What is the working principle of collagen?

Usually we divide proteins into two types according to their molecular weight: one is protein; the other is small molecule peptide.

Proteins are macromolecules with high species specificity and are difficult to absorb. They must be broken down into amino acids or small peptides through digestion to be absorbed. After being ingested into the human body, protein is decomposed and absorbed and utilized by the small intestine mainly in the form of amino acids and small molecule peptides.

Small peptides refer to collagen biopolymers with a molecular weight below 2000 Daltons, which can be directly absorbed by the human body without being decomposed. Therefore, collagen in the form of small peptides can directly pass through the intestinal wall and enter the blood circulation. The effect is very good.

Small molecule peptides have high biological activity and can play their unique physiological effects even in extremely small amounts. Small molecule biologically active peptides can transmit physiological information, regulate physiological functions, and maintain normal physiological activities of the human body. From cells to tissues and organs, the effects of small molecular biologically active peptides can be found.
