Nutritious for Teens - Protein

As an element with the protein, amino acid performs a important role in sustaining the dynamic equilibrium of protein in the physique. In regard to the important activity, the amino acid is absorbed by digestive tract to begin with, and then is transformed and synthesized to keep up the dynamic equilibrium in the body. If “disorder of dynamic equilibrium” occurs in the body, the metabolism with the body will get out of order and even pathologic change on organ or histiocyte may be caused. Amino acid serves as nutrient or “food” for all organs, viscera and cells in the physique. In other words, the amino acid is the nutrient for all cells in the physique. Every organ within the physique and the viscera are made up of different cells, such as liver cells within the liver, brain cells in the brain, medulla micronucleus cells in the medulla and skin cells within the skin. Different kinds and number of the amino acid are needed for different forms of cells, for instance, lysine is required for the development of skeleton in one's infancy; arginine is required for liver; glutamic acid is required for stomach and intestine; tyrosine is required for central nerve. "Disorder of dynamic equilibrium” and diseases will emerge when the eighteen forms of amino acid lack. If cells in one part of the physique can't absorb enough nutrients, the exercise of these cells will become less active, and then immune system in this part with the physique reduces and leads to the reduced ability of someone to prevent diseases or resist diseases. Therefore, virus cells and cancer cells cause trouble; diseases occur and pathologic change may be caused. It really is the mechanism for the occurrence of “disorder of dynamic equilibrium”, “disorder metabolism” and reduced ability to resist diseases and the severe pathologic change. Eighteen forms of amino acid are needed for the body. Nonetheless, only ten forms of amino acid which are called “unnecessary amino acid for the body” can be transformed and synthesized by taking protein. They are glutamic acid, aspartic acid, serine, proline, glycine, tyrosine, histidine, arginine and cystine. Other eight forms of amino acid including lysine, tryptophane, phenylalanine, methionine, threonine, leucine, isoleucine and valine can't be transformed and synthesized by the body. They are called “necessary amino acid for the body”. In other words, they are necessary amino acid although they can't be transformed and synthesized by the body. These eight forms of amino acid must be absorbed by eating foods. How to absorb necessary amino acid for the physique? There are two approaches: one is to eat biological foods, such as soft shelled turtle and abalone, and another way is to consider amino acid powder. Taking natural keratoprotein as the active pharmaceutical ingredient, the amino acid powder contains eighteen forms of free amino acid. It has been taken by people for a long time and enjoys the fame of “cutting-edge nutrient”.
