No! Polypeptides are polymers of amino acids, joined by peptide bonds. They are the constituents of proteins. Starch, glycogen and cellulose are polysaccharides, which are polymers of simple sugars (monosaccharides) linked by glycosidic bonds. Polysaccharides are therefore carbohydrates.

∙ 8y agoYes starch is a polymer made up of many glucose molecules. The balanced equation to show this is n(C6 H12 06) ---> (C6 H10 05)n + nH20 In this equation n is a number which can have a value in the range of about 60 up to about 600. Made by plants from Glucose and used as a store for energy starch is a natural condensation polymer.

∙ 13y agoYes both are polymers of glucose but starch is arranged in a way called alpha and cellulose called beta :)

∙ 11y agoyes because it is made up of multiple monosaccharides

Is cellulose a steroid?
No, it is a poly-saccharide ... of glucose - so is glycogen. Both glycogen and cellulose are polymers of the monomer Glucose - the two different ways that the two are chemically bonded [both in a chain] together account for the difference. Steroids are but a group of the corticosteroids - hormones, all of them.
Which characteristic do glycogen and starch share?
They are both made up of chains of glucose molecules, with glycogen being the form for animals and starch being the form for plants.
How does glucose differ from sucrose and cellulose and starch?
Glucose is a monosaccharide (A single sugar 'unit'). It has 6 carbons and is an aldohexose.Sucrose is a dissaccharide. Meaning it is made up of two monosaccharide units. These units are a cyclic Glucose and a cyclic Fructose.Cellulose and Starch are both polysaccharides. Made up of many many individual sugar units or monomers. You can say they are sugar polymers.Starch is a glucose polymer. The two principal forms Amylose and Amylopectin are made up of alpha-D-Glucose monomers connected via alpha-1,4-glycosidic linkages.Cellulose is also a glucose polymer. But has alternating beta-D-Glucose monomers connected via a beta-1,4-glycosidic link.Important note regarding starch vs cellulose, is that most animal (including humans) have an enzyme to hydrolyze starch (or cleave the alpha-glycosidic linkages) but not enzyme for the beta-link in cellulose. Therefore we can not digest cellulose as a energy source.In short. Glucose: a monosaccharide. Sucrose: dissaccharide. Starch and Cellulose: Polysaccharides.
How are statch and glycogen related?
They are both polymers of glucose
Contrast the structure and function of starch with those of cellulose in plant cells?
Starch and Cellulose are both built on the same building block, Glucose, but are arranged differently. Because of this, they exhibit some different properties. Most importantly, the human body is capable of digesting starch, but not cellulose.
What do starch and cellulose have in common?
Both are glucose polymers.
What is the monomer present in cellulose?
Starch and cellulose are both polysaccharides therefore made up of mono-saccharides such as glucose. There is more information at the related link.
Starch and cellulose are polysaccharides but you can eat or digest starch and not the cellulose why?
Both starch and cellulose are polymers of glucose. However, the individual glucose units are linked differently in the two. Humans have an enzyme which is capable of breaking the linkages used to form starch, but do not have one that can break the linkage used to form cellulose. (If you want the technical terms, cellulose uses a beta(1-4) link and starch uses both alpha(1-4) and alpha(1-6) links.)
What do glycogen cellulose and starch all have in common?
Starch and cellulose are two common carbohydrates. Both are macromolecules with molecular weights in the hundreds of thousands. Both are polymers (hence "polysaccharides"); that is, each is built from repeating units, monomers, much as a chain is built from its links. The monomers of both starch and cellulose are the same: units of the sugar glucose. Starch contains alpha-glucose as monomer, whereas cellulose contains beta-glucose.
What does cellulose and starch have in common?
They are both polysaccharides composed of glucose monomers.
What polysaccharides are present in starch?
The polysaccharides Amylose and Amylopectin are present in starch, these are both polymers of glucose and they are interconvertible.
What substance makes starch?
Starch is made up of amylose and amylopectin. Both of these are polymers of glucose molecules.
What is the 2nd use of carbs in plants?
Plants make carbohydrates beginning with glucose. This is then chained together to make all the other types of carbohydrates: various simple sugars, complex starches, or fibrous cellulose & pectin. Sugar and starch are food reserves but cellulose and pectin are structural elements of the cell wall in a plant.The wall is made rigid by long fibrils of cellulose, a polymer of glucose, embedded in other polymers like pectin & lignin. Starch comes in two kinds but both are also glucose polymers..
Cellulose and starch are both polymers of glucose yet most mammals can use starch but not cellulose as a source of fuel?
mammals have very specific enzymes, one that breaks down starch and another that breaks down glycogen. however, the human digestive system does not have an enzyme to break down the polymer cellulose. cellulose is a straight-chain polysaccharide with glucose-glucose linkages different from those in starch or glycogen. some herbavores such as cattle, rabbits, termites, and giraffes have specially developped stomachs and intestines that hold enzyme-producing bacteria or protozoa to aid in the breakdown of cellulose. it is the different glucose-glucose linkages that make cellulose different from starch. recall that, when glucose forms a ring structure, the functional groups attached to the ring are fixed in a certain orientation above or below the ring. our enzymes are specific to the orientation of the functional groups, and cannot break down the glucose-glucose linkages found in cellulose.
Why are starch and cellulose considered different compounds even though they are built from the same monomer?
Starch and cellulose are both polymers built from glucose, but the glucose molecules are arranged differently in each case. Having different arrangements means that starch and cellulose are different compounds. They serve different functions in the plants that make them. Your body also uses starch very differently from the way it uses cellulose.
Starch is an example of?
They are all carbohydrates, meaning they are generated from carbon, hydrogen, and oxygen. Sugars are in the formation (CH2O)n, meaning they have "n" number of units of 1 carbon atom and 1 water "molecule." Glycogen, starch, and cellulose are all polysaccharides, which are sugars bonded together through condensation (water-leaving) reactions.
Is cellulose a steroid?
No, it is a poly-saccharide ... of glucose - so is glycogen. Both glycogen and cellulose are polymers of the monomer Glucose - the two different ways that the two are chemically bonded [both in a chain] together account for the difference. Steroids are but a group of the corticosteroids - hormones, all of them.
