Sucrose is ... Composition of sucrose

Scientists have proved that sucrose is a part of all plants, in large quantities it is contained in such consumption products as sugar beets and reeds. In the diet of any person, the role of sucrose is large enough.

Sucrose is a disaccharide (a class of oligosaccharides) which under the action of the sucrose enzyme or under the action of acid is hydrolyzed to glucose (it consists of all the main polysaccharides) and fructose (fruit sugar), more precisely, the sucrose molecule consists of the residues of D-fructose and D- Glucose. The basic and accessible to everyone product, which serves as a source of sucrose, is ordinary sugar.

In chemistry, the sucrose molecule is represented by the following formula: C ₁₂ H ₂₂ O ₁₁ and is an isomer.

Hydrolysis of sucrose

C ₁₂ H ₂₂ O ₁₁ + H ₂ O → C ₆ H ₁₂ O ₆ + C ₆ H ₁₂ O ₆

Sucrose is the most important of the disaccharides. As can be seen from the equation, the hydrolysis of sucrose leads to the formation of elements such as glucose and fructose. Molecular formulas are the same for them, but structural ones are completely different:

CH ₂ (OH) - (CHOH) _4- SON-glucose.

Physical properties of sucrose

1. Sucrose are colorless crystals, sweet to taste, which dissolve well in water.
2. 160 ° C - the temperature characteristic for the melting of sucrose.
3. Caramel is an amorphous transparent mass that forms when the molten sucrose solidifies.

Chemical properties of sucrose

1. Sucrose is not an aldehyde.
2. Sucrose is the most important disaccharide.
3. When heated with an ammonia solution, Ag ₂ O does not give a so-called "silver mirror", nor does it form red copper oxide when heated with Cu (OH) ₂ .
4. If you boil a solution of sucrose with 2-3 drops of sulfuric or hydrochloric acid, and then neutralize it with any alkali, after which the solution is heated with Cu (OH) 2, a precipitate of red color will precipitate.

Composition of sucrose

The molecule of sucrose, as is known, consists of the remains of fructose and glucose, which are closely interconnected. Among the isomers that have the molecular formula C ₁₂ H ₂₂ O _11, the following are distinguished: maltose (malt sugar) and, of course, lactose (milk sugar).

Foods that are rich in sucrose

• Rafinated sugar.
• Honey bee.
• Marmalade.
• Gingerbread.
• Dates.
• Straw is sweet.
• Apple pasty.
• Prunes.
• Raisins (kishmish).
• Persimmon.
• Figs are sun-dried.
• Grapes.
• Grenades.
• The loquat.
• Irga.

The effect of sucrose on the human body

Sucrose provides the human body with the necessary energy for its full functioning. It also improves the brain activity of a person and stimulates the protective functions of his liver from the effects of toxic substances. Supports life support of the striated muscle and nerve cells. That is why sucrose is one of the most important substances contained in almost all products of human consumption.

With a lack of sucrose, the following conditions are observed in a person: depression, irritability, apathy, lack of energy, lack of energy. This condition can permanently worsen, if the time does not normalize the content of sucrose in the body. Excess sucrose leads to the following: caries, excessive fullness, periodontal disease, inflammatory diseases of the mouth, it is possible to develop candidiasis and itching of the genital organs, there is a risk of developing diabetes.

The need for sucrose increases in cases when the human brain is overloaded as a result of active activity, and (or) when the human body is exposed to a strong toxic effect. The need for sucrose is sharply reduced if a person has diabetes or is overweight.

Influence of fructose and glucose on the human body

As it was explained earlier, as a result of the interaction of "sucrose-water", such elements as fructose and glucose are formed. Let us consider the main characteristics of these substances and how these elements affect the vital activity of man.

Fructose - one of the types of sugar molecules found in fresh fruits - gives them sweetness. As a result of this, many believe fructose is most useful, because Is a natural component. Also, fructose minimizes glucose (because it has a low glycemic index).

Fructose itself is very sweet, however, the fruits known to man contain a relatively small amount. As a result, a small amount of sugar gets into our body, which is very quickly processed. However, do not enter into the body a large amount of fructose, tk. Excessive use of it can lead to such consequences as obesity, cirrhosis (scarring of the liver), gout and heart disease (increased uric acid level), obesity of the liver and, of course, premature aging of the skin, resulting in wrinkles.

As a result of the research, scientists came to the conclusion that fructose, unlike glucose, accumulates signs of aging much faster. What can I say about the substitutes for fructose.

Based on the material previously proposed, it can be concluded that the use of a reasonable amount of fruit is beneficial to human health, since they contain a minimum amount of fructose. But concentrated fructose should be avoided, because it can lead to a real illness.

Glucose - just like fructose, is a type of sugar, and is a form of carbohydrates - the most common form. Glucose is obtained from starches, it quickly raises the level of sugar in the blood and energizes our body for a sufficiently long period of time.

If you constantly eat foods that are highly processed, or simple starches, which include white rice or white flour, this will lead to a significant increase in blood sugar levels. As a result, certain problems, such as lowering the body's defenses, will result in poor healing of the wounds, kidney failure, nerve damage, increased lipid levels in the blood, a risk of nerve disease (peripheral), obesity, As well as the occurrence of a heart attack and (or) stroke.

Artificial sweeteners - harm or benefit

Many people who are afraid to consume glucose or fructose, resort to artificial sweeteners - aspart or sukrapos. However, they also have their drawbacks. Due to the fact that these substances are artificial chemical neurotoxic substances, substitutes can cause headaches, as well as a high risk of cancer. Therefore, this option, like the previous one, is not 100%.

The whole surrounding world affects the human body, and none of us can protect ourselves from all diseases. However, based on some knowledge, we can monitor the processes of occurrence of various ailments. Also with the use of sucrose: it is not necessary to neglect it, exactly the same as to constantly consume. You should find a "golden" middle and stick to the best options. The options under which your body will feel wonderful and tell you a huge "thank you"! So choose which type of sugar you should use and glow with energy all day.
