What makes glycogen structurally different from cellulose




















Starch: The 1,4 glycosidic bonds in amylose and 1,4 and 1,6 glycosidic bond in amylopectin occur between monomers of starch. Cellulose: 1,4 glycosidic bonds occur between the monomers of cellulose. Glycogen: 1,4 and 1,6 glycosidic bonds occur between the monomers of glycogen. Starch: Amylose is an unbranched, coiled chain and amylopectin is a long branched chain, of which some are coiled.

Cellulose: Cellulose is a straight, long, unbranched chain, which forms H-bonds with adjacent chains. Glycogen: Glycogen is a short, many branched chains of which some chains are coiled. Starch: The molecular formula of starch is C 6 H 10 O 5 n. Cellulose: The molecular formula of cellulose is C 6 H 10 O 5 n. Glycogen: The molecular formula of glycogen is C 24 H 42 O Cellulose: Molar mass of cellulose is Glycogen: Molar mass of glycogen is Glycogen: Glycogen is found in animals and fungi.

Starch: Starch serves as a carbohydrate energy store. Cellulose: Cellulose is involved in the building of cellular structures like cell walls. Glycogen: Glycogen serves as a carbohydrate energy store. Glycogen: Glycogen occurs in small granules. Starch, cellulose, and glycogen are polysaccharides found in organisms.

Starch is found in plants as their major storage form of carbohydrates. Linear chains of starch are called amylose and when branched they are called amylopectin. Glycogen is similar to amylopectin but is highly branched. It is the major carbohydrate storage form in animals and fungi. Cellulose is a linear polysaccharide, which forms hydrogen bonds among several cellulose chains to form a fibrous structure.

It is the major component of the cell wall of plants, some algae, and fungi. Thus, the main difference between starch cellulose and glycogen is their role in each organism. Reference: 1. Berg, Jeremy M. Small granules. Cellulose is solely found in the plant only and is absent in vertebrates. In plants, it acts as the structural component and is present in the cell wall, especially in trunks, the woody area of the plants. Cellulose is the polysaccharide and is made up of numerous glucose units linking together forming the long chain.

The chain is unbranched, linear containing 10, to 15, D-glucose units. The above statement is important to notice as this is the only reason that human cannot digest hydrolyze cellulose, as the enzyme which is needed to the break the beta-glycosidic linkage is absent in humans. Though certain ruminating animals have the microorganisms in their gut, which can break the beta-glycosidic bonds.

Another type of polysaccharide, acting as the chief carbohydrate reserve for the plants, and the principal dietary source for the animals and humans. Starch occurs in two types of polymer amylose and amylopectin. Both the polymers are composed of the D-glucose, with the alpha glycosidic bonds known as glucan or glucosan.

Being of the same the glycosidic bond, amylose and amylopectin differ in their properties. Amylose is insoluble in water. Amylopectin has high molecular weight and is soluble in water. Starch is mainly found in cereals, vegetables, roots, tubers, etc. Glycogen, often termed as animal starch, though found in plants that do not contain chlorophyll like yeast, fungi, etc. It is also the homopolysaccharide having the glycogen bonds or linkages similar to that of the amylopectin, with the more branches.

Glycogen has short but highly branched chains with high molecular weight. It is abundantly present in liver, and also found in the brain, skeletal muscles, etc. Participation of carbohydrate is seen everywhere and in various forms. Polysaccharides are the most abundantly available in nature among carbohydrates and perform a variety of functions, such as energy storage or as components of plant cell walls.

Polysaccharides are very large polymers made up of tens to thousands of monosaccharides, linked by glycosidic linkages. Ccommon polysaccharides: Starch, glycogen, and cellulose. Heteropolymers can include, in addition to monosaccharides, sugars, amino sugars, or non carbohydrate substances. Heteropolymers are common in nature and are non reducing carbohydrates with no sweet taste.

Starch is a glucose polymer in which all repeat units are directed in one direction and connected by alpha bonds.

Starch is edible and can be eaten safely by humans as we have the enzymes which can break it down into glucose. It is a grain, with the main source for starch being potatoes, wheat, corn, and rice. These carbohydrates are broken down into glucose and used as a source of energy and a metabolism aid when reaching our bodies. Starch is less crystalline and is weaker than cellulose.

Despite the fact that raw starch is not soluble in cold water, it can be dissolved in warm water and can be used in different ways. It's most commonly used as food but has other uses as well. It can be used as a glue, for tightening up clothes and weaving linen, for thickening sauces and for paper treatment. Cellulose is a glucose polymer whose units can be rotated around the axis of a backbone of glucose unit polymer chains, and are connected by beta links.

It is the most natural organic compound and is a fundamental component of plant cells.
