Both glycogen and starch are polymers of glucose. Alpha 1,4 linkage of glucose produces chain linkage and Alpha1,6 linkage produces branching of chains. Glycogen has more brached chains than starch. More the number of branches means there are more terminal glucose molecules with alpha 1,4 linkage. More the number of terminal glucose linked with alpha1,4 linkages, more enzymes will be get a chance to hydrolyze the linkage.

Why does hydrolysis of starch take longer than hydrolysis of sucrose?
Hydrolysis is the separation of bonds, especially carbohydrates, through the use of water. It takes longer to separate starch than sucrose because of the larger number of carbons that need to be processed.
What is the animal starch properly called?
Glycogen is the storage form of glucose in animals and humans which is analogous to the starch in plants. Glycogen is synthesized and stored mainly in the liver and the muscles. Structurally, glycogen is very similar to amylopectin with alpha acetal linkages, however, it has even more branching and more glucose units are present than in amylopectin.Starch can be separated into two fractions--amylose and amylopectin. Natural starches are mixtures of amylose (10-20%) and amylopectin (80-90%).
Why are polymer forms of starch and glycogen utilized as storage forms of glucose by living cells rather than an equivalent amount of free glucose?
Glucose is osmotically actice since it is soluble. This increases the water content inside the cell, the cell eventually burst. Since glycogen and starch are insoluble it is better to convert glucose to starch (in plants) or glycogen (in animals).
How are starch and glycogen similar and how do they differ?
Startch have two types of polymer chain,one is amylose and another is amylopectin.Amylose is simple straight chain of glucose(1--->4 linkage),while amylopectin have branching.At branching point,there is 1--->6 linage and 1--->4 linkage in every subchain. So,in startch 1-6 linkage comes after 20 to 25 gucose monomer,while in gycogen this linkage comes very frequently.....
Why acetyl chloride hydrolyzed faster than benzoyl chloride?
The benzyl group acts as a protector retarding hydrolysis?
Does glucose release energy quicker than starch?
GLucose does release energy quicker than starch. this is because starches (CH2O) are the compounds in which glucose is stored.
Why is sugar recommended for a hypo as opposed to starch?
1) Sugar converts to glucose much faster than starch 2) Sugar is digested quicker than starch 3) Sugar raises blood sugar level in the body quicker
What is polysaccharide?
Polysaccharide are large numbers of carbohydrates found in or made by living organisms and microbes. They are large, complex molecules of hundreds to thousands of glucose molecules bonded together in ong long chainlike molecule. Polysaccharide is a polymeric carbohydrate structure. Is is structures that repeat units.
Why do animals use both glycogen and fat as energy stores while plants only use starch?
http://www.biology-online.org/biology-forum/about9759.html?p=74250&hilit=Sunflowerplants produce starch for use as energy storage polymer but plants also produce fats (another source of energy). Monounsaturated fats can also be found in nuts and olive oils, while polyunsaturated fats in sunflower and corn... Animals (or humans) would store energy as fats (aside from glycogen) since fats are less bulky than starch and are therefore suitable for mobile animals... would you rather see yourself gaining additional pounds when in stead of fat, youd store starch (of about the same energetically equivalent amount of fat)?Basically starch and glycogen has similar function: They are main forms of carbohydrate storage for plants and animals, respectively. They differ mainly in their structure-- that is glycogen being more extensively branched... Plants (however) produce starch and later on can undergo drying process (particularly in seeds).. Animals cannot store energy that is equivalent to plants storing 'dry starch'... since in animals, glycogen storage is associated with a concomitant storage of water..
Does oxidation of glucose yield more energy than glycogen?
No. The oxidation of glycogen yields more energy than glucose. You need to put energy in formation of the glycogen from glucose. Naturally, this energy is released, when you get get glucose from glycogen.
What is The main function of glycogen is?
A carbohydrate storage molecule in animals that can be accessed faster than fat molecules.Glycogen is a multibranched polysaccharide that serves as a form of energy storage in animals and fungi.
What stores glycogen in a cell?
If your body does not have any use for the glucose, it is converted into glycogen and stored it in the liver and muscles as an energy reserve. Your body can store about a half a day's supply of glycogen. If your body has more glucose than it can use as energy, or convert to glycogen for storage, the excess is converted to fat.
