Description

D-[1-13C]Tagatose is a stable isotope-labeled analog of the rare ketohexose sugar, D-tagatose, specifically enriched with carbon-13 at the C-1 position. This precise isotopic labeling makes it an indispensable tool for advanced metabolic and biochemical research, enabling accurate tracing and quantification in complex biological systems. It is primarily utilized by researchers and manufacturers in the pharmaceutical, nutraceutical, and analytical chemistry sectors for applications such as metabolic pathway studies, internal standards for mass spectrometry, and the development of diagnostic assays.

Application

• Metabolic Research & Tracer Studies: Used as a stable isotope tracer to investigate carbohydrate metabolism, glycolysis, and the tagatose pathway in microbial and mammalian systems.
• Mass Spectrometry Internal Standard: Serves as a critical internal standard for the accurate quantification of D-tagatose in complex biological matrices using GC-MS or LC-MS techniques.
• Pharmaceutical Development: Employed in the research and development of new therapeutic agents, particularly in studies related to diabetes, obesity, and metabolic disorders.
• Nutraceutical & Food Science Research: Used to study the behavior, absorption, and health effects of tagatose as a low-calorie sweetener in product formulations.
• Enzymology & Biochemical Assays: Acts as a substrate for studying enzyme kinetics and specificity of kinases, isomerases, and other carbohydrate-processing enzymes.
• Diagnostic Reagent Manufacturing: A key component in the production of calibrated reagents and kits for clinical diagnostics and research.
