Amino Acids and health

It is common knowledge that Amino Acids are the "building Blocks" of the body. This is a two-step process: first, they get together and form peptides or polypeptides, and it is from these groupings that proteins are made. Amino acids make up 75% of the human body. They are essential to nearly every bodily function, and every chemical reaction that takes place in the body depends on them and the proteins that they build.

In this field, Dr. Steven Whiting of the Institute of Nutritional Science points out that an "All or None Law of Protein Utilization" is the rule of thumb. If ALL the amino acids are not present within a close 2 to 3 hour period protein assimilation will not work! Since most vegetarian sources of proteins are incomplete, they must carefully combine the timing and mix of their food intake to provide for complete coverage of all amino acids.

When protein is broken down by digestion the result is 22 known amino acids. Eight are essential which cannot be manufactured by the body are vitally essential for human health, Semi-essential amino acids are amino acids which are normally non-essential, but which must be provided by the diet in special circumstances and when the body's ability to produce them is impaired. The rest are non-essential (can be manufactured by the body with proper nutrition). Sometimes the non-essential should still be supplemented to ensure an optimal available quantity.

Here we offer several Amino Acids which is becoming popular recently, may be helpful to body health.
