These peptides support the synthesis and repair of collagen, the primary structural protein in connective tissues, including cartilage, tendons, and ligaments.
Common Name:
Collagen Peptides
Compound Name:
Hydrolyzed Collagen
Chemical Formula:
Varies as collagen peptides consist of different amino acids depending on the source and specific processing methods.
Molecular Weight:
Typically ranges from 3,000 to 5,000 Daltons after hydrolysis.
Sequence and Amino Acid Composition:
- General Composition: Collagen peptides are derived from native collagen and typically contain high levels of glycine, proline, and hydroxyproline, which are the primary amino acids in collagen.
- Sequence Example: Gly-Pro-Hyp-Gly-X, where X can be any of several amino acids commonly found in collagen.
Structure:
Collagen peptides are short chains of amino acids produced by breaking down full-length collagen molecules through enzymatic hydrolysis. They do not form the triple helix structure typical of intact collagen but are rather single-stranded.
Synthesis Method:
Produced commercially by enzymatic hydrolysis of collagen sourced from animals (such as bovine, porcine, or marine sources), which breaks down the native collagen’s triple-helix structure into smaller peptides for better bioavailability.
Solubility:
Highly soluble in water, making them easy to incorporate into beverages, foods, and nutritional supplements without altering texture or taste significantly.
Stability:
Stable at room temperature and in varying pH conditions, suitable for a wide range of food and supplement applications.
Function:
Collagen peptides are used primarily for their health benefits. They are believed to support skin elasticity and hydration, joint health, bone strength, and may promote hair and nail growth. The high content of specific amino acids like glycine and proline supports the synthesis of new collagen in the body.
Benefits and Uses:
- Commonly used in nutritional supplements, cosmetics, and food products.
- Believed to help with skin aging by reducing wrinkles and dryness.
- Supports joint health and may reduce pain associated with conditions like osteoarthritis.
- Promotes bone healing and health by stimulating bone-forming cells.
- Increasingly used in sports nutrition to support muscle repair and recovery.
Side Effects:
Collagen peptides are generally considered safe and are well-tolerated by most individuals; however, some people may experience mild digestive side effects such as feelings of fullness or heartburn.
Regulatory Status:
Regarded as safe food ingredients and dietary supplements in many countries, including the United States (under the FDA) and within the European Union.
