Study on the Coordination Compound of Human-Like Collagen with Copper (II)

The complex of human-like collagen (HLC) with copper (Ⅱ) was synthesized and analyzed in the present study, and the investigation was performed by UV-vis spectroscopy and FTIR spectroscopy. It can be concluded that there exists interaction between HLC and copper, and the complex is a new chemical compound different from free HLC from UV-vis spectra. In the complex of Cu, human-like collagen acts as the ligand, linking the copper ions via both groups of C=O and N-H.
