Used in biochemical research and diagnostic assays for the detection and quantification of glucose and related metabolites in metabolic pathways. Plays a key role in the pentose phosphate pathway studies, particularly in enzyme-coupled reactions where it generates NADPH, which is monitored spectrophotometrically. The lyophilized form ensures stability and ease of storage, making it suitable for use in clinical laboratories, pharmaceutical development, and enzymatic synthesis. Commonly employed in kits for glucose-6-phosphate dehydrogenase activity measurement and in metabolic flux analysis.
