Description

Xylose, D-, [1-14C] CAS NO 19588-10-4 is a carbon-14 labeled isotopologue of D-xylose, a fundamental pentose sugar. This radiolabeled compound is essential for precise metabolic and biochemical tracer studies, enabling researchers to track the fate of xylose molecules in complex biological systems. It is a critical tool for scientists in pharmaceutical development, carbohydrate metabolism research, and plant biochemistry who require high-specific-activity materials for sensitive detection and quantification.

Application

• Metabolic Pathway Tracing: Used as a radiotracer to study the uptake, distribution, and catabolism of D-xylose in microbial, plant, and mammalian systems.
• Pharmaceutical Research: Employed in ADME (Absorption, Distribution, Metabolism, and Excretion) studies for drug candidates that interact with carbohydrate pathways.
• Biochemical Assay Development: Serves as a labeled substrate for enzymatic assays, particularly for xylose isomerase, xylulokinase, and other pentose-metabolizing enzymes.
• Microbial Fermentation Studies: Tracks xylose utilization in engineered yeast and bacteria for biofuel (e.g., ethanol) and biochemical production.
• Plant Physiology Research: Investigates hemicellulose biosynthesis and degradation pathways in plant cell walls.
• Diagnostic Agent Research: Aids in the development of diagnostic tests, building on the principles of the D-xylose absorption test for gastrointestinal function.
