Proteins in a human body are the main construction material which allows to develop and grow at everything to cages without exception. They perform necessary functions which cannot be compensated by means of other elements as contain special amino acids. Therefore today we will discuss why the person needs proteinaceous food, and we will consider the list of the products rich with these organic compounds.
Description and general characteristic
Squirrels act as the complex organic compounds consisting of amino acids — them there are about 80, and 22 of them are in food.
The mass of a human body in the majority consists of protein as it is the main component of muscles, ligaments, glands, bodies.
We advise to read about the principles of functioning of muscles, bones and joints.
Squirrels who are components of a human body it is impossible to find in the same state necessary for full assimilation an organism, in one food product, all of them undergo long process of processing further to perform the functions. The protein which we eat is split on amino acids, and further the human body takes them as a basis in the course of the structure of proteins necessary for it.
Whether you know? For the first time secreted protein in 1728 from wheat flour under the guise of Iacopo Bartolomeo Beccari's gluten — the Italian scientist. This opening is considered the major step for a further research of protein.
Properties of proteins are directly connected with their structure and amino-acid structure.
Amino acids happen:
- replaceable — their synthesis is possible thanks to other organic compounds;
- irreplaceable — they are also called vital, their synthesis in an organism does not happen, and they have to get to the person from food.
All living organisms in the course of activity are capable to develop a special type of organic compounds which is necessary for a specific individual.
Products of splitting are soaked up from intestines in blood, coming to a liver where some of their part is applied to the synthesizing albumine processes and also special proteins. After that there is their transportation in other bodies and fabrics.

Subsequently they participate in processes of formation of necessary elements of a human body, as structural or power material.
Process of digestion of organic compounds is connected with a stomach and a small intestine which are the place of their splitting. Therefore if the person has problems with a pancreas — it will badly affect this process.
It is possible to calculate quantity of the acquired protein which the person receives from products with the high content of protein, considering quality of food and also from where they occur. Organic compounds of animal origin in comparison with vegetable are acquired one and a half times better. The splitting of proteins which arrive from molokoprodukt, eggs and fish happens most quicker. Further on the speed of splitting there are proteins of meat products where it is possible to include beef, pork and mutton. More slowly process of splitting happens to the organic compounds received from the bakery products made of high-grade flour.

It should be noted that gelatin which consists of collagen has the highest content of protein. The received organic compounds in this case are considered as defective, but are split quickly enough. Besides, thanks to gelatin, there is a fibrillation process stimulation therefore such product is recommended to be used to patients who underwent operations on bodies of digestive system and also having gastrointestinal bleedings, maxillofacial injuries.
Whether you know? All living organisms (their dry weight) on the planet consist at least for 50% of protein. And at viruses the protein content can be in limits of 45-90%.
The main functions and advantage for an organism
The considered organic compounds are necessary for achievement:
- Plastic influence. Squirrels act as construction material for cages and intercellular substance. Interacting with phospholipids, there is an education a skeleton, being in biological membranes.
- Catalytic effect. Protein is considered a body of any enzyme. And as is well-known, enzymes are necessary for assimilation of feedstuffs, they also regulate all processes of exchange in cages.
- Hormonal effect. In the majority, hormones act in the form of proteins or polypeptides, carry hypophysis hormone, insulin and paratireoidny hormone to them.
- Specificity. Organic compounds allow to provide identity in specific specificity which is called the main reason for stimulation of the immune system and allergic reactions.
- Transportation functions. Proteins allow to transport oxygen with blood, to supply an organism with lipids and carbohydrates, useful substances, hormones and medicine. Specific proteins allow to provide enrichment with useful substances and vitamins an organism, they are transported on cellular membranes and subcellular structures.
Squirrels also maintain elasticity of skin, are responsible for health of hair and nails. These connections promote maintenance of a body in a tone as as splitting they influence formation of muscles. It is also necessary to note that proteins are the main stimulator of metabolism.

Daily requirement and norm
Amount of protein food which is received by the person from food it has to be controlled because in case of the use of insufficient quantity, there are violations in bodies and systems, leading to irreparable consequences.
Consumption of a protein over standard daily rate is also undesirable therefore it is necessary to consider these features and to regularly count quantity of the consumed protein products, depending on physical activity and features of an organism. Also It should be noted that the quantity of a protein which is necessary for the person differs depending on a floor.
The method of a pyramid of food consists in division of products into groups: from irreplaceable which have to become a basic diet, to undesirable which quantity has to be minimum. Proportions of products are defined by their situation in a pyramid.
Men
The norm of proteins which the male body in day has to receive is from 70 to 120 g, and depends on growth and weight and also physical activities.
The table according to which you can calculate necessary amount of protein to you is given below. It should be noted that the quantity of a protein in day decreases depending on age.
Important! It is remarkable that in the period of stressful situations the need for a protein considerably increases and is not present value, how many years to the person any more.
To people who seriously play sports more protein has to come to an organism, the norm is considered from 1.5 to 2.5 g on 1 kg of weight of the person a day.
If you visit the gym and train according to the general program, the amount of protein in day has to be equated to 0.8-1 g on 1 kg of weight of the person.
Women
The quantity of the proteins necessary for a female body, not strongly differs from requirement of a male body and is about 60-90 g a day. During sports the quantity of a protein has to be increased up to 1.7 g by 1 kg of weight a day.

