Medical practitioners in ancient Egypt predicted the existence of what are now called peptides. These ancient healers believed healthy people had substances in their bodies that could be taken out and put into sick people to cure them. These mysterious factors are among other phenomena that have been demonstrated but not identified for ages.
A Peptide is a molecule formed by combining two or more amino acids, constituting the primary linkage in all protein structures. If the number of amino acids is less than 50 these molecules are named peptides, while larger sequences are referred to as proteins. The amino acids are coupled by a peptide bond. In a peptide bond, the carboxyl group (COOH) of one amino acid bonds with the amino group (NH2) of another, forming the sequence CONH and releasing water (H2O).
Dr. Burzynski discovered naturally occurring peptides and amino acid derivatives in the human body that control cancer, not by destroying cancer cells but by correcting them. He observed that cancer patients typically had deficiency of certain peptides in their blood as compared to healthy individuals. He named these substances antineoplastons. Chemically, the Antineoplastons include peptides, amino acid derivatives and organic acids. They occur naturally in blood and urine, and they are reproduced synthetically for medicinal use. The name of Antineoplastons comes from their functions in controlling neoplastic, or cancerous, cells (anti-neoplastic cells agents).
Every living cell contains Peptides. Peptides play a significant role in fundamental physiological and biochemical functions of life. The research on Peptides is a continuously growing field of science.
