For collagen and collagen peptides that belong to the same protein, collagen is a macromolecular fibrous hard protein, but collagen peptide is a small molecule polypeptide formed after collagen is treated with artificial protease. This is why collagen and collagen peptides are made of the same amino acids but have different properties.

What is Collagen?

Collagen is the most common protein in mammals and the main extracellular protein in the body. It accounts for about 1/4 of all protein in the body. It is mainly found in fibrous tissues-such as skin, ligaments, tendons, etc.

Its concentration is different in different tissues of the body. Approximately 23% of the collagen is contained in the skull, 50% in the cartilage, 64% in the cornea, and 74% in the skin.

Collagen is a simple peptide composed of a long helical peptide chain, containing 19 to 105 amino acids, including proline, glycine, hydroxyproline, and hydroxylysine.

The molecular weight of collagen is about 300-400kDa. It is insoluble and cannot be absorbed or digested.

Collagen is a strong, non-stretchable protein with strong stretch resistance. Together with soft keratin, it provides skin elasticity and strength. Collagen tissue can be compliant or rigid, depending on the degree of mineralization. Collagen is abundant in bones, cornea, intestines, skin, blood vessels, teeth, intervertebral discs, etc.

What is the real value of collagen?

1. Promote wound healing: Collagen and epithelial cells interact through complex chemical and mechanical signals to promote wound healing and tissue growth.
2. Hemostasis: The sponge structure of collagen can absorb the tissue fluid and oozing blood from such superficial wounds, and collagen itself is a good hemostatic agent, and platelets will adhere to the surface of collagen and activate.
3. Provide raw materials for collagen regeneration: collagen products with good permeability can penetrate deeply into the dermis, so as to provide you with sufficient raw materials to produce your own collagen.
4. Brighten skin tone and spots: Tyrosinase is the largest catalytic enzyme in the process of melanin production. Once its activity is inhibited, the efficiency of melanin production will be greatly reduced.

What is Collagen Peptides?

Collagen peptides are called hydrolyzed collagen, which are short-chain bioactive peptides and are the result of collagenase hydrolysis. Collagen peptide is a small molecule peptide with a molecular weight of up to 5000 Da.

Collagen peptides are obtained through the controlled enzymatic breakdown of the bonds between individual collagen chains. Depending on the enzymatic process applied, a specific pattern of collagen fragments will appear. Collagen peptides are classified according to their peptide spectrum and average molecular weight distribution.

What is the real value of collagen peptide?

Collagen peptides have numerous health benefits. They are the building blocks, renewing the bones, skin, joints, and other body tissues and organs. The health benefits of the collagen peptides include:

1. Skin beauty
2. Healthy aging
3. Bone and joint health
4. Gut health
5. Sports nutrition

Collagen vs Collagen Peptides: What’s the Difference?

Collagen: Collagen is the main extracellular protein in the body mostly found in fibrous tissues,  such as skin, ligaments, tendons, etc.
Collagen Peptides: Collagen peptides are short chain bioactive peptides, produced as a result of enzymatic hydrolysis of collagen.

Summary of Collagen and Collagen Peptides

Collagen is the main extracellular protein in the body, mainly found in fibrous tissues such as skin, ligaments and tendons.
Collagen peptides are short-chain bioactive peptides produced by collagenase hydrolysis.
The molecular weight of collagen is about 300-400kDa, and collagen peptides are small peptides with a molecular weight of up to 5000Da.
Uses of collagen include bone transplantation, tissue regeneration, cosmetic surgery, wound care, and reconstructive surgery. The benefits of collagen peptides include skin beautification, healthy aging, bone and joint health, intestinal health and sports nutrition.
The most common collagen-producing cells are fibroblasts. Collagen peptides are obtained through the controlled enzymatic breakdown of the bonds between individual collagen chains.
Collagen is insoluble in water, while collagen peptides are soluble in cold water.
Collagen is not easy to digest, while collagen peptide is easy to digest.
