Collagen Peptides

Synonyms: Hydrolyzed Collagen, Collagen Hydrolysate, Gelatin Hydrolysate, Peptide Collagen, Collagen Polypeptide, Low Molecular Weight Collagen.

Collagen peptides are short-chain polypeptides derived from native collagen through controlled enzymatic hydrolysis. The hydrolysis process cleaves the triple-helical structure of collagen, yielding low-molecular-weight peptides (typically 2–10 kDa) that are readily soluble in water and easily absorbed. The predominant amino acid sequence repeats Gly-X-Y, where X is often proline and Y is hydroxyproline, which is characteristic of collagen’s unique structure. This composition contributes to the functional properties of collagen peptides in various applications.

Collagen peptides are produced from animal sources such as bovine hide, porcine skin, and fish scales. The raw materials undergo purification, enzymatic hydrolysis, and spray-drying to yield a consistent, high-purity powder. The product is standardized to a minimum protein content (e.g., ≥90% on a dry basis) and controlled molecular weight distribution to ensure optimal bioavailability. Different grades are available to meet specific requirements for food, pharmaceutical, and cosmetic applications.

In the B2B sector, collagen peptides are widely used as functional ingredients in nutraceuticals, clinical nutrition, and personal care products. They are valued for their role in supporting skin health, joint function, and bone strength. With growing consumer demand for anti-aging and wellness products, collagen peptides have become a key component in the development of innovative formulations.

化学構造と性質

Collagen peptides consist of a mixture of low-molecular-weight peptides, primarily composed of glycine, proline, and hydroxyproline. The hydrolysis of native collagen disrupts the triple-helical structure, resulting in water-soluble peptides with improved absorption. The molecular weight distribution typically ranges from 2 to 10 kDa, which is critical for efficient intestinal uptake. The product is stable under normal storage conditions and exhibits good solubility across a wide pH range.

作用機序

• Stimulation of collagen synthesis: Peptides act as signaling molecules to activate fibroblasts, promoting the production of new collagen and elastin in the skin.
• Joint support: Collagen peptides accumulate in cartilage and stimulate chondrocytes to synthesize proteoglycans, helping maintain joint integrity.
• Antioxidant properties: Certain peptide fractions scavenge free radicals, reducing oxidative stress in connective tissues.
• Bioavailability: Low-molecular-weight peptides are absorbed intact into the bloodstream, reaching target tissues such as skin and joints.
