Liver glycogen helps maintain blood glucose by storing glucose after meals and releasing it during fasting. Discover how glycogenesis, glycogenolysis, insulin, glucagon, glucose-6-phosphatase, and hepatic metabolism regulate liver glycogen.

Muscle glycogen provides skeletal muscle with a readily available source of carbohydrate energy during exercise and daily activity. Discover how glycogenesis, glycogenolysis, insulin signaling, GLUT4, nutrition, and exercise regulate muscle glycogen storage and utilization.

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.

Trehalose is a highly stable disaccharide with a unique α,α‑1,1 linkage. This article explains how its structure determines its exceptional chemical stability.
