Blood glucose metabolic pathway

The blood glucose metabolic pathway consists of multiple interconnected enzymatic and regulatory steps that collectively control the concentration of glucose in the blood. This system integrates signals from hormones (primarily insulin and glucagon), nutrient status, and energy demand to regulate glucose uptake (via transporters like GLUT and SGLT), glycolysis (breakdown of glucose), gluconeogenesis (de novo synthesis), glycogenolysis (breakdown of glycogen), and glycogenesis (storage as glycogen). Dysfunction in these pathways can lead to metabolic diseases such as diabetes and hypoglycemia. The pathway includes numerous molecular targets (enzymes, receptors, and transporters) that can be selectively targeted for therapeutic intervention, but the pathway itself is a conceptual framework rather than a discrete molecular entity. It is not a single molecule, receptor, or protein but rather a composite of many biochemical routes and regulatory elements. For drug or therapeutic targeting, specificity to a particular molecule within this pathway (such as "insulin receptor" or "SGLT2 transporter") is necessary.
