Glucose (dextrose) is a monosaccharide that is a universal source of energy for humans. It is the end product of the hydrolysis of di- and polysaccharides. The compound was discovered by the English physician William Prout in 1802.
Glucose or grape sugar is an essential nutrient for the human central nervous system. It ensures the normal functioning of the body with strong physical, emotional, intellectual stress and a quick response of the brain to force majeure situations. In other words, glucose is a jet fuel that supports all life processes at the cellular level.
The structural formula of the compound is C6H12O6.
Glucose is a crystalline substance of sweet taste, odorless, highly soluble in water, concentrated solutions of sulfuric acid, zinc chloride, Schweitzer's reagent. In nature, it is formed as a result of plant photosynthesis, in industry - by hydrolysis of cellulose,.
The molar mass of the compound is 180.16 grams per mole.
The sweetness of glucose is half that of sucrose.
Used in cooking, medical industry. Preparations based on it are used to relieve intoxication and determine the presence, type of diabetes mellitus.
Consider hyperglycemia / hypoglycemia - what it is, the benefits and harms of glucose, where it is contained, and its use in medicine.
To nourish brain cells, red blood cells, striated muscles and provide the body with energy, a person needs to eat “his” individual norm. To calculate it, multiply the actual body weight by a factor of 2.6. The resulting value is the daily requirement of your body for a monosaccharide.
At the same time, knowledge workers (office employees) performing computational planning operations, athletes and people experiencing heavy physical exertion should increase the daily norm. Since these operations require more energy expended.
The need for glucose decreases with a sedentary lifestyle, a tendency to diabetes, and overweight. In this case, for energy production, the body will use not easily digestible saccharide, but fat reserves.
Remember, glucose in moderate doses is a medicine and “fuel” for internal organs and systems. At the same time, excessive consumption of sweetness turns it into poison, turning beneficial properties into harm.
In a healthy person, the fasting blood glucose level is 3.3 - 5.5 millimoles per liter, after eating it rises to 7.8.
If this indicator is below the norm, hypoglycemia develops, if it is higher, hyperglycemia develops. Any deviation from the permissible value causes disturbances in the body, often irreversible disorders.
Elevated blood glucose increases the production of insulin, which leads to intensive work of the pancreas "for wear and tear." As a result, the body begins to deplete, there is a risk of developing diabetes, immunity suffers. When the concentration of glucose in the blood reaches 10 millimoles per liter, the liver ceases to cope with its functions, the work of the circulatory system is disrupted. An excess of sugar is converted into triglycerides (fat cells), which provoke the appearance of coronary disease, atherosclerosis, hypertension, heart attack, cerebral hemorrhage.
The main reason for the development of hyperglycemia is a violation of the functioning of the pancreas.
Foods that lower blood sugar:
A drop in blood glucose leads to malnutrition of the brain, a weakening of the body, which sooner or later leads to fainting. A person loses strength, muscle weakness, apathy appears, physical activity is difficult, coordination deteriorates, there is a feeling of anxiety, clouding of consciousness. Cells are in a state of starvation, their division and regeneration slows down, and the risk of tissue death increases.
Causes of hypoglycemia: alcohol poisoning, lack of sugary foods in the diet, cancer, thyroid dysfunction.
To maintain blood glucose within normal limits, pay attention to the work of the insular apparatus, enrich the daily menu with healthy natural sweets containing monosaccharide. Remember, a low level of insulin prevents the full absorption of the compound, as a result, hypoglycemia develops. At the same time, adrenaline, on the contrary, will help to increase it.
The main functions of glucose are nutritional and energy. Thanks to them, it supports the heartbeat, breathing, muscle contraction, brain function, nervous system and regulates body temperature.
The value of glucose in the human body:
How many years have glucose been used to intoxicate the body, with hypoglycemia. Monosaccharide is part of blood substitutes, anti-shock drugs used to treat diseases of the liver and central nervous system.
In addition to the positive effect, glucose can harm the body of people in old age, patients with impaired metabolism and lead to the following consequences:
Remember, the delivery of a monosaccharide to the body must be fully compensated by the consumption of calories for energy needs.
The monosaccharide is found in animal muscle glycogen, starch, berries and fruits. 50% of the energy needed for the body, a person receives from glycogen (deposited in the liver, muscle tissue) and the use of glucose-containing foods.
The main natural source of the compound is honey (80%), it also contains another useful carbohydrate - fructose.

Glucose preparations are classified as detoxification and metabolic agents. Their spectrum of action is aimed at improving metabolic and redox processes in the body. The active substance of these medicines is dextrose monohydrate (sublimated glucose in combination with excipients).
Forms of release and pharmacological properties of the monosaccharide:
In addition, the saccharide is used for artificial therapeutic nutrition, including enteral and parenteral.
Indications for use:
In addition, "liquid" glucose is used to dilute drugs administered parenterally.
Isotonic glucose solution (5%) is administered in the following ways:
Hypertonic glucose concentrates (10%, 25% and 40%) are used only for intravenous injections. And at one time, no more than 20 - 50 milliliters of the solution are injected. However, with large blood loss, hypoglycemia, hypertonic fluid is used for infusion infusions (100 - 300 milliliters per day).
Remember, the pharmacological properties of glucose enhance (1%), insulin, methylene blue (1%).
Glucose tablets are taken orally, 1 to 2 pieces per day (if necessary, increase the daily dose to 10 tablets).
Contraindications to taking glucose:
Side effects:
Remember, too rapid administration of glucose is fraught with hyperglycemia, osmotic diuresis, hypervolemia, hyperglucosuria.
Glucose is an important nutrient for the human body.
Monosaccharide intake should be reasonable. Excessive or insufficient intake undermines the immune system, disrupts metabolism, causes health problems (leads to an imbalance in the work of the heart, endocrine, nervous systems, reduces brain activity).
In order for the body to be at a high level of efficiency and get enough energy, avoid exhausting physical exertion, stress, monitor the functioning of the liver, pancreas, eat healthy carbohydrates (cereals, fruits, vegetables, dried fruits, honey). At the same time, refuse to take "empty" calories, represented by cakes, pastries, sweets, cookies, waffles.
