Difference between Cellulose and Starch

If you are like most people, you probably think that cellulose and starch are the same things. After all, they both come from plants, right? Well, not exactly. While both of these substances play an important role in plant life, they are actually quite different from each other. In this blog post, we will take a closer look at the difference between cellulose and starch. We will also discuss what each of these substances does for plants. So, let’s get started!

Starch

Starch are polysaccharides consisting of a large number of glucose units joined together by glycosidic bonds. They are produced by all green plants, most notably by cereal grains, and are a major component of the human diet.

Cellulose

Cellulose is a polymer made up of multiple glucose units. It is an important structural component of the cell wall in plants and bacteria. Humans cannot digest cellulose.

Difference between cellulose and starch

Following are the factors on which cellulose and starch can be differentiated:

• Definition
• Background
• Glucose range
• Component
• Function
• Bonding role
• Type of chain
• Solubility in water
• Forms
• Glucose unit linkages
• Molar mass
• Availability

Now, let’s discuss the difference between bacteria and viruses on the basis of these factors individually.

On the basis of definition

Starch is a type of carbohydrate that is composed of glucose units. Cellulose, on the other hand, is a structural component that is found in the cell walls of plants. It is also made up of glucose units.

The difference between the two lies in their structure. Starch is a long, branched molecule while cellulose is a straight chain.

On the basis of background

Starch is found in all green plants. Cellulose, on the other hand, is found in the cell walls of plants and bacteria.

On the basis of glucose range

Starch has a lower glucose range as compared to cellulose.

On the basis of Component

Starch is a type of carbohydrate while cellulose is a type of fibre. the components of starch include amylose and amylopectin while the component of cellulose is beta-glucan.

On the basis of function

Starch is the chief storage carbohydrate in plants and it serves as an energy reserve. Cellulose, on the other hand, is a structural component that provides support and strength to plants.

On the basis of bonding role

Cellulose is responsible for providing strength and rigidity to the cell walls of plants. Starch, on the other hand, is a storage molecule that is responsible for storing energy in plants.

On the basis of type of chain

Starch is a long, branched molecule. Cellulose is a straight chain.

On the basis of solubility in water

Cellulose is soluble in water while starch is not.

On the basis of forms

Cellulose can exist in two forms – crystalline and amorphous. Starch, on the other hand, can exist in three forms – amylose, amylopectin and cyclodextrin.

On the basis of glucose unit linkages

Cellulose has beta glucose unit linkages while starch has alpha glucose unit linkages.

On the basis of molar mass

Cellulose has a higher molar mass than starch.

On the basis of availability

Starch is more readily available than cellulose.

Now that we have understood the difference between cellulose and starch, let’s take a look at how they are different from each other on the basis of viruses.

Conclusion

cellulose and starch are two of the most important plant nutrients. They have different functions in plants, and it’s important to understand the differences between them if you want to grow healthy plants. Starches are used for energy, while cellulose provides structural support. Most students learn about starch early on in their studies of plant science, but cellulose is often overlooked. It’s a mistake to ignore this important nutrient, however, so make sure you know how to identify it and use it correctly in your garden or farm.
