What is collagen peptide?

Collagen peptide is the product of collagen hydrolysis, with small molecular weight, good biocompatibility and good absorbability. Collagen peptide is widely used in many fields such as health products, cosmetics, food, etc. It can promote collagen synthesis, increase antioxidant enzyme activity, repair naturally aged skin, and also has physiological functions such as improving bone and joint health and promoting chondrocyte regeneration.

What is collagen tripeptide?

Collagen Tripeptide is a peptide molecule formed by dehydration condensation of three amino acids, containing 3 amino acids and 2 peptide bonds. For example, glutathione, composed of glutamic acid, cysteine and glycine, has biological activities such as antioxidant effect and integrated detoxification; collagen tripeptide is composed of glycine, proline (or hydroxyproline) plus one other amino acid. It is the basic component unit of collagen and can be obtained by collagenase hydrolysis. It has multiple biological activities such as calcium supplementation, antioxidant and anti-aging.

The relationship between collagen peptides and collagen tripeptides

Collagen peptides and tripeptides have a certain structural relationship, and tripeptides can be regarded as one of the basic components of collagen peptides. Tripeptides are the smallest structural unit of collagen peptides, consisting of glycine, proline (or hydroxyproline) and one other amino acid. As a component of collagen peptides, tripeptides have similar physiological functions, such as promoting skin health and bone strength.

Collagen peptides perform well in improving skin condition. They can increase skin elasticity and moisture content, reduce wrinkles and sagging. Supplementing collagen peptides can replenish collagen lost by the skin and keep the skin young. Related studies have shown that people who take collagen peptide supplements for a long time have significantly improved skin elasticity and moisture content, and reduced wrinkle depth and area.

The role of collagen peptides in enhancing bone health should not be underestimated. It helps maintain bone density and strength and prevent bone diseases such as osteoporosis. Bones contain a large amount of collagen, which combines with minerals such as calcium to form a solid bone structure. Collagen peptides can promote the absorption and utilization of calcium and improve the toughness and elasticity of bones.

Differences between collagen peptides and collagen tripeptides

1. Molecular weight difference: Collagen peptides are almost more than 1,000 Daltons, while collagen tripeptides are less than 300-500 Daltons, which are very small molecules.

2. Absorption efficiency: Due to their small molecules, tripeptides are better than longer collagen peptides in terms of absorption efficiency in the body. Collagen peptides are composed of amino acids connected by peptide chains one by one, while collagen tripeptides are small collagen structural units formed by removing the three non-repeating amino acids in it, which are the constituent units of collagen peptides. Therefore, collagen tripeptides are more than twice the cost of collagen peptides, and therefore the improved structure will be smaller, and the absorption rate is more than 5 times that of collagen peptides. The tripeptides can be directly absorbed by the human intestine without decomposition, and the absorption rate is as high as 95%.

3. Application areas: Collagen peptides are widely used in the fields of medicine, food and cosmetics, while tripeptides have potential in the fields of oral beauty functional foods, anti-aging functional foods, etc. due to their high absorption rate.
