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.

∙ 13y agoThe glucose molecules form different, larger molecules. The difference between starch and cellulose is how the constituent glucose molecules are arranged.
In starch each glucose molecule is oriented in the same direction.
In cellulose each glucose molecule is "upside down" as compared to its neighboring molecules, meaning each molecule is oriented in the opposite way as the previous molecule in the polymer chain, creating an alternating pattern.

However, for one or the other (I can't remember which), the glucose molecules alternate sides (flip over) in the chain, and on the other, the glucose molecules don't flip over or alternate sides in the chain.
In other words, there are alpha and beta connection points on each glucose molecule, and the connection points of glucose in starch vs cellulose is like this:
AABBAABBAABB
as opposed to
ABABABABABAB

besides, all you have to do is to rearrange an atom or two to get a different compound. What its main components are is a minor factor.

Glucose is considered a monomer because?
Because it is a single hexagonal ring structure.
What does cellulose mean in science?
Cellulose is a long-chain polymeric polysaccharide carbohydrate, of beta-glucose . It forms the primary structural component of green plants. The primary cell wall of green plants is made primarily of cellulose; the secondary wall contains cellulose with variable amounts of lignin. Lignin and cellulose, considered together, are termed lignocellulose, which (as wood) is argued to be one of the most common biopolymers on Earth (chrysolaminarin is often argued to be the other). Only one group of animals, the tunicates, has the ability to create and use cellulose. Some acetic acid bacteria are also known to synthesize cellulose. Cellulose is an organic compound with the formula (C6,H10,O5)n, a polysaccharide consisting of a linear chain of several hundred to over ten thousand β(1→4) linked D-glucose units. Cellulose is the structural component of the primary cell wall of green plants, many forms of algae and the oomycetes. Some species of bacteria secrete it to form biofilms. Cellulose is the most common organic compound on Earth. About 33 percent of all plant matter is cellulose (the cellulose content of cotton is 90 percent and that of wood is 50 percent). For industrial use, cellulose is mainly obtained from wood pulp and cotton. It is mainly used to produce cardboard and paper; to a smaller extent it is converted into a wide variety of derivative products such as cellophane and rayon. Converting cellulose from energy crops into biofuels such as cellulosic ethanol is under investigation as an alternative fuel source. Some animals, particularly ruminants and termites, can digest cellulose with the help of symbiotic microorganisms that live in their guts. Cellulose is not digestible by humans and is often referred to as 'dietary fiber' or 'roughage', acting as a hydrophilic bulking agent for feces.
What are small molecule that form links in polymer chains?
The links in a polymer chain are covalent bonded.
Is monosaccharide a carbohydrate lipid protein or nucleic acid?
"Monosaccharide" is a category of chemical compounds, not a specific compound. Monosaccharides in general are not nucleic acids, though nucleic acids do contain one of two specific monosaccharides (ribose or deoxyribose).
What monomer does cellulose have?
cellulose is a polymer. it a chain of repeating monomers. the monomer for cellulose is glucose. cellulose is a polymer. it a chain of repeating monomers. the monomer for cellulose is glucose.
The monomer unit of polysaccharides such as starch and cellulose is?
The monomer unit of polysacharides such as starch and cellulose is glucose.
What is is the monomer for cellulose?
cellulose is a linear polymer of glucose.
What is the cellulose monomer?
cellulose is a linear polymer of glucose.
Is cellulose a heteroglycan?
Cellulose has an unique monomer - glucose.
Is cellulose and amino acids proper paring for a polymer and its monomer?
No. Cellulose and glucose. Protein is the polymer and amino acid is the monomer.
The monomer that makes up glutose starch and cellulose is the monasaccharide?
The monomer that makes up glycogen starch and cellulose is the monasaccharide?
What is the basic unit of cellulose?
basic unit of cellulose is glucose
What are the names of the monomers used in the synthesis of amylopectin and cellulose?
Cellulose mainly consists of beta-glucose monomers, unlike starch which is an alpha-glucose polymer.
Which carbohydrate monomer is the most common in living organisms?
starch and cellulose.
What natural monomer contains 3000 or more glucose monomers?
Cellulose
What is the monomer unit of cellulose?
It depends on the type of plastic. Different plastics have different monomer units. PVC- Poly Vinyl Chloride has Vinyl Chloride CH2=CHCl as the monomer unit. Polyethylene has ethylene (ethene) CH2=CH2 as the monomer unit. There are many others.
