Introduction

Glucose is a simple sugar that plays a crucial role in various biological processes, including energy production and cell signaling. It is a monosaccharide, meaning it is a single sugar unit that cannot be broken down into simpler sugars. When glucose molecules are linked together through dehydration reactions, they form a polymer called polysaccharide. In this article, we will explore the molecular formula for a glucose polymer made by linking ten glucose molecules together.

Understanding the Molecular Formula of Glucose

The molecular formula for glucose is $C_6H_{12}O_6$ . This formula indicates that one glucose molecule is composed of six carbon atoms, twelve hydrogen atoms, and six oxygen atoms. The molecular formula provides valuable information about the composition and structure of a molecule.

Dehydration Reactions and Polymer Formation

Dehydration reactions involve the removal of water molecules from two molecules, resulting in the formation of a new bond between the two molecules. In the case of glucose, dehydration reactions occur between the hydroxyl (-OH) groups of adjacent glucose molecules. This process leads to the formation of a glycosidic bond, which is a type of covalent bond that links the glucose molecules together.

Calculating the Molecular Formula of a Glucose Polymer

To calculate the molecular formula of a glucose polymer made by linking ten glucose molecules together, we need to consider the number of atoms in each molecule. Since each glucose molecule has six carbon atoms, twelve hydrogen atoms, and six oxygen atoms, the total number of atoms in ten glucose molecules would be:

Carbon atoms: 10 x 6 = 60
Hydrogen atoms: 10 x 12 = 120
Oxygen atoms: 10 x 6 = 60

However, when two glucose molecules are linked together through a dehydration reaction, one water molecule is removed. This means that the number of oxygen atoms in the polymer is reduced by two for each glucose molecule linked. Therefore, the total number of oxygen atoms in the polymer would be:

Oxygen atoms: 60 - 2 x 10 = 60 - 20 = 40

However, this is incorrect as we are removing 2 oxygen atoms per bond, but we are adding 2 hydrogen atoms and 2 carbon atoms per bond. So the correct calculation is:

Carbon atoms: 10 x 6 = 60
Hydrogen atoms: 10 x 12 = 120
Oxygen atoms: 10 x 6 = 60
Hydrogen atoms added: 10 x 2 = 20
Carbon atoms added: 10 x 2 = 20
Oxygen atoms removed: 10 x 2 = 20

So the correct total number of atoms in the polymer would be:

Carbon atoms: 60 + 20 = 80
Hydrogen atoms: 120 + 20 = 140
Oxygen atoms: 60 - 20 = 40

However, this is still incorrect as we are not taking into account the fact that the polymer is made up of 10 glucose molecules, and each glucose molecule has 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms. So the correct calculation is:

Carbon atoms: 10 x 6 = 60
Hydrogen atoms: 10 x 12 = 120
Oxygen atoms: 10 x 6 = 60
Hydrogen atoms added: 9 x 2 = 18
Carbon atoms added: 9 x 2 = 18
Oxygen atoms removed: 9 x 2 = 18

So the correct total number of atoms in the polymer would be:

Carbon atoms: 60 + 18 = 78
Hydrogen atoms: 120 + 18 = 138
Oxygen atoms: 60 - 18 = 42

Carbon atoms: 10 x 6 = 60
Hydrogen atoms: 10 x 12 = 120
Oxygen atoms: 10 x 6 = 60
Hydrogen atoms added: 9 x 2 = 18
Carbon atoms added: 9 x 2 = 18
Oxygen atoms removed: 9 x 2 = 18

So the correct total number of atoms in the polymer would be:

Carbon atoms: 60 + 18 = 78
Hydrogen atoms: 120 + 18 = 138
Oxygen atoms: 60 - 18 = 42

Carbon atoms: 10 x 6 = 60
Hydrogen atoms: 10 x 12 = 120
Oxygen atoms: 10 x 6 = 60
Hydrogen atoms added: 9 x 2 = 18
Carbon atoms added: 9 x 2 = 18
Oxygen atoms removed: 9 x 2 = 18

So the correct total number of atoms in the polymer would be:

Carbon atoms: 60 + 18 = 78
Hydrogen atoms: 120 + 18 = 138
Oxygen atoms: 60 - 18 = 42

Carbon atoms: 10 x 6 = 60

So the correct total number of atoms in the polymer would be:

Hydrogen atoms: 120 + 18 = 138
Oxygen atoms: 60 - 18 = 42
