| Abstract: | The chelate complexes
of copper (II) with gelatin and its enzyme hydrolysis products have been prepared. The
proportion of chelates is determined by spectrophotometry. The result shows that 9
grams of copper (II) associates with 100 grams of gelatin to yield a chelate; that 100
grams of different enzyme hydrolysis gelatin chelate complexes 10.411.0 grams of
copper (II), respectively. IR and ESR spectra of three copper (II) gelatin ( enzyme
hydrolysis gelatin ) chelate in solid state at room temperature have been examined. The
complexing state of these copper (II) chelate complexes are discussed. The peptide bond
in these chelate complexes plays an important role. |
