Peptide is a compound formed by α – amino acids linked together by peptide bond. It is also the intermediate product of protein hydrolysis. The compound formed by dehydration and condensation of two amino acid molecules is called dipeptide.
Similarly, there are tripeptide, tetrapeptide and pentapeptide. Usually, compounds formed by dehydration and condensation of three or more amino acid molecules can be called polypeptides.
1、 Solid phase synthesis and liquid phase synthesis
There is one company in Silicon Valley that uses this method to produce peptides. They mainly purchase amino acids produced by some fine chemical plants in the world as raw materials to synthesize a single peptide, which is an intermediate of pharmaceutical raw materials.
It is mainly used in the formulation of Western medicine to enhance the efficacy and enhance the absorption speed and absorption rate of the drug.
2、 Acid hydrolysis or alkali hydrolysis
This peptide is mainly found in Japan. Soybean polypeptide produced by acid hydrolysis is a kind of food additive. It is mainly used in food for the elderly and children. Its purpose is to enhance the absorption of food nutrition by these two groups of people.
Japan and China are the only countries in the world with soybean peptides. However, the raw materials, hydrolysis methods and product properties are quite different. The raw material used in Japan is soybean meal, and the hydrolysis method is acid method.
The acidic chemical substances produced in the peptide are difficult to be removed, and they have bitter taste. Therefore, activated carbon is required to absorb and debitter, and the active carbon will inevitably invade the peptide body.
3、 Bioactive peptides produced by enzymatic method
The bioactive peptide was produced by enzymatic method. This peptide is mainly produced in China, which represents the level and trend of peptide research, development, production and innovation in the world.
The bioactive peptide produced by enzymatic method is to hydrolyze the food protein of human body into small molecule active polypeptide with food grade plant protease which is needed by human body. Because of its strong biological activity and diversity, it has attracted worldwide attention and become a hot spot in the world.
Biological extraction of peptides with strong activity, so called active peptides! Only active peptides can produce a good effect on human body! But many synthetic peptides have no activity and need to be screened. Only active peptides can be used safely by human body.
