The glucose produced by the plants is converted to the insoluble storage substances like starch and fats. Spirochete Overview & Examples | What is a Spirochete? Glucose residues are linked linearly by -1,4 glycosidic bonds, and approximately every ten residues a chain of glucose residues branches off via -1,6 glycosidic linkages. The downward arrow shows the dehydration synthesis reaction of glucose and fructose, producing sucrose and water. Create your account. Understand the difference between starch and glycogen in their function and use for plants and animals. Amylose is less abundant and linear, whereas amylopectin is more abundant and has a branched structure. The highly branched nature of glycogen means water has access to much more of the molecule than it does to amylopectin and as a result glycogen is more soluble. For some plants, it is their only means of producing and storing energy. Glycogen is more compact than starch, forming glycogen granules in It does the same thing as Starch, but it does that for animals. Starch can be used for commercial purposes while Glycogen cannot!
