Chelating peptide
Numerous biomolecules exhibit the ability to dissolve certain metal cations. Thus, proteins, polysaccharides, and polynucleic acids are excellent polydentate ligands for many metal ions. Organic compounds such as the amino acids glutamic acid and histidine, organic diacids such as malate, and polypeptides such as phytochelatin are also typical chelators. In addition to these adventitious chelators, several biomolecules are specifically produced to bind certain metals (se… WebDec 1, 2024 · The chelating ability of peptides can be affected by several factors, such as protease, hydrolysis time, molecular weight (MW) and amino acid composition of peptide (Guo et al., 2014). Due to the enzyme specificity, the cleavage sites of enzyme are diverse, which results in different peptide sequences and chelating sites for minerals ...
