Description

D-[4-13C]Galactose is a stable isotope-labeled analog of the monosaccharide galactose, specifically enriched with carbon-13 at the 4-position. This high-purity labeled compound is essential for advanced metabolic research, enabling precise tracking and quantification of galactose pathways in biological systems. It is a critical reagent for scientists in pharmaceutical development, clinical diagnostics, and nutritional research who require accurate tracer studies and metabolic flux analysis.

Application

• Metabolic Flux Analysis (MFA): Used as a 13C tracer to map and quantify intracellular metabolic pathways in microbial, plant, and mammalian cell cultures.
• Drug Metabolism & Pharmacokinetics (DMPK): Serves as an internal standard in LC-MS and GC-MS for the accurate quantification of galactose and its metabolites in biological matrices.
• Clinical Research: Employed in studies of inborn errors of metabolism, such as Galactosemia, to investigate disorder mechanisms and potential therapeutic interventions.
• Nutritional Science: Facilitates research into galactose absorption, utilization, and its role in lactose metabolism and gut microbiome studies.
• Biomarker Discovery: Aids in the development of stable isotope dilution assays for potential diagnostic biomarkers related to carbohydrate metabolism disorders.
• NMR Spectroscopy: Provides a distinct 13C-NMR signal for structural elucidation and dynamic studies of glycans and glycoconjugates.
