Description

L-[6-13C]Sorbose is a stable isotope-labeled analog of L-sorbose, a key sugar intermediate, where the carbon-13 isotope is specifically incorporated at the 6-position. This compound is essential for advanced metabolic and biochemical research, providing a precise tracer for studying carbohydrate metabolism, enzymatic pathways, and flux analysis. It is primarily utilized by research institutions, pharmaceutical R&D departments, and diagnostic manufacturers engaged in isotope dilution mass spectrometry (IDMS), NMR spectroscopy, and the development of labeled internal standards.

Application

• Isotope-Labeled Internal Standard: Used in quantitative mass spectrometry (LC-MS/MS, GC-MS) for the accurate measurement of L-sorbose and related metabolites in complex biological matrices.
• Metabolic Pathway Tracing: Serves as a crucial tracer in 13C metabolic flux analysis (13C-MFA) to map and quantify pathways in microbial, plant, and mammalian systems.
• Biochemical Research: Employed in enzymatic studies to investigate the mechanisms of ketose metabolism and isomerase activities.
• Pharmaceutical Development: Used in the research and development of novel therapeutics and diagnostics where understanding sugar metabolism is critical.
• Nutritional Science Studies: Applied in research on sugar absorption, utilization, and the biochemical basis of dietary sugars.