Once also requirement distinguishes pregnant women in protein. In development of the kid, it plays an important role as participates in the structure of an organism of the child therefore the amount of the consumed proteinosoderzhashchy food the woman has to be not less than 2 g on 1 kg of weight in the family way.
Shortage and surplus
If the human body suffers a shortage of a protein, it will have pernicious effect on the state of health, the same can be told also about a surplus which can also cause some problems.
Surplus
If consumption of protein food is above standard daily rate, there can be processes of an overload of a liver and kidneys which are connected with products of disintegration of a protein. If the consumed organic compounds of animal origin are much, then in an organism uric acid which can become the reason of development of stones in kidneys or gouts will begin to collect. If the organism is overloaded with a protein — it can strengthen putrefactive processes in intestines, load sekretorny function of the digestive device, increase acidity in a stomach.
On consumption only of proteinaceous food the sensational diet of Dyukan is constructed. At it there is a lot of as the supporters who managed to lose weight and the opponents who are going on about unconditional harm.
Shortage
The lack of protein is more dangerous, than its surplus. The shortage of a protein can be observed when there is a long violation of balance in receipt and disintegration of proteins if disintegration processes are in the lead. Such situation arises because of insufficient quantity of the consumed protein, or if the proteins with the minimum biological value which are characterized by the shortage of irreplaceable amino acids are consumed. If the food allowance which is provoked by various factors is broken, both social and economic, and psychological — it can cause alimentary proteinaceous insufficiency. But often the shortage of protein in an organism is caused by various diseases which are connected with violations of the digestive bodies connected with a pancreas and intestines.
Important! It is necessary to consume a protein in bigger quantity to the person in the period of tuberculosis, infections, renal pathologies, operational intervention, burn consequences, malignant tumors, strong blood losses.
The shortage of protein in an organism leads to deterioration in work of digestive system, strikes endocrine, haematogenic, immune and other systems and also leads to an atrophy of muscles. Also other useful substances begin to be acquired badly in an organism that leads to hypovitaminosis and decrease in immunity.

Where to look for proteins: products sources
Squirrels are different origin therefore it is necessary to know what products contain a lot of protein, they are presented in the list of products of animal and plant origin.
Animals
Daily the person has to use beef, pork, meat of a rabbit and fowl.
If to consider all grades of beef, veal as it is well acquired is considered the most low-calorie of them, it is possible to use this meat even in the course of weight loss. Also the squirrel in a liver, kidneys, a spleen, language, brains, an udder is a lot of.
The protein which is contained in fish is much better acquired — up to 98%. Most of all it in a tuna (about 25%), is also very useful to use fish caviar.
Most quicker the proteins which are contained in egg can be acquired, but it should be taken into account that this product more high-calorie, than, for example, veal.
It is important! In order that proteins were better acquired, they are recommended to be used together with the juicy vegetables which are not containing starch to which carry cabbage, vegetable marrows, cucumbers, onions, a celery, a garden radish and parsley.
Vegetable
First of all, it should be noted that vegetable food supplies an organism with useful cellulose which after digestion turns into the protein necessary for an organism. Let's consider what contains vegetable protein.
It contains in soy, lentil, oats, rice, peas, barley and also in nuts and sunflower seeds.
We advise to read about pluses and minuses of a soy protein, the recipe of tasty lentil, advantage of pumpkin sunflower seeds.
Also a lot of cellulose contains in cabbage, carrots, eggplants, potatoes and greens. In order that the organism received all set of useful amino acids, it is necessary to eat the most various vegetable food.
Whether it is possible to do much harm protein
Protein can also do harm as because of it there are food allergies which are shown in the form of impassioned reaction of immunity of the person.
It is also very important to consider quality of protein as by scientists it was proved that if the person uses exclusively red meat — it increases risk of death from cardiovascular diseases more, than by 10%. Also red meat increases risk of development of diabetes 2 types by 12%.
But if to replace it with proteins of plant origin which contain in nuts, wholegrain cereals or low-fat dairy products then, on the contrary, the risk of development of diseases decreases.
Thus, proteins are an irreplaceable component of a human body and have to arrive daily with food in order that all processes proceeded normally, and bodies worked well-coordinated. Therefore it is important to consider recommendations and it is correct to select proteinaceous food which list of products can be found in this article.
