How does the structure of amylose compare to the structure of glycogen?

∙ 13y ago
Recent research has actually shown that Glycogen IS actually a form of amylopectin. Amylopectin is a branched polysaccharide joined by alpha-1,4 linkages with branch points of alpha-1,6. The 1-4 linkage is because C1 of one glucose molecule is linked to the C4 of the next. The 1-6 linkage occurs every 10 glucose molecules or so. The alpha-amylase hydrolyzes only the alpha-1,4... NOT the alpha-1,6.

Why is amylopectin more compact than amylose?
Actually, amylose is more compact than amylopectin due to its helical structure. Amylose is unbranching and forms a compact helix, whereas amylopectin is a branching structure.
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.
Compare the two storage polysaccharides?
Glycogen is found in animals and Starches are found in plants.
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.
What is the Amylose content of rice?
starch is made up of two components - * amylose *amylopectine that corresponds with quality of rice...
What is the function of amylose?
Amylose helps keep the structure of plants amylose is good for storage in plants.
Why glycogen gives red colour with iodine?
When Iodine is added to amylose, the helical shape of the unbranched polysaccharide traps Iodine molecules, producing a deep blue-black complex. Amylopectin, cellulose, and Glycogen react with iodine to give red to brown colors. Glycogen produces a reddish-purple color.
Which of these carbohydrates is impossible for humans to digest cellulose amylose glycogen galactose?
cellulose

Two polysaccharides that store glucose are?
If by 2 polysaccharides you mean any two, then some of the common examples would be cellulose, peptidoglycan, starch (amylose and amylopectin), hemicellulose, chitin, glycogen ........... the list is almost endless.
What is the subtrate and subunit product of amylase?
The Substrate for amylase are starch (amylose and Amylopectin), glycogen, and various Oligosaccharides and the subunit is maltose.
What is an example of glycogen?
Glycogen is what animals use for short term energy production. So if you are looking at finding food with glycogen either to eat or stay away from it would be protein since this is where animals store their glycogen. When you eat glycogen it must be broken down into glucose and reconstructed in the body and stored as glycogen again.
What are the reactants of amylase?
The Substrate for amylase are starch (amylose and Amylopectin), glycogen, and various Oligosaccharides.
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.
Compare the two storage polysaccharides?
Glycogen is found in animals and Starches are found in plants.
What do potatoes store carbohydrates as?
Potatoes store carbohydrates as amylose (starch)Amylose is a linear polymer made up of D-glucose units.This polysaccharide is one of the two components of starch, making up approximately 20-30% of the structure. The other component is amylopectin, which makes up 70-80% of the structure.[1]Because of its tightly packed structure, amylose is more resistant to digestion than other starch molecules and is therefore an important form of resistant starch, which has been found to be an effective prebiotic.[2]
