Description

D-Galactose-3-13C is a stable isotope-labeled analog of the monosaccharide galactose, specifically enriched with carbon-13 at the third carbon position. This high-purity labeled compound is essential for advanced research requiring precise metabolic pathway tracing and quantification. It is primarily utilized by scientists and manufacturers in the pharmaceutical, biotechnology, and life science sectors for applications in metabolic flux analysis, drug development, and diagnostic research.

Application

• Metabolic Flux Analysis (MFA): Used as a tracer to study carbohydrate metabolism and glycolytic pathways in cell cultures and biological systems.
• Drug Metabolism & Pharmacokinetics (DMPK): Serves as an internal standard in mass spectrometry for the accurate quantification of galactose and related metabolites in preclinical studies.
• Biomedical Research: Enables detailed investigation into metabolic disorders such as galactosemia and other inborn errors of metabolism.
• Nutrient Utilization Studies: Applied in research to track the assimilation and conversion of galactose in microbial, plant, and animal models.
• Diagnostic Assay Development: Acts as a critical component in calibrating and validating clinical diagnostic kits and LC-MS/MS methods.
• Stable Isotope Labeling: Used in the synthesis of more complex 13C-labeled glycans, glycoproteins, or other biochemical probes for structural and functional studies.
