D-(?)-Fructose

D-(-)-Fructose (CAS No.: 57-48-7) is a naturally occurring monosaccharide widely distributed in plants, including fruits and honey, and serves as a fundamental carbohydrate substrate in cellular metabolism and energy homeostasis. As an endogenous sugar, it participates in diverse biochemical processes, including glycolytic and fructolytic pathways, and has been shown to influence metabolic regulation through modulation of specific enzyme activities and signaling cascades associated with carbohydrate metabolism. In experimental systems, D-(?)-Fructose is frequently utilized as a model compound to investigate metabolic flux, insulin-independent glucose handling, and the regulation of key metabolic pathways, making it a valuable probe in studies of metabolic disorders and cellular energy balance. It also functions as a precursor in disaccharide formation, such as sucrose, reflecting its central role in carbohydrate biochemistry. In vitro studies typically employ concentrations spanning the millimolar range to assess its effects on enzymatic activity, cellular metabolism, and pathway regulation, although experimental conditions vary depending on the model system and research objectives. Its well-characterized biological relevance and compatibility with a wide range of biochemical and cell-based assays make D-(?)-Fructose a versatile reagent for mechanistic studies and compound screening in metabolic and biochemical research contexts.
