How is the mysterious peptide extracted?

1. Separation nd extraction of natural active peptides

Natural active peptides, such as hormones and enzyme inhibitors, were isolated and extracted from bacteria, fungi, animals, and plants.

2. Preparation of active peptides from food protein hydrolysis

Generally, acid hydrolysis is used, which has a simple process and low cost. However, due to severe amino acid damage, it is difficult to control hydrolysis and is rarely used.

3. Chemical synthesis of active peptides

Any desired active peptide can be prepared through liquid-phase or solid-phase chemical synthesis, but their development is limited by high cost, multiple side reactants, and residual compounds.

4. Preparation of Active Peptides through Gene Recombination

The experimental research on preparing active peptides using DNA recombination technology is still ongoing.

5. Enzyme production of active peptides

The product is very safe, the production conditions are mild, hydrolysis is easy to control, specific peptides can be locally produced, and the cost is low. It has become the most important production method.
