Immunoglobulins; are highly specific antibody proteins that are produced in response to specific antigens. Fibrinogen; prevent the damage a blood vessel to lose blood. Surprisingly, you'll find very little mention of Stanley Biber on most websites. In the formation of the human body requires more than 100,000 different types of protein, and all are necessary for good health. The protein structure is very complex, not only depends on the amount of amino acids that make up (usually between 80 and 300) and their sequence, it is also determining the position to the amino acid chain adopts in space. The absence or change of position of a single amino acid, or an irregular folding would lead to the deactivation of the protein, or poor performance, with serious consequences for health. Where does the proteins our bodies need? Mainly from the food we eat.
That does not mean that selects and uses the different proteins they contain, as the cells break down food proteins, in the elements that compose them, and use these compounds, amino acids, to make the proteins they need. In fact, what we deliver through a balanced diet, proteins are not necessary, but the amino acids needed to synthesize (build) various proteins that our body requires. In the preparation of the proteins that our body needs 20 different amino acids are used, 8 of which the essential amino acids, can only be obtained from ingested food. But not all foods containing them. Only meat, fish and eggs contain so-called "quality protein", which provide all essential amino acids. Fruits, vegetables, legumes and cereals (with some exceptions) do not contain "quality protein." But the amino acids absent in some products are abundant in others. The key to a healthy diet is eating foods that contain "high-quality protein, but eating a variety of foods, although all are of plant origin. There is no reason to consume foods containing large doses of protein. If the power is varied, there will be sufficient quantities of essential amino acids. The "quality" of the protein consumed, it has great relevance. The contribution of amino acids needed to be secured by feeding only meat, but it would be a diet deficient in other nutrients. Although proteins have an important role, not only to take account in a healthy diet.
