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.

What else can I help you with?
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 are the examples of glucosans?
Examples of glucans include cellulose, starch, and glycogen. These are polysaccharides made of glucose units linked together in different ways, providing structural support (cellulose), energy storage (starch and glycogen), or a combination of both.
Which characteristic do glycogen and starch share?
Both glycogen and starch are polysaccharides, which are complex carbohydrates composed of multiple sugar units. Additionally, both glycogen and starch serve as storage forms of glucose in living organisms, with glycogen being stored in animals and starch in 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.
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.
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 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..
Glycogen is most similar to?
Starch in plants. Both glycogen in animals and starch in plants are polysaccharides that serve as storage forms of glucose. They are both branched polymers of glucose that can be broken down into glucose units when needed for energy.
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 and cellulose are polysaccharides but you can eat or digest starch and not the cellulose why?
Oh, dude, like, starch and cellulose are both polysaccharides, but our digestive enzymes can break down starch into glucose, which we can totally use for energy. Cellulose, on the other hand, is like the tough guy of the group - our enzymes can't really break it down, so it just passes through our system like, "See ya later, alligator!" So, yeah, that's why we can chow down on some fries but not on a salad made of pure cellulose.
What chemical elements are combined to make molecules of starch and cellulose?
Starch and cellulose are both composed of glucose molecules. Starch is made up of glucose molecules arranged in linear chains, while cellulose is made up of glucose molecules arranged in a linear structure with alternating bonds.
How are cellulose and starch similar?
Cellulose and starch are both polysaccharides made up of glucose molecules, but they differ in their structure and function. Cellulose is a structural component in plant cell walls, providing rigidity and support, while starch is a storage form of glucose in plants, serving as an energy reserve. Both are important carbohydrates in the diet and provide benefits to human health.
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.
What substance makes starch?
Starch is made up of amylose and amylopectin. Both of these are polymers of glucose molecules.
