And the body constantly builds these new proteins from isolated, singular amino acids. Recent studies have also shown that some amino acid supplements may also be valuable in treating physiological disorders as well as improving endurance. As a result, sales of amino acid supplements have exploded during the last decade. Amino acids are an important class of organic compounds that consists of a basic amino group, an acidic carboxyl group and an organic side chain, which is unique to each amino acid. Amino acids are the key to protein metabolism.
Proteins consist of chains of hundreds or thousands of amino acids joined with peptide bonds.
Enzymes break up the peptide bonds and create isolated amino acids, which are made into different proteins. Lysine - ensures adequate calcium absorption, helps form collagen, aids in production of antibodies, hormones and enzymes. Tryptophan - a natural relaxant, helps reduce insomnia, anxiety and depression. Methionine - principal supplier of sulfur, which prevents hair, skin and nail disorders. Also, helps regulate liver and kidney functions.
