Heart Failure

Aldosterone is the primary mineralocorticoid. Aldosterone is a steroid hormone, and it is synthesized and secreted in response to renin-angiotensin system activation (RAS) or high dietary potassium by the zona glomerulosa (ZG) of the adrenal cortex. Aldosterone activity is dependent by the binding and activation of the cytoplasmic/nuclear mineralocorticoid receptor (MR) at cellular level.

D-Glucose 6-phosphate is a key central node metabolite in glucose metabolism. It serves as the initiating metabolite for glycolysis and the pentose phosphate pathway, as well as a substrate for glycogen synthesis.

D-Glucose 6-phosphate can be used in research related to non-insulin-dependent diabetes mellitus and heart failure.
