Abstract: As the most abundant functional protein in mammals, collagen has excellent characteristics such as hydrophilicity, biocompatibility and biodegradability. In addition, collagen peptides with smaller molecular weights can be obtained after the degradation of collagen, which are easier to be absorbed and utilized. The presence of metal ions is indispensable for the survival of living organisms. The binding mechanisms of essential metal elements, such as calcium, iron, manganese, chromium, copper and zinc, with collagen have attracted attention for a long time. In recent years, the biological affinity of metals such as titanium, zirconium, and aluminum has gradually attracted attention. After collagen or collagen peptides are chelated with metal elements, the obtained chelating peptides usually have good structural stability and special physicochemical performance due to the properties of metals. This article summarized the characteristics of chelates obtained by the chelation of collagen/collagen peptide and bio-accessible metals, and the focus was played on their binding mechanisms and application characteristics. This review can provide a reference for the application of collagen/collagen peptide metal chelates.
