Glucose metabolism is a central component of human energy metabolism that controls how glucose is absorbed, transported, used, stored, and produced. It includes glycolysis, glycogen synthesis and breakdown, gluconeogenesis, the pentose phosphate pathway, and mitochondrial oxidation. These pathways are regulated by insulin, glucagon, nutrient availability, exercise, and energy status and are closely connected with insulin sensitivity, insulin resistance, metabolic syndrome, and diabetes.

Uridine diphosphate glucose (UDP-glucose) is an activated glucose donor that plays a central role in glycogenesis and carbohydrate metabolism. It is formed from glucose-1-phosphate and UTP and supplies glucose residues used by glycogenin and glycogen synthase during glycogen formation. UDP-glucose also participates in nucleotide-sugar metabolism, glycosylation, UDP-glucuronic acid production, and glucuronidation, linking glucose metabolism with several important cellular biosynthetic pathways.
