These are macromolecules composed of carbon, hydrogen, oxygen and nitrogen. Most also contain sulfur and phosphorus. They are formed by the union of several amino acids linked by peptide bonds. The order and arrangement of amino acids in a protein depends on the genetic code, DNA, of the person.

Proteins constitute about 50% of the dry weight of tissue and there is some biological process that is independent of the involvement of these substances.

The main functions of proteins are:

* To be essential for growth. Fats and carbohydrates can not replace, it does not contain nitrogen.
* Provides essential amino acids essential for tissue synthesis.
* It is material for the formation of digestive juices, hormones, plasma proteins, hemoglobin, vitamins and enzymes.
* They act as shock absorbers, helping to keep the reaction of various media such as plasma.
* They act as biological catalysts accelerating the speed of chemical reactions of metabolism. Are enzymes.
Act as transport of gases such as oxygen and carbon dioxide in the blood. (Hemoglobin).
* Act as a defense, antibodies are proteins of natural defense against infections or foreign agents.
Allow cell movement through the actin and myosin (muscle contractile proteins).

* Resistance. Collagen is the major integral protein of the supporting tissues.

Energy, proteins provide the body with 4 Kcal of energy per gram ingested.

Proteins are classified according to their chemical structure:

Simple proteins, amino acids to produce only be hydrolyzed.

Albumin and globulin, are soluble in water and dilute salt solutions (eg, lactalbumin of milk).

Glutelin and prolaninas: They are soluble in acids and alkalis, are found in cereals mainly wheat. Gluten is formed from a mixture of glutenin and gliadin with water.

Albuminoids: They are insoluble in water, are fibers, including hair keratin, collagen connective tissue and fibrin blood clot.

Protein conjugate: Those that contain non-protein parts. Eg, nucleoproteins.

Derived proteins: They are products of hydrolysis.

Metabolism, the major end product of proteins is ammonia (NH3) which is then converted to urea (NH2) 2CO2 in the liver and excreted through urine.

It has become a hot topic to talk about the proteins, with the rise of gym, fitness and bodybuilding and everyone knows it’s necessary intake of protein for good muscle development.

It mistakenly believes that food supplements should use to obtain them, when in fact carrying a balanced diet will get all the proteins necessary for the health of the organism and also getting a good muscle development.

We’ll provide a brief overview of the importance of proteins and how to obtain a normal diet.

The proteins involved in all biological processes in the body, and are present in each cell.

Protein is essential for the production of cells and tissues to repair the damage suffered.

Protein deficiency affects the growth in childhood and adolescence, muscle development and prevents a direct impact on the lack of elasticity of the skin, because proteins are responsible for the formation of collagen which is the skin’s natural support.

The proteins, as mentioned involved in all processes of the body so its importance is much greater than described here, but in this case we only regard to muscle development since it is a widespread concern to know how to increase muscle or have a strong and developed musculature.

To increase muscle size is necessary protein intake coupled with carbohydrate, plus vitamins and minerals to achieve a complete nutrition.

Protein-rich foods are:

* Carrnes red (lean)
* Poultry.
* Fish.
* Eggs.
* Dairy.
* Soy.

Plant foods that contain protein but to a lesser extent

* Lentils
* Peas
* Beans
* Nuts
* Almonds
* Seeds
* Grains

Most proteins were obtained from foods of animal origin and within the soybean plant is one that contains complete proteins because the rest of the plant contain incomplete proteins must therefore be combined to obtain adequate nutrition.

Keep in mind that excess protein can cause other health problems such as increased uric acid levels can lead to the accumulation of crystals in the kidneys and joints may also be elevated levels of cholesterol with consequent risk of stroke.

The answer depends on your story. Your body adapts to the intake, it is well researched and documented. The World Health Organization has studies the protein intake of more than a century old.

It takes your body several days to adapt to an intake. The idea that we need to limit the intake for each meal is not correct. If you’re used to consume 20 grams and suddenly consume 200 grams, then chances are you’re serious about eating too much. However, if you constantly consumed 200 grams in one sitting, your body can adapt and start using it.

I’m not suggesting you eat a lot, is just one example.

Protein intake is overestimated and overvalued, especially in an attempt to sell protein shakes, pots, supplements and bars, etc. All supplements are generally used by bodybuilders. Many people that if you train like a bodybuilder gain weight, and that’s not true. Unless you’re racing or really know the basics of bodybuilding or you are under the wing of an experienced coach, probably not justify such high protein intake to the body type and the level that you currently have.

If you consume large amounts of protein, your body will become less efficient at processing it and use it for energy. If you consume small amounts of protein at every meal, your body will become extremely efficient in using and burn less energy, so it pays much more to eat small portions of protein with each meal.

Studies have also shown that maintaining the same calories and increasing calories from protein, or increase the calories in general, even those that come from carbohydrates, both can contribute to gaining muscle mass and improve the breakdown of protein for efficient use.

With Your Ideal Body, there is a healthy and safe alternative to use the science of nutrition and exercise to your advantage and begin to achieve the changes you want in your body permanently.
