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.....
What is the macromolecule for glycosidic?
Macromolecules are carbohydrates, proteins, lipids and nucleic acids. Glycosidic linkage is a crucial bond that make simple sugars to complex carbohydrates. This linkage can be cleaved by enzymes such as amylases when there is a need of energy (starch or glycogen to glucose).
Why cellobiose not formed from partial hydrolysis of glycogen and starch?
Cellobiose is not formed from the partial hydrolysis of glycogen and starch because they are composed of α-1,4-glycosidic linkages between glucose units, which can be easily hydrolyzed by enzymes like amylase. In contrast, cellobiose is composed of β-1,4-glycosidic linkages, which are not easily hydrolyzed by the enzymes that break down glycogen and starch. This difference in linkage orientation prevents cellobiose from being formed during the partial hydrolysis of glycogen and starch.
What is a glucosidic bond?
A glucosidic bond is a covalent bond that connects two sugar molecules via a condensation reaction, resulting in the formation of a glycosidic linkage. It is commonly found in carbohydrates like disaccharides (e.g., sucrose) and polysaccharides (e.g., starch).
What are the carbohydrate that are similar in structure to cellulose?
Cellulose is a biopolymer that is built by beta 1, 6 linkage between the glucose residues. The molecule that resembles it most closely is chitin that has N acetylglucosamine, that is the glucose aminocylated at 2' carbon. In hemicellulose, there is a backbone of glucose and there are side chains of some other glucose residues. Starch and glycogen are also made up of the glucose residues but they are linked by alpha 1-4 linkage.
Why does hydrolysis of glycogen is faster than the starch?
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.
Does cotton contain starches?
All plants and animals contain starch of some kind. Cotton fibers are cellulose which is a particular type of starch. Actually, that is not technically correct. A starch by definition has alpha 1,4 linkage between its molecules while cellulose has beta 1,4 linkage. If you used the iodine test for starch on a piece of cotton, you will get a negative result.
Why is starch a nonreducing sugar?
Reducing property of carbohydrate is lost due to alfa 1.4 linkage

STarch is held together by peptide bonds not glycosidic linkage?
This statement is incorrect. Starch is a polysaccharide composed of glucose units linked together by glycosidic bonds, not peptide bonds. Peptide bonds are formed between amino acids in proteins, not in carbohydrates like starch.
What is the bond joining monomers of starch?
The bond joining monomers of starch is a glycosidic bond. It forms between the hydroxyl group of one glucose molecule and the anomeric carbon atom of another glucose molecule, resulting in a covalent linkage between the monomers.
What type of bond linkage in starch and glycogen?
Starch and glycogen are both polysaccharides made up of glucose subunits linked together by alpha glycosidic bonds. These bonds form between the carbon 1 of one glucose molecule and carbon 4 of the next glucose molecule.
What is the macromolecule for glycosidic?
Macromolecules are carbohydrates, proteins, lipids and nucleic acids. Glycosidic linkage is a crucial bond that make simple sugars to complex carbohydrates. This linkage can be cleaved by enzymes such as amylases when there is a need of energy (starch or glycogen to glucose).

Is starch C6H10O5 ionic or covalent?
Starch is a complex carbohydrate composed of glucose units linked together through covalent bonds. The chemical formula for starch is typically represented as (C6H10O5)n, where n represents a large number of repeating units. The bonds between the carbon, hydrogen, and oxygen atoms in starch are covalent bonds, as they involve the sharing of electrons between atoms. Therefore, starch is a covalent compound.
Why cellobiose not formed from partial hydrolysis of glycogen and starch?
Cellobiose is not formed from the partial hydrolysis of glycogen and starch because they are composed of α-1,4-glycosidic linkages between glucose units, which can be easily hydrolyzed by enzymes like amylase. In contrast, cellobiose is composed of β-1,4-glycosidic linkages, which are not easily hydrolyzed by the enzymes that break down glycogen and starch. This difference in linkage orientation prevents cellobiose from being formed during the partial hydrolysis of glycogen and starch.
