D-Fructose-6-phosphate (sodium salt)

D-Fructose-6-phosphate (sodium salt) is an endogenous metabolite and an intermediate in glycolysis and the pentose phosphate pathway^{[1, 2]}. D-Fructose-6-phosphate is produced from glucose-6-phosphate by the enzyme phosphoglucose isomerase and can be further converted to fructose-1,6-bisphosphate by fructose-1,6-bisphosphate kinase, thus driving glycolysis forward^[3]. The key role of D-Fructose-6-phosphate lies in its function as a central hub in energy metabolism and biosynthetic pathways; it is commonly used in studies of cellular metabolism, enzyme kinetics, and in vitro reconstitution of metabolic pathways^{[4, 5]}.

D-Fructose-6-phosphate (sodium salt)是一种内源性代谢物，是糖酵解和磷酸戊糖途径的中间产物^{[1, 2]}。D-Fructose-6-phosphate由葡萄糖-6-磷酸通过磷酸葡萄糖异构酶催化转化而来，并可在磷酸果糖激酶-1的催化下进一步转化为果糖-1,6-二磷酸，从而推动糖酵解的进行^[3]。D-Fructose-6-phosphate的核心作用在于作为能量代谢和生物合成代谢的枢纽，常用于细胞代谢研究、酶动力学分析以及体外重建代谢通路的实验体系中^{[4, 5]}。
