Description

D-[11-13C]Talose is a stable isotope-labeled analog of the rare sugar D-talose, specifically enriched with carbon-13 at the C-11 to C-13 positions. This compound is a critical tool for advanced metabolic and biochemical research, enabling precise tracing and quantification of carbohydrate pathways. It is primarily utilized by research institutions and pharmaceutical companies engaged in isotope dilution mass spectrometry (IDMS), metabolic flux analysis, and the development of novel diagnostic agents.

Application

• Metabolic Pathway Tracing: As a 13C-labeled tracer for studying the metabolism of rare sugars and related glycan biosynthesis in biological systems.
• Isotope Dilution Mass Spectrometry (IDMS): Serves as an internal standard for the accurate quantification of D-talose and its derivatives in complex matrices.
• Pharmaceutical Research: Used in the development and validation of assays for drug metabolism and pharmacokinetic (DMPK) studies involving carbohydrate-based therapeutics.
• Glycobiology Studies: Aids in the investigation of enzyme mechanisms, carbohydrate-protein interactions, and the structure-function relationships of glycoconjugates.
• Nutritional Science Research: Employed to trace the fate and utilization of specific sugar isomers in nutritional studies and gut microbiome research.
• Diagnostic Agent Development: Potential use as a labeled precursor in the synthesis of contrast agents or probes for medical imaging techniques like PET (Positron Emission Tomography).
