elucidate galactose metabolic fluxes and kinetics.
• Enzyme Kinetics & Inhibition Studies: Serves as a key substrate for assaying the activity and inhibition of galactose-1-phosphate uridylyltransferase (GALT) and related enzymes.
• Biomedical Research on Galactosemia: Critical for developing and validating diagnostic assays and researching therapeutic interventions for Galactosemia and related disorders.
• Glycobiology & Glycan Synthesis: Acts as a building block in the enzymatic synthesis of complex, isotopically labeled oligosaccharides and glycoconjugates.
• Stable Isotope-Labeled Standard (SILS): Employed as an internal standard in LC-MS/MS and GC-MS for the accurate quantification of galactose-1-phosphate in biological samples.
• Pharmaceutical Development: Used in drug discovery programs targeting carbohydrate-processing enzymes for metabolic diseases and cancer.
