The essential amino acid

The amino acids according to Rose, can be classified into three groups:

1) Essential
2) Accelerated growth
3) Non-essential or dispensable

The first group are: phenylalanine, isoleucine, leucine, lysine, methionine, threonine, tryptophan and valine.

The second group: glutamic acid, arginine, cystine, histidine, proline, serine and tyrosine.

The third group: esparto acid, alanine, citrulline, the glicosola, the oxiprolina and others.

Each amino acid has a specific function and essential for the organism. Thus, the glutamic acid has a powerful action on nerve cells, especially brain, cystine enters the production of glutathione, essential for the proper functioning of muscles, etc..

Specific functions of the essential amino acids
Lysine: the need for this amino acid is greater in periods of growth and its absence results in menstruation disorders and impaired reproduction. Their daily needs for the adult range between 0.8 grams and 1.6 for optimal minimum.

Methionine: A combination of sulfur that allows the formation of choline, a substance essential for the proper functioning of the liver and kidneys. In some disorders, such as liver failure, jaundice and nephritis chronic deficits often occur methionine and choline, which must be offset with foods containing a large extent.

The daily requirement of methionine from a minimum of 1.1 grams and 2.2 grams optimal.

This amino acid aids in liver detoxification. Their daily needs between 0.5 grams and one gram of minimum optimal.

: This amino acid is essential for reproduction, because if there is danger of lack of sterility. Also diets low in tryptophan produce anemia. Part of tryptophan we ingest through food is transformed into nicotinic acid, which explains antipelagrosa activity of proteins that contain it.

The daily requirement of between 0.5 grams and one gram of minimum optimal.

Valine deficiency disorders arise causes of muscle coordination, and tactile hypersensitivity. Their daily needs is between 0.8 grams and 1, 6 grams.

Leucine: intervened in the repair and formation of muscle tissue. The daily requirement of this amino acid ranges between 1.1 grams and 2.2 for optimal minimum.

Isoleucine: leucine Along with participating in the formation and repair of muscle tissue. The daily requirements range from 0.7 grams and 1.4 for optimal minimum.

This amino acid is converted into tyrosine, essential for growth hormone. Thus, their lack causes an arrest at an early age of this very important role.

The daily needs of the range between 1.1 grams and 2.2 grams of minimum optimal.
