It has been 112 years since scientists first discovered peptides, and 107 years since they first produced peptides composed of 18 amino acids.

So, what is peptide? Peptide is a kind of small molecule high nutrition material that can be completely absorbed by human cells. It has the advanced physiological functions of repairing cells, nourishing cells and activating cells, which can comprehensively increase human immunity and physical strength. In scientific language, peptide is a kind of compound with molecular structure between amino acid and protein, which is linked by peptide bond. It is also the most active, easily absorbed and highly functional nutrient.

In an experiment, Dr. Billis and Dr. sderin, of the University of London School of medicine, accidentally discovered the presence of polypeptide substances in the human body and won the Nobel Prize in physiology. Five years later, Fischer, a famous German scientist who won the Nobel Prize in chemistry in 1902, made a breakthrough in the study of proteins, amino acids and peptides. In 1907, he was the first to produce peptides composed of 18 amino acids, which became an important scientific news at that time. Since then, it has also established the biological mechanism of peptide's overall effect on human body. He is also known as "the father of world polypeptide"

At present, nearly 100 kinds of peptides have been found by scientists. In terms of nutrition and repair of human cells, yak bone small molecule collagen peptide, glutathione, marine fish oligopeptide and casein hydrolysate play an important role.

In terms of the classification of peptides, peptides are divided into two types: foodborne and iatrogenic. Food derived peptide comes from the food people eat everyday, which is extracted by modern technology. Especially, food derived small molecular peptide has many physiological functions, such as enhancing immunity, antioxidation, assisting in regulating blood glucose, blood lipid, blood pressure, etc. it is especially suitable for the development of special food. Iatrogenic peptide is usually a kind of substance which can be used for clinical treatment. Endorphin and Thymosin are common in the field of peptide.
