What are the monomers found in starch?
glucose monomers
Starch is a polysaccharide comprising glucose monomers joined in α 1,4 linkages. The simplest form of starch is the linear polymer amylose; amylopectin is the branched form.
What are the monomers in cellulose?
Cellulose is made of glucose monomers in the beta form, and this results in a chain where every other monomer is flipped upside down relative to its neighbors. Image modified from OpenStax Biology. Unlike amylose, cellulose is made of glucose monomers in their β form, and this gives it very different properties.
What are starch and cellulose polymers of?
Cellulose and starch are identical polymers that have the same repeat units dependent on glucose, and are composed of the same glucose and monomer.
What is the monomer unit of starch glycogen and cellulose?
Starch: The monomer of starch is alpha glucose. Cellulose: The monomer of cellulose is beta glucose. Glycogen: The monomer of glycogen is alpha glucose.
Is cellulose a polymer or monomer?
glucose
Cellulose is a linear polysaccharide polymer with many glucose monosaccharide units. The acetal linkage is beta which makes it different from starch.
What makes cellulose different from starch?
The main difference between starch, cellulose and glycogen is that starch is the main storage carbohydrate source in plants whereas cellulose is the main structural component of the cell wall of plants and glycogen is the main storage carbohydrate energy source of fungi and animals. Starch is the polysaccharide synthesized by green plants as their main energy store.
What does cellulose and starch have in common?
Starch and Cellulose are macromolecules belonging to the same group of carbohydrates. Carbohydrates are one of the common forms of energy sources in food. They have the molecular formula CH2O. Several monomer units of glucose, interconnected through chemical linkages, make up these macromolecules. Thus, they have a high molecular weight.
What is true of both starch and cellulose?
Although both starch and cellulose are polymeric forms of glucose, they differ in their chemical and physical properties. These differences are mainly attributed to the difference in linkages. Cellulose has beta 1,4 linkages between glucose molecules whereas starch has 1,4 alpha linkages between glucose molecules.
Is starch a monomer or a polymer?
it is one unit, so a glucose molecule is a monomer. It can form a polymer starch or glycogen when a large number of glucose molecules (units) joined together by glycosidic bonds.
