Description

D-[5-13C]Galactose is a stable isotope-labeled analog of the monosaccharide galactose, specifically enriched with carbon-13 at the 5th position. This precise labeling makes it an indispensable tool for advanced metabolic research and diagnostic applications, enabling accurate tracing and quantification of galactose metabolic pathways. It is primarily utilized by research institutions, pharmaceutical developers, and diagnostic manufacturers in the fields of nuclear magnetic resonance (NMR) spectroscopy, mass spectrometry (MS), and in vivo metabolic flux analysis.

Application

• Metabolic Pathway Tracing: Used as a tracer in NMR and MS-based studies to elucidate the galactose metabolism pathway in cells and organisms.
• In Vivo Metabolic Flux Analysis (MFA): Critical for quantifying intracellular reaction rates in metabolic engineering and systems biology research.
• Clinical Research & Diagnostics: Serves as a substrate in advanced diagnostic assays and clinical research for disorders like galactosemia.
• Pharmaceutical Development: Employed in drug metabolism and pharmacokinetics (DMPK) studies for compounds targeting carbohydrate metabolism.
• Biochemical Reagent: Acts as a high-purity, labeled standard for enzymatic assays and biochemical reaction studies.
• Nutritional Science Research: Used to study galactose utilization and its role in human nutrition and physiology.
