1、 Structural differences.
Amino acid is the smallest component of protein, and the peptide composed of two amino acids is called dipeptide, and so on. The peptide below 10 is called oligopeptide, and the peptide above 11 is called polypeptide. The molecular weight of collagen peptide is about 1000-3000d, while that of oligopeptide is less than 1000D.
2、 The difference of absorption.
Compared with polypeptides, oligopeptides are smaller. No digestion, direct absorption. Absorption does not need to consume human energy. It will not increase the burden of gastrointestinal function. Oligopeptides with small molecular weight can have higher skin permeability than peptides, and can be absorbed by human skin more easily, and can be 100% absorbed by human body. At the same time, due to the small molecular weight to a certain extent, the biological activity has a qualitative leap. The smaller the molecular weight of peptide is, the shorter the "amino acid chain" is, the easier it will be absorbed and utilized by human body.
3、 Difference in function.
Oligopeptide has the function of carrier. Other nutrients of human food can be carried on its body and transported to human cells and tissues. In the human body to become a means of transport, transport various trace elements to all parts of the human body. It has strong activity and diversity of physiological function. Polypeptides mainly control the growth, development, immune regulation and metabolism of the human body, so that the human body is in a state of balance.
