Amylopectin is a branched chain polymer of glucose found in plants, while glycogen is a highly branched polymer of glucose found in animals and humans. Both serve as storage forms of glucose, with glycogen being the main form of energy storage in animals and humans, while amylopectin is the main form of energy storage in plants.

How is glycogen and amylopectin alike?

Both glycogen and amylopectin are polysaccharides composed of glucose units linked together by alpha glycosidic bonds. They are both storage forms of glucose in organisms, with glycogen being the main storage form in animals, and amylopectin being a key component of starch in plants.


Does glycogen and amylopectin have a helical structure like amylose and if yes why is it that glycogen and amylopectin form red-violet colouration with potassium iodide?

Yes, they are helical. The change in colouration is due to iodine being trapped in the helix. Difference in colour is due to the different wavelength of light being absorbed when iodine form bonds with the glucose molecules in the helix.


The structural difference between amylose and amylopectin?

Amylose is type of starch which is unbranched. Consisting 1-4 Alfa glycosidic linkage. It is not easy to digested and takes less space than amylopectin. Amylopectin is branched and consisting 1 alfa 1-6 linkage per 30 alfa 1-6 linkage. It is similar to glycogen expecting lower level of branching.


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.....


Are starches with a relatively large amount of amylose digested more quickly than those with amylopectin?

Enzymes are often substrate-specific, meaning they will only catalyze a reaction with a certain molecule. The difference in structure between amylose and amylopectin causes amylase to catalyze one and not the other.


What linkages would you expect to find at a branch point in glycogen or amylopectin?

At a branch point in glycogen or amylopectin, you would expect to find α-1,6 glycosidic linkages. These linkages connect the linear chains to the branch point, forming the characteristic tree-like structure of these polysaccharides. In contrast, the main linear chains are connected by α-1,4 glycosidic linkages.


What type of polysaccharide is found in potatoes?

Starch is found potatoes, not Glycogen. Glycogen is the plant equivalent of animal glycogen. A potato has starch but no glycogen; muscle cells have glycogen but no starch. The starch we eat is broken into glucose in the stomach/small intest and then reassembled in the muscle cells as glycogen.


What is the difference between liver glycogen and muscle glycogen?

Liver glycogen has low glycogenin content as compared to muscle glycogen.. liver glycogen responds to glucagon but muscle glycogen responds to catecholamines.. liver glycogen is used for the maintenance of blood glucose levels, but muscle glycogen is used for the supply of energy to the muscles liver glycogen can be completely broken down to glucose because of the presence of glucose 6 phosphatase, which does not occur in the muscles


What are the names of the two polymers formed from alpha gluscose?

The two polymers formed from alpha glucose are starch and glycogen. Starch is the storage form of glucose in plants, while glycogen is the storage form of glucose in animals.


The main structural difference between starch glycogen cellulose comes from?

The main structural difference comes from the difference in the sequence of bonds in glycogen and cellulose and starch where the three of them composed mainly of glucose and its derivatives Starch, glycogen and cellulose are all polymers of glucose. They differ in the type of glucose present and the bonds which link thr glucose monomers together. Starch and glycogen are made from alpha-glucose. This is an isomer of glucose in which the hydroxyl (-OH) group attached to carbon number 1 is below the plane of the ring. Starch is itself composed of two types of polymer:amylose and amylopectin. In amylose, the glucose monomers are linked by 1,4 glycosidic bonds. This means that the bond connects carbon atom number 1 in one glucose to carbon atom number 4 in the other glucose. This produces an unbranched chain of glucose which then folds up to form a coil or helix. In amylopectin there are two types of glycosidic bonds: 1,4 and 1,6. The 1,4 links are the same as in amylose. In addition some glucose molecules have a glycosidic link from carbon atom number 6 to carbon atom number 1 in a new glucose molecule. This produces a branch point in the amylopectin molecule. Amylopectin is therefore a branched polymer. Glycogen is similar in structure to amylopectin, but branches more frequently. Cellulose is an unbranched polymer composed of beta glucose molecules. Beta glucose is an isomer of glucose in which the hydroxyl group attached to carbon 1 is above the plane of the ring. The glucose monomers are linked by 1,4 glycosidic bonds. Hydrogen bonds between adjacent cellulose molecules allow them to form strong fibres, which suite them to their role as the main structural component of plant cell walls.

What is the difference between amylose and amylopectin in starch and how do they contribute to the overall structure and function of starch molecules?

Amylose and amylopectin are two types of polysaccharides found in starch. Amylose is a linear chain of glucose molecules, while amylopectin is a branched chain. Amylose contributes to the compactness and stability of starch molecules, while amylopectin provides branching points that allow for more interactions and flexibility. Together, they create a complex structure that can be easily broken down by enzymes for energy release in the body.


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%).
