Oligosaccharides – this is a kind of polymeric carbohydrates, the molecules of which contain a small amount of monosaccharides in the chain. The human body, they play an important role in forming a healthy microflora. Nutritionists call this process of "prebiotic effect", because due to the special functions of oligosaccharides in the intestine increases the activity of bifidobacteria and lactic acid bacteria. Eating foods rich in these carbohydrates stimulate the growth of other species of beneficial bacteria and microorganisms.

Independently produce these vital nutrients, the human body is, unfortunately, not able. Therefore, to stay healthy, beautiful and cheerful, you must adhere to the balanced diet containing all the group of carbohydrates.

Features and benefits of oligosaccharides to the human body

The Beneficial microorganisms living on the walls of the colon and creating there healthy microflora to a normal existence is necessary to the human diet necessarily present oligosaccharides. This is an extremely useful and necessary for proper functioning of the human elements. Such substances are defined partially fermented by intestinal bacteria that promote healthy digestive tract microbiocenosis. These food compounds are called prebiotics.

Insufficient carbohydrate intake

The importance of the consumption of oligosaccharides are obvious: the shortage in the human body need disaccharides leads to various diseases and pathologies are not only gastrointestinal tract but also the whole organism. The intake of carbohydrates is necessary for normal functioning of the brain and muscles. With insufficient consumption of these compounds in the body is a violation of protein and fat metabolism, in the blood and begin to accumulate harmful products of oxidation of amino acids and fatty acids.examples of oligosaccharides

What products meet oligosaccharides - prebiotics?

The nature of these substances in large quantities contained in many plants, fruits and vegetables that we eat in your diet-greens, honey, apples, bananas, cabbage, bulb onions, garlic and other vegetable crops. Many of the oligosaccharides found in milk and lactic acid products. A sufficient amount is present in various cereals, beans, soy, beans and corn. Very often they are included in the special biologically active additives to food.

The Role of carbohydrates in human body

Carbohydrates are of great importance for the human body and must be present in his daily menu. These compounds carry multiple functions, ensuring the normal existence of people. This should include:

  • Energy function. Due to the oxidations of the various components of carbohydrate compounds releases energy that meets the needs of the body. Therefore, the importance of carbohydrate intake in the diet is obvious, because the cells of our body are working all the time.
  • Hydrostatically function. Thanks to the use of carbohydrates in the intercellular fluid of the body contains the necessary amount of ions of magnesium, calcium. These substances bind water molecules.
  • Structural feature. Some carbohydrates are part of many connective tissues of the human body. Moreover, in a complex with proteins contribute to the formation of enzymes, steroid hormones and other important elements that are part of the intercellular membranes, blood plasma and are involved in crematorial processes.
  • Protective function. Carbohydrates provide elasticity of the vessel walls, are part of the mucous membranes and synovial fluid.functions of oligosaccharides

However the use of carbohydrates is not limited to sustenance of the human body. Knowing some properties of oligosaccharides, today they're used extensively in many industrial processes. Involve in the production of various food products. Because oligosaccharides are a kind of natural preservatives.

Classification of carbohydrates

This category of compounds can be divided into three groups:

  • Simple sugars (also called monosaccharides);
  • Oligosaccharides (or polymer compound with a glycoside bond)
  • Polysaccharides – biopolymer compounds having a large molecular weight.

properties of oligosaccharides

What are the differences between carbohydrates

The Monosaccharides are the simple carbohydrates, they do not undergo hydrolysis in the human gut and are rapidly absorbed. The most important representatives of this group are considered to be hexoses and pentoses.

Polysaccharides and oligosaccharides – more complex compounds. Polysaccharides - high molecular weight biopolymer compounds which in turn are divided into digestible (starch and glycogen storage compounds) and indigestible (dietary fiber).

Oligosaccharides consist of several residues of simple carbohydrates. As they contain from 2 to 10 residues of monosaccharides, they are divided into disaccharides, trisaccharide, etc. are of crucial importance to the human body represent disaccharides.

So, sucrose,contained in cane or beet sugar, is found in plants in the form of a solution, accumulate in their stems and roots. Lactose-a carbohydrate of animal origin, are contained in their milk. Trehalose is found in certain algae and fungi. Maltose in free form is not found, it contains as an intermediate product of starch hydrolysis during germination of rye and barley grains.oligosaccharides polysaccharides

Chemical properties

The Basic examples of oligosaccharides, the most common and frequently used in food that contains two monosaccharide is sucrose, maltose, trehalose and lactose. Any chemical processes involving oligosaccharides, due to the ability to either hydrolyzed, laminating at the same time on the monosaccharide residues from which they were composed. For example, in the hydrolysis of maltose formed two glucose and lactose is formed from galactose and glucose. Sucrose, in turn, breaks down into glucose and fructose.

Functions of oligosaccharides in various processes

Oligosaccharides, like other macronutrients, the primary functional feature is considered to be hydrophilic. It is due to the presence of large number of Oh-groups that interact with water molecules. The result of the binding of water due to the structure of the carbohydrate. For example, despite the same number of hydroxyl groups, the hygroscopicity of fructose is much higher than glucose. And much gigroskopicna sucrose lactose or maltose. Using a variety of water features carbohydrates, they deliberately involve in different processes.monosaccharides oligosaccharides

When you freeze raw materials, semi-finished and finished products, depending on valid or invalid excess moisture, it may be appropriate to use sucrose, lactose or maltose.

In addition, oligosaccharides are compounds, which bind the volatile aromatic substances and affect the final color of the product in the drying processes. So they are often specially introduced into the product to achieve a good result.

Today this group of carbohydrates is widely used in the manufacture of various drugs, biologically active additives in cosmetology.
