A MULTIFACETED PROTEIN

Gelatine is pure protein and a natural foodstuff. It’s made from the skins of pigs and cows or from demineralized animal bones. Collagen is the most important scleroprotein in the bodies of humans and animals. The basic unit comprises a protein chain of about 1050 amino acids. These intertwine in groups of three to form triple helix structures. Cross-linking between many of these triple helices produces collagen fibrils that have a three-dimensional network structure. And it’s these structures that form the connective tissue in skin and bone. The amino acid composition of collagen is atypical for proteins, particularly with respect to its high hydroxyproline content. The most common motifs in the amino acid sequence of collagen are glycine-proline-X and glycine-X-hydroxyproline, where X is any amino acid other than glycine, proline or hydroxyproline.
