D-Glucose 6-Phosphate- 13C6 disodium xhydrate is a 13C-labeled D-Glucose 6-phosphate disodium xhydrate. D-Glucose 6-phosphate disodium xhydrate is a key central node metabolite in sugar metabolism, serving as the initial metabolite of glycolysis and pentose phosphate pathway, and also a substrate for glycogen synthesis. D-Glucose 6-phosphate disodium xhydrate can act as a metabolic stress signal, especially when phosphoglucomutase (PGI) is inhibited, activating the mTOR pathway, promoting protein synthesis, and thereby participating in the remodeling process of the heart. D-Glucose 6-phosphate disodium xhydrate can be used in research related to non-insulin-dependent diabetes and heart failure.
