Review of preparation polypeptide calcium from pig bones protease solution

The research achievements of pig bones treatment with enzymes and collagen polypeptide calcium synthesis, structure characterization and calcium chelating mechanism were reviewed. At present, most studies have focused on the synthesis of polypeptide calcium with enzymatic pig bones; the specific calcium chelating peptide characterization process simply reverse illation the mechanism to explore more complex by the product, but can not really reflect each process change of chelation. It needs further exploration and research.
