Q
what biomolecule polymer is present in gelatin
I'm a seasoned industrial engineer with a keen interest in machine learning. Here to share insights on latest industry trends.
Gelatin is a heterogeneous mixture of water-soluble proteins of high average molecular masses, present in collagen. Collagen, found in animal bones, skins, and connective tissues, undergoes partial hydrolysis to produce gelatin. The primary structure in gelatin is collagen's alpha chain, a triple helix comprising repetitive sequences of glycine-proline-X or glycine-X-hydroxyproline, where X can be any amino acid. These sequences are crucial for the physical properties of gelatin, including gel formation. When gelatin is dissolved in hot water and cooled, it forms a gel, making it invaluable in food production, pharmaceuticals, photography, and cosmetic manufacturing. The exact composition and properties of gelatin can vary based on the source and the method of production.
