So, are you ready to complete the chapter within time and revise it for the examination? Stay tuned with our coaching pattern and you will be able to do your best. Here we start it for you: 

What is Sucrose?

Sugar or plain sugar or cane sugar, whatever the name, is such an important item that adds some sweetness to your life and taste in the kitchen. The chemical name of this sugar is sucrose. In general, we have different types, uses, etc for sugar, sucrose has a chemical formula, meaning, physical and chemical properties based on its structure, etc. Let's have a detailed explanation about sucrose.

The chemical formula for sucrose is C12H22O11. The sucrose meaning can be constituted by the structure and arrangement of sucrose molecules. It is a molecule connected with both glucose and fructose with the help of glycosidic bonds. 

In 1857, William Miller had found the molecule of sucrose and coined the term. The refined form of sucrose is nothing but sugar which can be used in several recipes to add sweetness to them.

Structure

As glucose and fructose are two monosaccharides, sucrose can be considered disaccharides. The disaccharides sucrose can be obtained by the linkage of the able molecules. This can be done with the help of glycosidic bonds. So the linkage is also known as glycosidic linkage. The structure of the sucrose is Crystal form and it is soluble in water. Sweetness is the basic feature of sucrose. The chemical structure of sucrose can be shown below.

Monosaccharides and disaccharides are two categories of sugar.

Features of Sucrose

• The Chemical Formula of Sucrose is C12H22O11.

• It has a Molar Mass or Molecular Weight of 342.30 g/mol.

• The Density of sucrose is 1.587 g/cm3

• Its physical appearance after purification is white, crystalline solid.

• It starts decomposing at 459 K.

Sucrose in Plants

There is a predominant role of sucrose in plants. Sucrose will act as an essential career of carbon for the plants as it is a carbohydrate. Also, the solubility nature of sucrose in water gives it a stable structure. The plant cells help to send the sucrose to the phloem with the support of special vascular tissue. 

Differentiation Between Glucose, Fructose, and Sucrose

All three cases, sucrose, fructose, glucose, and all types of sugar have few differences. They are as follows- 

• Glucose has the least sweetness when compared to fructose and sucrose. Sucrose is sweeter than glucose and less sweet than fructose. Fructose is the sweetest of the other two.

• Glucose is available in processed foods to add a sweet taste to them. It is like a carbohydrate-based food. It has both good and bad effects on the body. Whereas fructose is known as fruit sugar. It can be found in real fruits and vegetables. As it is a natural source of sucrose, it doesn't have much negative effect on the body.

• Sucrose, glucose, fructose may differ in absorption and digestion also. As sucrose is a disaccharide, it can be broken down into different molecules, and then only it can be absorbed by the body. It is a longer process. But the separation starts from the mouth itself. 

• The glucose can be easily digested and absorbed by the body directly from the liner of the small intestine. It is used widely to improve energy and to raise the blood sugar level in the human body. Whereas fructose can be digested and absorbed a bit easier than sucrose but takes time when compared to glucose. Because the factors need to convert into glucose form they only can be absorbed by the body.

Accumulation of Sucrose 

The process of accumulation of Sucrose in sugarcane is a step-by-step process. It can be done with the help of the photosynthesis process. The sucrose can be transported into the stem with the help of the following. If the sucrose can be stored in the stem, it can be extracted during the last phase. Also, there is another possibility that the sucrose can be stored in the stem or can be transferred to other parts which give rise to new growth. It has both pros and cons. If the new growth starts, it leads to another cycle of photosynthesis. But the amount of sucrose available in the stem gets reduced. The entire process of extracting sucrose in sugarcane can be shown below.

Bottom Lines

The use of sucrose can be found in preparing several food recipes. These food items became a livelihood for many people. The use of sucrose is also found in some chemical reactions. Hence the sucrose is a disaccharide molecule with a combination of both glucose and fructose. 

Journey of Sucrose: Then and Now

Before we highlight different milestones associated with the journey of sweetness and sugar and our inner cravings for it, we should have some established definitions in our minds. Carbohydrates might be simple or complex, these are known as the micronutrients that we require for our bodies as a main energy source. 

Simple carbohydrates oe the sugar that is single such as galactose, glucose, and fructose also offers the foundation for a double sugar such as table sugar (sucrose) and complex sugars such as starch. The digestive carbohydrates that we eat, will break down gradually into one of the three molecules also known as small sugar units that are absorbed easily by our intestines. 

Our ancestors also used to eat sweet foods like dates, wild fruits, and honey for obtaining sweetness. Honey used to be the initial sweet agent that has been explored by humans. It is believed that this was explored by Egyptians. They discovered it in the form of wild honey and decided to gather it. They collected it after getting to know the fact that it will offer them pleasure and energy. 

Once they got to know the production methods, they started keeping the bees for the production of honey. The next source was a condiment, yes you got it right it was sugarcane. This originated in the parts of Asia. Initially, Arabs conducted the extraction and refinement of Sucrose and they made it popular via trade. 

This exploration took a shape of intensity as Europeans went for establishing huge sugarcane plantations in the Caribbeans and Pacific colonies. And, it was also a huge reason for transatlantic slavery. After the European conflicts, French people picked another path and began to extract sucrose via sugar beets and they also cultivated it as a sigarcase substitute. This is a story of the 19th century that played a key role in increasing the production of sugar as later transformed into sweeteners (primarily corn-related sweeteners). Today, the sucrose history seems to be intertwined with the destruction of the ecosystem due to the result of deforestation for the sake of developing sugar plants and it is having negative results on public health. 

After knowing the detailed history of sugar, the production and consumption style were the factors that contributed to the sugar cravings. And, it resulted in both social, environmental, and health subjects. Fruits and plants are the main sources of sugar that is said to be natural, and for these, our ancestors also craved them. This is because they considered it a great energy source. And, they transferred this sweet tooth to their coming generations as well. But, we need to understand that we do not require the same amount of calories that our ancestors required as they used to do more physical tasks than we do these days.
