Description

D-[1,2-13C2]Galactose is a stable isotope-labeled analog of the monosaccharide galactose, specifically enriched with carbon-13 at the 1 and 2 positions. This precise labeling makes it an indispensable tool for advanced metabolic research and diagnostic applications, providing critical insights into biochemical pathways. It is primarily utilized by research institutions, pharmaceutical developers, and clinical diagnostic laboratories engaged in tracer studies, metabolic flux analysis, and the development of stable isotope dilution mass spectrometry (SID-MS) assays.

Application

• Metabolic Tracer Studies: Used to trace and quantify the metabolic flux through pathways like the Leloir pathway, providing data for systems biology and metabolic engineering.
• Clinical Diagnostics & Biomarker Research: Serves as an internal standard in mass spectrometry for the accurate quantification of galactose and related metabolites in biological fluids, aiding in the diagnosis of disorders like galactosemia.
• Pharmaceutical R&D: Employed in drug metabolism and pharmacokinetics (DMPK) studies to investigate the catabolism and disposition of carbohydrate-based therapeutics.
• Nutritional Science Research: Facilitates the study of galactose absorption, utilization, and its role in human nutrition and gut microbiota metabolism.
• NMR Spectroscopy: Acts as a labeled substrate for nuclear magnetic resonance (NMR) studies to elucidate enzymatic mechanisms and structural dynamics.
