Collagen can be subdivided into: macromolecular collagen and vital collagen peptides from China manufacturer. Usually, the jelly of pig's trotters we eat contains collagen, but it is a macromolecular protein with a molecular weight of more than 300,000 Daltons. The collagen whose molecular weight is controlled within 6000 Daltons by techniques such as alkali and enzyme digestion is called vital collagen peptides from China manufacturer (peptide is a substance between amino acids and macromolecular proteins).

Because of its low molecular weight and excellent water solubility, vital collagen peptides from China manufacturer are easily absorbed by the intestinal wall and are more likely to exert biological functions. In recent years, vital collagen peptides from China manufacturer have gradually become a research hotspot in the field of food. In addition, vital collagen peptides from China manufacturer also have a high degree of biocompatibility and degradability, giving them superior cell regulation capabilities; and compared with synthetic polymer materials, they have low immunogenicity and are more likely to penetrate deep into the skin tissue. These advantages make it widely used in the fields of medicine, biological materials and beauty and skin care.
Collagen with a large molecular weight is not conducive to direct absorption by the human body, while vital collagen peptides from China manufacturer with a small molecular weight are usually easier to be digested and absorbed by the human body.
