Glycogen and Starch: So Similar, yet so Different. Both carbohydrates are central to the primary metabolism of a large part of the living kingdom. Generally, animals, fungi, bacteria store glycogen, while plants largely rely on starch. This volume provides a broad and current views on both glycogen and starch, in lower and higher organisms. Beside biochemistry, physiology and regulation of glycogen and starch metabolism the reader can expect an insight into glycogen storage diseases and select methods and relevant techniques. While significant progress has been made in both fields, this volume emphasizes an opportunity of collaboration for researchers working on a major intersection of the living world.
