Description

D-[Ul-13C6]Galactose is a stable isotope-labeled analog of the monosaccharide galactose, uniformly labeled with carbon-13 at all six carbon positions. This high-purity labeled compound is essential for advanced metabolic research, providing a critical tracer for precise quantification and pathway analysis. It is primarily utilized by researchers and manufacturers in the pharmaceutical, biotechnology, and diagnostic sectors for applications including NMR spectroscopy, mass spectrometry-based metabolomics, and the development of labeled internal standards.

Application

• Metabolic Flux Analysis (MFA): Serves as a crucial tracer for studying galactose metabolism and interconnected pathways in cell cultures and biological systems.
• Quantitative Mass Spectrometry: Used as an internal standard for the accurate, isotope-dilution mass spectrometry (IDMS) quantification of endogenous galactose and related metabolites.
• Nuclear Magnetic Resonance (NMR) Spectroscopy: Provides a non-radioactive, highly sensitive probe for elucidating metabolic structures and dynamics in real-time.
• Drug Metabolism and Pharmacokinetics (DMPK): Enables the detailed tracking of drug metabolites and the study of carbohydrate-involved metabolic pathways.
• Clinical Diagnostics Development: Employed in the calibration and validation of assays for inborn errors of metabolism, such as galactosemia.
• Biochemical Research: Facilitates the study of enzyme mechanisms, glycosylation processes, and carbohydrate-protein interactions.
