What are collagen peptides?
Collagen peptides - THE EXPERTS in health and beauty
Collagen peptides are a versatile source of protein and an important element of healthy nutrition. Its nutritional and physiological properties promote the health of bones and joints, and contribute to beautiful skin.
Collagen is composed of three polypeptide chains. These so-called alpha-chains are intertwined with each other to form triple-helical macromolecules. They have a sequence of amino acids, of unique size and exclusive structure. In the collagen sequences, glycine (Gly) is present as a tertiary residue. This allows the formation of the three chains in a triple helix structure. Therefore, the common feature for all collagens is a sequence that can be expressed as (Gly-XY) * n, where X and Y are frequently represented by proline (Pro) and hydroxyproline (Hyp), respectively. It is necessary so that the collagen can be mounted on fibrils. These, in turn, form fibers that give the extracellular matrix of the connective tissues their unique structure and strength.
The raw material used to obtain the collagen peptides, as well as for gelatin, is the collagen protein. The collagen peptides, however, are relatively small molecules with molecular weight less than 10,000 g / mol. The peptides are composed of at least 2 and at most 100 amino acids. They are characterized by an excellent solubility in cold water and do not form gels even in highly concentrated solutions.
