Description

D-Arabinose-5-13C is a stable isotope-labeled analog of the naturally occurring pentose sugar, D-Arabinose, where the carbon atom at the 5-position is enriched with the 13C isotope. This compound is a critical tool in advanced research and development, enabling precise metabolic pathway tracing and quantitative analysis in complex biological systems. It is primarily utilized by scientists and manufacturers in the pharmaceutical, biotechnology, and life science sectors for applications in nuclear magnetic resonance (NMR) spectroscopy, mass spectrometry, and metabolic flux analysis.

Application

• Isotopic Tracer in Metabolic Studies: Used to elucidate and quantify metabolic pathways in microbial, plant, and mammalian cell cultures.
• Internal Standard for Mass Spectrometry (MS): Serves as a quantitative reference standard in LC-MS and GC-MS analysis for accurate measurement of arabinose and related metabolites.
• NMR Spectroscopy Probe: Enables detailed structural and dynamic studies of carbohydrate metabolism and enzyme mechanisms due to the distinct 13C signal.
• Pharmaceutical Research & Development: Critical for drug metabolism and pharmacokinetics (DMPK) studies to track the fate of sugar-based drug candidates.
• Biochemical Research: Used in enzymatic assays and studies of carbohydrate-active enzymes (CAZymes) like isomerases and kinases.
• Nutritional Science Research: Applied in studies investigating the metabolism of rare sugars and their potential health effects.
